1.1
What is a Safety Instrumented System? A Safety Instrumented System (SIS) is a set of components that includes sensors, Logic Solvers, and final control elements whose purpose is to respond to dangerous plant conditions, which may be hazardous. The Safety Instrumented System must generate the correct outputs to prevent the hazard or reduce the consequences of the hazard. A Safety Instrumented System (SIS) is a form of process control typically used in industrial processes, such as those of Power Generation and Waste Water. The SIS performs specified functions in order to maintain a safe state of a control process when any unacceptable process conditions are detected. A safe state is a state of the process operation where the hazardous event cannot occur. The safe state should be achieved within one-half of the process safety time. International standard IEC 61508 is a standard of rules applied to all types of industry. This standard covers the complete safety life cycle, and has its origins in the process control industry sector. International standard IEC 61511 was published in 2003 to provide guidance to end-users on the application of Safety Instrumented Systems in the process industries. Refer to the Ovation Safety Instrumented System (SIS) User Guide for information about using SIS with Ovation.

1.2 Functions of Ovation SIS
1.2
Functions of Ovation SIS The Safety Instrumented System performs the following functions:
Implements a risk reduction strategy which is intended to reduce the likelihood of a hazardous event causing a catastrophe in a plant.
Validates messages that are sent from Ovation workstations to the safety system. This reduces the risk of sending invalid and perhaps unsafe messages to the SIS. This function is known as SIS Write.
Manages the safety instrumented functions (SIFs) to provide a risk reduction strategy which is intended to reduce the likelihood of a hazardous event. Each SIF defines:
Measurement sensors to use.
Actions to take.
When to apply the actions.
How fast to measure and react.

TERM
DESCRIPTION
Algorithms
Algorithms are self-contained software modules that reside in the Logic Solvers.
Backplane
Backplane is the electronic bus that is part of an SIS carrier. Backplane carries signals between the SIS Logic Solvers and the SIS Data Server.
CIS
Ovation Controller Interface to SIS Data Server (CIS) provides communication between the Ovation Controller and the SIS Data Server.
Control module
When a Logic Server is added to the Studio, four control modules are automatically created and appear under the Logic Solver in the Studio tree. The control sheets are stored in the control modules. All the control sheets stored in a control module are scanned at the same frequency.
CRC
Cyclic redundancy check (CRC) is a mathematical function designed to detect changes to computer data, and is commonly used in digital communications and data storage. A CRC-enabled device calculates CRC code for each block of data. When a new block is received, the device repeats the calculation; if the new CRC code does not match the old CRC code, this indicates that there is a difference between the two blocks of data. This means there is either a data error or a change in the configuration of the data.
DHCP
Dynamic Host Configuration Protocol (DHCP) is a network application protocol used by devices to obtain configuration information for operation in an Internet Protocol network. This allows networks to add devices with little or no manual intervention.
HAZOP
Hazard and Operational Studies. Requirements for SIS projects.
IP Address
Unique number consisting of four parts separated by dots. An example of an IP address is 129.228.36.38. Every computer that is on the Internet has a unique IP address.
Local bus
Communications between Logic Solvers and one SIS Data Server. Achieved via backplanes and extender cables.
Local SISNet (Local peer bus)
Communications of safety data among Logic Solvers connected to one SIS Data Server. Achieved via carrier backplanes and coaxial extender cables.

TERM
DESCRIPTION
LOPA
Layers of Protection Analysis. Requirements for SIS projects.
Netmask
The netmask (also known as an address mask) is a number that identifies the range of IP addresses that are on a local network. The netmask serves as a filter that enables a computer to determine whether it can transfer data directly to another machine on the local network or if the computer must use a router to transfer data.
NAMUR
NAMUR is an international association of automation technology in process control industries. NAMUR alarming can be performed on I/O channels. The NAMUR limits are 106.25% top limit and -2.5% bottom limit.
NTP task
Network Time Protocol. Synchronizes time between the Ovation Controller and its attached Logic Solvers.
Remote SISNet (Remote peer bus)
Communications among Logic Solvers connected to different SIS Data Servers. Achieved via SISNet Repeaters and a fiber optic loop
Shadow algorithm
Term used to describe SIS algorithms when they are loaded into the Ovation Controller. The algorithms are not actually used by the Controller for control, but serve as a visual representation to the user of the algorithms in the Logic Solver.
SIF
Safety Instrumented Function (see page 6).
SIL
Safety Integrity Level (see page 6).
SIS Force
Force operation (see page 298) occurs when a value for an algorithm input parameter (pin) is manually changed, typically for testing purposes.
SIS hardware
Refer to Hardware components (see page 11).
SIS LAN
Communication between a SIS Data Server and an Ovation Controller.
SIS point
An Ovation point that has been used on an SIS control sheet. After the sheet is saved and loaded to an SIS Logic Solver, the point can then be used in SIS control schemes.SIS points can be analog or digital points.
SISNet Ring
Sub-network of SIS components that is contained within one fiber-optic ring (value between 0 and 15).
SISNet
Communications among Logic Solvers, with both local and remote architectures.
SIS Write
SIS Write provides for the validation of messages between Ovation Operator Stations and the SIS Logic Solvers. This function greatly reduces the risk of sending an invalid message to the safety system from the Ovation system.
SNMP
Simple Network Management Protocol (SNMP) is used in network management systems to monitor network-attached devices.

2.1
SIS issues to consider A Safety Instrumented System (SIS) is a form of process control usually implemented in industrial processes, such as those in a factory. The SIS performs specified functions to achieve or maintain a safe state of the process when unacceptable or dangerous process conditions are detected. Consider the following issues when planning a SIS project:
The safe state is a state of the process operation where the hazardous event cannot occur. You should be able to achieve a safe state within one-half of the process safety time.
Even though safety instrumented systems are composed of elements that are similar to elements in a process control system (such as sensors, logic solvers, actuators, and support systems), you should keep the safety system separate and independent from your regular control systems.
The specified functions, or safety instrumented functions (SIF (see page 6)) should be implemented as part of an overall risk reduction strategy since they are intended to reduce the likelihood of a catastrophic release and create a safe state.
The correct operation of an SIS requires a series of equipment to function properly, such as the following:
Sensors capable of detecting abnormal operating conditions, such as high flow, low level, or incorrect valve positioning.
Logic Solvers that receive the sensor input signal(s), make appropriate decisions based on the nature of the signal(s), and change its outputs according to user-defined logic.
Final elements that take action on the process (for example, closing a valve) to bring it to a safe state due to changes in Logic Solver output.
Support systems, such as power and communications, are generally required for SIS operation. The support systems should be designed to provide the required integrity and reliability.
Functional and safety integrity requirements for an SIS are determined from hazard and operability studies (HAZOP), layers of protection analysis (LOPA), risk graphs, and so on. All techniques are mentioned in IEC 61511 and IEC 61508.
You need to verify that during SIS design, construction, and operation, these functional and safety requirements are met.
OW331_47

2.1 SIS issues to consider
You can verify functional requirements by design reviews, such as failure modes, effects, and diagnostic analysis (FMEDA). You can also use various types of testing, such as factory acceptance testing, site acceptance testing, and regular functional testing.
You can verify safety integrity requirements by reliability analysis. For SIS that operates on demand, it is often the probability of failure on demand (PFD) that is calculated. In the design phase, the PFD may be calculated using generic reliability data. Later on, the initial PFD estimates may be updated with field experience from the specific plant in question.
Since it is not possible to address all factors that affect SIS reliability through reliability calculations, you should also have adequate measures in place (for example, processes, procedures, and individual training and certification) to avoid, reveal, and correct SIS related failures
2.1.1 Safety Instrumented Functions (SIFs) Safety instrumented systems are applied to a process to substantially reduce the risk from costly or dangerous failures in industrial processes. The magnitude of risk reduction needed is determined from an analysis of the severity of hazardous process events and their probability of occurrence. Safety instrumented systems are typically comprised of multiple Safety Instrumented Functions (SIFs). Each SIF can be considered a control loop, defining:
Measurements (sensors) to use.
Actions to take (control elements to drive).
When to apply the actions (logic linking the measurements to the actions).
How fast to measure and react.
Every SIF has a Safety Integrity Level (SIL (see page 6)) assigned to it.
2.1.2 Safety Integrity Levels (SILs) Every SIF has a Safety Integrity Level (SIL) assigned to it. SIL is a measure of the risk reduction provided by a SIF based on four discrete levels, each representing an order of magnitude of risk reduction. The factors considered in determining a SIL include:

Device integrity
Diagnostics
Failures
Testing

3.4.3 To power up a simplex SIS Data Server Prerequisites:
Install (see page 24) the SIS Data Server into a 2-wide carrier.
Make sure the system power supply is connected to the SIS Data Server and the power is off.
Make sure the Ovation network is set up in such a way that the SIS Data Server is able to communicate (once it is powered up) with a DHCP server.
Procedure 1. Power up the SIS Data Server's power supply. 2. Refer to the flashing LEDs (see page 27) on the SIS Data Server:
The SIS Data Server attempts to contact the DHCP server and obtain its runtime configuration. Until the DHCP transaction is complete, the SIS Data Server continues to flash its LEDs.
The SIS Data Server initializes in the ACTIVE mode. The ACTIVE LED switches to the constant ON state. The Pri CN and Sec CN LEDs flash to indicate network activity. Note: If the DHCP server does not contain a valid configuration for the SIS Data Server, the SIS Data Server remains in the ‘obtaining runtime configuration’ state until a valid configuration can be provided by the DHCP server.

3.4.4 To power up a duplex SIS Data Server Prerequisites:
Install (see page 24) the SIS Data Server into a 2-wide carrier.
Make sure the system power supply is connected to the SIS Data Server and the power is off.
Make sure the Ovation network is set up in such a way that the SIS Data Server is able to communicate (once it is powered up) with a DHCP server.
Make sure theSIS Data Server's redundant partner is running and active, and that there is a physical redundant connection between the SIS Data Server and its partner.
Procedure 1. Power up the SIS Data Server's power supply. 2. Refer to the flashing LEDs (see page 27) on the SIS Data Server:
The SIS Data Server attempts to contact the DHCP server and obtain its runtime configuration. Until the DHCP transaction is complete, the SIS Data Server continues to flash its LEDs.
The SIS Data Server communicates with its partner over the redundancy link. It detects that the partner is currently in the ACTIVE state. The SDS initializes in the STANDBY state. The STANDBY LED switches to the constant ON state. The Pri CN and Sec CN LEDs flash to indicate network activity.
Note that if the redundancy configuration obtained from the DHCP server by the two SIS Data Servers does not match, the two SIS Data Servers cannot communicate over the redundancy link. The SIS Data Server reboots while the redundant partner continues to operate in the ACTIVE mode. This cycle will repeat itself until the redundancy configuration is the same for both SIS Data Servers. Note: If the DHCP server does not contain a valid configuration for the SIS Data Server, the SIS Data Server remains in the ‘obtaining runtime configuration’ state until a valid configuration can be provided by the DHCP server.
3.4.5 To remove a redundant SIS Data Server Prerequisites 1. Make sure both SIS Data Servers in a redundant pair are running and both have active connections to the Ovation network. Procedure 1. Remove the active redundant SIS Data Server from its slot on the carrier. 2. Refer to the flashing LEDs (see page 27) on the SIS Data Server:
The partner SIS Data Server in the redundant pair detects the failure of its partner and switches to ACTIVE mode.
The STANDBY LED switches to the constant OFF state. The ACTIVE LED switches to the constant ON state. The Pri CN and Sec CN LEDs flash as per network activity. The Pri CN and Sec CN LEDs flash to indicate network activity. Note: If you remove the standby SIS Data Server from its slot on the carrier, the active partner remains unaffected and continues to run in the ACTIVE state.

3.5 SIS Logic Solvers The following figure illustrates the installation of an SIS Logic Solver.
Figure 9: SIS Logic Solver Installation example
3.5.4 Logic Solver redundancy A redundant Logic Solver configuration consists of a pair of Logic solvers mounted in adjacent carrier slots with a redundant terminal block. Each Logic Solver is powered separately. The redundant Ovation SIS Logic Solver modules are connected to the field at the redundant terminal block. No control sheet configuration is required to take advantage of Logic Solver redundancy, as the system automatically recognizes the redundant pair of cards. An integrity error alarm in a redundant Logic Solver pair will notify the operator if a Logic Solver fails. When an Ovation SIS system uses redundant Logic Solvers, this means that any two redundant Logic Solvers run in parallel at all times. Both Logic Solvers read the inputs from the I/O terminals, both execute the logic and both drive the outputs at the I/O terminals. There is no concept of primary and backup or master and slave. The only difference between the two is that the active Logic Solver communicates with both the Ovation Developer Studio and the Ovation Operator Station, and the dedicated safety network (SISnet). The standby Logic Solver is communicating only on the SISnet. If a failure is detected in one of the Logic Solvers, it automatically goes to a failed state. In this condition all its output channels are de-energized. This has no impact on the other Logic Solver or the physical outputs because the other module continues to read inputs, execute logic, and drive outputs. The transition from the active to the standby Logic Solver is therefore completely bumpless.

3.12.2 Voltage Monitor module The Voltage Monitor provides two independent sets of voltage monitoring circuitry in one device. Each circuit is suitable for use in both high and low de-energize to trip applications to extend the voltage input monitoring capability of the Ovation SIS Logic Solver or any other safety PLC digital input compatible with its specified output states. It also supplies a secondary output for non-safety critical monitoring for each input. Refer to the Ovation SIS Accessories Safety Manual for information on proof testing the Voltage Monitor. The state of both outputs for an associated input is controlled by the voltage level of the input with the outputs going to the de-energized state when the input goes below a specified value. The Voltage Monitor is designed to be used with the Ovation SIS Logic Solver to drive the Logic Solver's Digital Input channel or an Ovation Digital Input channel (auxiliary) based on the output of the SIS Relay module.

6.9.1 Viewing SIS points in the Developer Studio hierarchy Ovation points are created through the use of DBID or manually by adding a point using the Ovation Developer Studio. (Refer to Planning Your Ovation System for information about DBID or to the Ovation Developer Studio User Guide for information about adding a point.) Ovation points become SIS points when the points are used by the Control Builder on an SIS control sheet. When the SIS control sheet is saved, the points will appear in the Developer Studio hierarchy in the SIS Points folder under the SIS Data Servers folder When the control sheet is loaded to the Logic Solver, the points now appear in the SIS Points folder under the Logic Solvers folder. The SIS points also appear in the WorkPad area below the Studio hierarchy tree, as seen in the following figure.

DESCRIPTION
Scan Rate
This is the Logic Solver loop time. The available scan rates are 50ms, 100ms, 150ms, and 200 ms per period. The default rate (see page 315) is 50 ms. Since the SIS Data Server sends control module information to the Controller every second, scan rate is not related to update time.
Shadow block Control Task
Refers to a specific Controller area where all the control sheets that contain shadow algorithms are scanned at the same frequency. Points are grouped by control tasks so they can be updated (scanned) at different rates. The rate is set in the applicable Ovation configuration tool during configuration for a Controller drop.

6.11.3 Configuring the Logic Solver Proof Testing tab After you have added an SIS Logic Solver, use the Proof Testing tab (as shown in the following figure) to configure the Logic Solver. Ovation SIS performs an automatic diagnostic whenever a Logic Solver reboots. You can use the parameters in the Proof Testing tab to set the desired configuration for diagnostics:
You can configure the Proof test timer period so that when the timer period expires, there will be an automatic transfer to the backup Logic Solver. This forces a reboot and diagnostics are performed (only available for redundant Logic Solvers). OR An alarm can be generated to indicate that you should reboot the Logic Solver in order to perform the diagnostics.

7.4 Forcing an algorithm input value
7.4
Forcing an algorithm input value A SIS Force operation occurs when you manually change a value for an algorithm input parameter. This means the value is "forced." For example, you might want to see the behavior of an algorithm when it has a certain input value. However, the algorithm might not currently have the input value you need. You can use a Signal Diagram (see page 298) to temporarily force the input value of the algorithm in order to observe the behavior. You cannot force the output of an algorithm to a particular value; you can only force the input to a particular value. However, before you can force an input value for an SIS algorithm, you must turn on the Debug Mode. The Debug Mode is where you can perform functional testing of safety logic by forcing input values for algorithms (see page 298). After you have forced an input value, a blocking icon will appear at the end of the forced input pin of the algorithm in the Signal Diagram. This icon will also appear next to the current value in the Algorithm Summary window. This icon illustrates that the value for the input signal is currently forced and cannot be updated by the system. Note: Remember to remove the forced input value when you want the algorithm to execute normally.
7.4.1 To force an algorithm input value Prerequisites
Make sure the applicable control sheet has been successfully loaded into the Controller and the Logic Solver.
Procedure 1. Access the Signal Diagram window:

7.6 Requiring a reset before outputs can become energized
7.6
Requiring a reset before outputs can become energized The configuration of SIS module logic determines which conditions allow de-energized output channels of the Logic Solver to become energized. It is generally desirable to require an operator reset of the Logic Solver before the equipment under control is allowed to go from a shutdown or tripped state to the normal operating state. However, in some cases, the output channels should be allowed to change from de-energized to energized based on input channel values without operator intervention, for example, as soon as an interlock condition clears. Ovation SIS algorithms provide an easy way to configure SIS module logic to either require or not require an operator reset before applicable output channels can become energized. There are certain situations where a powered Logic Solver keeps output channels de-energized independent of SIS module logic. When the Logic Solver is going through power-up testing following a reset or restart, has detected a persistent fatal error, or is in an unconfigured state, output channels remain de-energized. Otherwise, SIS module logic determines the output channel state. The recommended technique for requiring an operator reset is to use the Cause Effect Matrix (LSCEM (see page 113)) algorithm. It has an RRSn (required reset) parameter or each extensible EFFn (output effect) output of the algorithm. Each EFFn output is connected to one or more output algorithms, which are bound to output channels. When RRSn is True (the default value), the EFFn output cannot transition from 0 to 1 unless STAn (current state) is “Ready to Reset” and RSTn (reset) has been changed to True, typically by an SIS Write from an Ovation Operator station. When RRSn is False, EFFn can transition from 0 to 1 when associated CSn (input cause) have become inactive and other permissives are satisfied, without a reset. The “require reset” option is also available in the two output algorithms, but it should be used only if there is no LSCEM algorithm in upstream SIS module logic.
7.7
Configuring the Logic Solver's response to detected faults It is important to consider the status of the input and output channels of the Logic Solver, as BAD status may indicate a problem that must be addressed. The following topics are described below:
Detecting faults on input channels (see page 310)
Detecting faults on output channels (see page 314)
OW331_47
309
7.7 Configuring the Logic Solver's response to detected faults
7.7.1 Detecting faults on input channels Faults detected by the Logic Solver on input channels can originate in field devices, field wiring, or in the Logic Solver input circuitry. The Logic Solver responds to faults detected on input channels by integrating BAD status with the channel value and annunciating the fault. The Logic Solver does not automatically de-energize output channels when faults are detected on input channels. SIS module logic must be configured to take action based on the requirements of the application. For example, you may want to prevent a trip from occurring in the presence of a fault on an input channel, or cause a trip immediately when a fault is detected, or initially prevent a trip yet cause a trip some time later if the fault persists. SIS algorithms contain parameters to facilitate the configuration of these options. You have some control over how BAD status on input channels can get into SIS modules. Certain input channel parameters and algorithm parameters impact the detection of faults on input channels and whether BAD status becomes available to SIS module logic. Handling BAD status on analog input channels An analog input channel (see page 273) always has BAD status when the measured current is outside the sensor failure limits, 0.78 mA (-20.12%) and 22.66 mA (116.6%). The limits can be exceeded due to faults in the transmitter, field wiring, or the Logic Solver. You can also cause the channel to have BAD status when the current reaches a value inside the sensor failure limits. Changing the "Enable NAMUR alarming" channel parameter to True enables NAMUR limit detection, which results in BAD status being applied when the current is greater than 21.0 mA (106.25%) or less than 3.6 mA (-2.5%) for four consecutive seconds. When the channel value exceeds the channel’s configured "Analog over range pct" or "Analog under range pct," high-limited or low-limited status is applied to the channel. The SOP8 parameter in the Analog Input (LSAI) algorithm has a “BAD if Limited” option. When the LSAI algorithm’s referenced input channel has high or low limited status, the algorithm applies BAD status to its PV and OUT parameters if the option is enabled. The HART Analog Input channel’s (see page 275) HART related error parameters allow you to select which HART diagnostic conditions detected in the HART transmitter or by the Logic Solver cause BAD status to be integrated with the analog value on the channel (the "BAD if Limited" channel parameter). The default value of these parameters is to ignore all HART diagnostic errors, meaning the presence of an error condition does not cause BAD status on the channel. If you deselect “Ignore Field Device Malfunction,” for example, the channel has BAD status if the transmitter reports a device malfunction, allowing this HART diagnostic to be integrated with your SIS module logic.

7.7 Configuring the Logic Solver's response to detected faults Handling BAD status on digital input channels Faults detected on digital input channels (see page 279) by the Logic Solver result in BAD status on the channel. The Logic Solver detects open and short circuits in field wiring if line fault detection has been enabled on the channel using the "Detect open and short circuit" parameter. When line fault detection is enabled, you must use a NAMUR sensor or install end of line resistors in series and parallel. An open or short detected through line fault detection results in BAD status on the channel. Line fault detection is required when the field switch is normally open, that is, when the channel is On to indicate a demand. Line fault detection is recommended when the field switch is normally closed, that is, when the channel is Off to indicate a demand. If an open circuit occurs in the field wiring, it is a safe failure whether or not line fault detection has been enabled. But a short in the field can be a dangerous failure and be undetected, unless line fault is enabled, in which case the channel has BAD status.

7.7 Configuring the Logic Solver's response to detected faults Using BAD Status in SIS Modules Two algorithms are available in SIS modules to manipulate output channels: the Digital Output (LSDO (see page 150)) algorithm and the Digital Valve Controller (LSDVC (see page 157)) algorithm. Each has a CASND input parameter whose value is the commanded state for the output channel, which is connected from upstream logic in the SIS module. When the status of CASND changes to BAD, the algorithm starts a timer whose value is stored in the FTMR (fault detection timer) parameter. If and when the timer reaches the configured FTIM (fault detection delay) value, the algorithm enters the fault state if theFOP2 (Enable detection based on CASND status) option is enabled. The algorithm drives the output channel Off when it is in the fault state. SIS algorithms have a predetermined way of propagating the status of input parameters to output parameters. Faults detected on input channels cause BAD status to reach output algorithms in SIS modules depending on the configuration of other algorithms in the SIS module. The configured value of FTIM in output algorithms determines how long status can be BAD before the output algorithm initiates a trip. The default value is 300 seconds, which gives enough time for operators to bypass a BAD input and take corrective action before a trip is initiated. Use an appropriate value for FTIM in each output algorithm. Some SIFs (see page 6) can tolerate a high number corresponding to your allowed repair time, while other SIFs may require a low number of just a few seconds. The following figure illustrates the use of common SIS algorithms to create shutdown logic in an SIS module. The status on the output parameter of the input algorithms, LSAI and LSDI, is the status of the referenced input channel. The Analog Voter (LSAVTR (see page 82)) and Digital Voter (LSDVTR (see page 169)) algorithms propagate BAD status on input parameters selectively. For example, if a single input of a 1oo2 (1 out of 2) or 2oo3 (2 out of 3) voter algorithm has BAD status, OUT continues to have GOOD status because there are enough good inputs for a real process demand to cause a trip. However, if a single input of a 1oo1 or 2oo2 voter algorithm has BAD status, its OUT has BAD status. If a CSn (input Cause n) input of a Cause and Effect Matrix (LSCEM (see page 113)) algorithm has BAD status, all EFFn (output Effect n) outputs associated with that input have BAD status. LSAVTR, LSDVTR, and LSCEM algorithms have a configurable SOPT parameter, which impacts how the algorithms determine the value of their output parameter(s) based on the status of their inputs. These algorithms determine the status of their output parameter(s) by fixed status propagation logic unique to the algorithm and independent of the SOPT parameter. This assures that if BAD status is capable of preventing a process demand from causing a trip, BAD status propagates to the output algorithm(s). Refer to the LSAVTR, LSDVTR, and LSCEM algorithm documentation for more detail on the impact of the SOPT parameter in these algorithms.

7.7 Configuring the Logic Solver's response to detected faults
7.7.2 Detecting faults on output channels Faults detected by the Logic Solver on output channels (see page 280) can originate in field devices, field wiring, or the Logic Solver output circuitry. As with input channels, the Logic Solver responds to faults on output channels by integrating BAD status with the channel value and annunciating the fault. A fault on an output channel does not prevent the output from being de-energized if there is a demand to trip on that channel. Suppose a Digital Output channel is stuck On due to a fault in the output circuitry. When SIS module logic detects a process demand to trip and the LSDO algorithm drives the channel Off, power remains On as a result of the fault. However, the Logic Solver reads back the output as still being On and initiates a reset, which opens the master power switch and de-energizes all output channels on the Logic Solver. When the "Detect open and short circuit" parameter on Digital Output channels is True (the default value), the Logic Solver detects and annunciates stuck On conditions by means of periodic pulse testing. In this way a failed unit can be replaced before a demand occurs, thereby avoiding a trip on all output channels. The "Detect open and short circuit" parameter should remain configured as True unless the final element cannot tolerate the 1 millisecond Off pulse during each 50 millisecond period. If the Logic Solver detects an open or short in field wiring or the output circuitry, it integrates a special status with the channel value called BAD SensorFailure LowLimited. Output algorithms detect this status on the referenced output channel and optionally drive the output channel Off. If the “Enable detection based on output channel status” option is set in the algorithm’s FOP3 parameter, the algorithm enters the fault state and drives the channel Off immediately upon detection. The FTIM value is not used in this case. An open or short in field wiring implies the final element is in the de-energized state. Therefore the default value for the FOP3 parameter drives the channel Off when an open or short is detected. In order to keep the channel Off after it is driven Off, an operator reset must be required somewhere. The reset can be on the final element itself, in the output algorithm, or in the upstream LSCEM algorithm. The following figure shows an example of using an LSCEM algorithm for latching an output Off.
314
OW331_47
7.8 Choosing the Logic Solver scan rate The CS3 input of the LSCEM (see page 113) algorithm has a value of 1 when neither output algorithm is in the fault state. FSTAT is normally an internal parameter, but in this example, it is exposed as an output parameter on the LSDO and LSDVC algorithms and connected to an LSNOR algorithm. If either output algorithm detects an open or short on its referenced channel, a trip occurs on EFF1 of the LSCEM algorithm and both output algorithms drive their outputs Off (because CASND becomes 0). The algorithm that detected the open or short had already driven its output Off. The outputs remain Off until an operator reset is done on EFF1 by changing RST1 of the LSCEM algorithm to True. The fault state condition clears when a Digital Output channel is driven Off because the diagnostic no longer detects the condition. The same is true for a HART Two-state Output channel when OFCUR is “0 milliamps.” This technique applies to the case where a coordinated trip of multiple final elements is required when any of the final elements involved in an interlock becomes de-energized due to an open or short. If you want to drive Off only the output with the open or short, use a separate LSCEM Effect output for each output algorithm and connect FSTAT into a separate Cause input. In some applications it may not be desirable to drive an output Off when an open or short is detected. For example, you may want the final element to become energized without operator intervention whenever an intermittent short clears. In this case, disable the FOP3 parameter in the output algorithm.
7.8
Choosing the Logic Solver scan rate The default scan rate (see page 267) for SIS module execution in the Logic Solver is 50 milliseconds. You can change the scan rate to 100, 150, or 200 milliseconds from the SLS properties dialog in Ovation Explorer. Increasing the Logic Solver scan rate value impacts the execution rate of SIS modules. But diagnostic cycle times in the Logic Solver remain constant, with the exception of the main processor comparison diagnostic, which is a function of SIS module scan rate. The recommended scan rate to use whenever possible is 50 milliseconds. This scan rate minimizes the input to output response time. The only reason to change the scan rate beyond the default 50 milliseconds is if the Logic Solver is not able to execute the SIS module or modules at the configured scan rate.
7.9
Loading to a running process If you anticipate a need to make online changes to SIS module logic, that is, to load Logic Solvers that are protecting a running process, you should ensure the load does not disrupt the process. Locking a Logic Solver prevents it from being loaded. Locking also prevents a user-initiated Logic Solver switchover. To be able to lock or unlock a Logic Solver you must have the SIS Can Load privilege. A Logic Solver must be unlocked before you can load to it (see page 285). If you attempt to load a locked Logic Solver, you are given the opportunity to unlock the Logic Solver and continue.

7.10 Restarting a Logic Solver after a power failure
7.10 Restarting a Logic Solver after a power failure A restart occurs after power is restored to a Logic Solver that had a running configuration prior to losing power for less than 10 days. During a restart the Logic Solver reapplies the last loaded configuration and restores parameters that had been saved to non-volatile memory. At the time power is lost, outputs of the Logic Solver are de-energized, which should result in the same output state as after the original load. After a restart the goal is to retain the same process state that occurred as a result of the power failure, yet to restore the parameter values that were saved to non-volatile memory, which are more current than the last loaded values.
7.11 Proof testing the Logic Solver Logic Solvers must be proof tested periodically to ensure there are no dangerous faults present that are not being detected by continuous runtime diagnostics. A manual proof test for a Logic Solver is initiated from the Developer Studio and causes the Logic Solver to go through reset and power-up testing. Proof testing of Logic Solvers can also be done automatically. Immediately following successful power-up testing, there are no known dangerous faults present. Choose the proof test interval for a Logic Solver based on the associated SIF requiring the shortest proof test period to achieve the required probability of dangerous failure for its Logic Solver subsystem. The Logic Solver proof test timer automatically counts the number of days since the last reset occurred. The Logic Solver configuration dialog in Developer Studio has a Proof Testing tab for entering the required proof testing interval and a reminder time value. See Logic Solver configuration for information about the fields in this tab (see page 268).

OW331_47
7.11 Proof testing the Logic Solver The Logic Solver provides an alert when the number of days since the last reset exceeds the configured time. A reminder alert occurs a configured number of days before the “exceeds” alert to assist maintenance personnel in the planning of manual tests. The proof test timer for a redundant Logic Solver indicates the number of days since the last reset of the Active unit, which always occurs earlier than the last reset of the Standby.
7.11.1 Automatic proof testing Automatic proof testing is available for redundant Logic Solvers only. The Proof Testing tab of the Logic Solver configuration dialog has an “Enable automatic proof test to run at reminder time” check box (this check box is grayed-out for simplex Logic Solvers). When checked, the Logic Solver performs the proof test when the number of days since the last reset reaches the configured time. The test begins five minutes after the Logic Solver sets the reminder alert. In this case the reminder alert informs the operator that a test will occur soon so that the "Partner Not Available" alerts can be ignored after the test begins. At the time of automatic proof test:
The Active Logic Solver starts the test by initiating a switchover to the Standby Logic Solver. If the Standby Logic Solver is not available, the Active Logic Solver tries again in five minutes.
After switchover, the Standby Logic Solver becomes Active and the new Standby Logic Solver goes through reset and begins power-up testing. There is no adverse impact to the running process.
The new Active Logic Solver still has a proof test due, so it waits for its partner to become available then initiates a switchover. When the partner has become the Active Logic Solver, the new Standby Logic Solver goes through reset and power-up testing.
7.11.2 Manual proof testing The following procedure should be used for manual proof testing of the Logic Solver. Simplex Logic Solver 1. Initiating a manual reset on a simplex Logic Solver results in all outputs being de-energized. If you must proof test a simplex Logic Solver online, you need to temporarily bypass or block final elements and provide manual supervision. 2. The Logic Solver must be Unlocked to initiate a manual reset. Select the Logic Solver under SIS Network in the Developer Studio. Right-click on the Logic Solver and select Unlock. Click Confirm on the SIS Write confirmation dialog. 3. Right-click on the Logic Solver and select Reboot. The Restart Wizard appears. Select Force Restart Active from the options in the Restart Wizard window (see page 307). Clicking Confirm on the confirmation dialog results in all outputs being de-energized. 4.

The format also contains information that identifies the item (sheet, library, macro) to the system and to the user. By placing this information in the frame, you do not have to enter it every time you create a new item. The Control Builder provides an approved frame or template file, called the frame.svg file, which is shipped with the standard release of the Ovation system. All of the elements of the frame are defined in the frame.svg file. You many want to customize a frame in order to more easily identify SIS control sheets. The SIS Data Server, Logic Solver, and Control Module are available as Document Values under the Draw menu. Use the following procedure to create a SIS custom frame (Frame.svg) in the unit's ControlFunctions directory. 1. Copy the default frame (C:\Ovation\CtrlBldr\Frame.svg) into the ControlFunctions Directory. 2. Add a [Document Value] for cb-sis-server in the custom frame (Frame.svg). You may wish to add items for the Logic Solver and/or the Control Module at this time. 3. Recompile all the control sheets. 4. Load the Logic Solvers and control sheets.

7.13 Upgrading SIS firmware
7.13 Upgrading SIS firmware Future releases of Ovation software will potentially include updated firmware for the SIS components. It may not be necessary to upgrade the firmware in SIS hardware components when the remainder of the Ovation system is upgraded to a new release. But if a new SIS firmware revision has desired features or corrects a specific issue, you can upgrade to the new revision by installing files from an Ovation workstation to flash memory in the SIS component. The following topics provide upgrade procedures:
To initially load or upgrade an SIS Data Server (see page 319).
To upgrade an SIS Logic Solver (see page 320).
7.13.1 To initially load or upgrade an SIS Data Server When you first receive an SIS Data Server, you must perform an initial load of the firmware. Subsequent loads of the SIS Data Server are considered to be upgrades. Emerson provides firmware for the SIS components in your Ovation system. Firmware for the upgrade to your SIS Data Server consists of four Hex files and one UDF file. Use the following procedure to initially load or upgrade your SIS Data Server. 1. Retrieve the new SIS Data Server firmware from the path: Ovation\SIS\firmware\OvSisSDSFirmware.zip 2. Unzip the files and store the four Hex files and one UDF file in an area where they can be easily accessed; (for example, C:\temp\sis) 3. Open a Command Prompt window and go to Ovation\OvationBase. 4. Enter the following: OvSisCtlUpgConsole -n where: = name or IP address of SIS Data Server to be loaded or upgraded = absolute path to Hex and UDF files (for example, OvSisCtlUpgConsole 192.168.1.1 C:\temp\sis\InstallCtlR_MD.udf)

7.13.2 To upgrade an SIS Logic Solver Emerson provides firmware for the SIS components in your Ovation system. Use the following procedure to upgrade your SIS Logic Solver (SLS): Note: The typical upgrade time for a single Logic Solver is about eight minutes. If during the upgrade process there is a network failure, or the workstation which is hosting the upgrade application fails, you can restart the upgrade. To do so, repeat the procedure starting at Step 4. 1. Retrieve the new Logic Solver firmware package. It consists of four files:
1340.idf
IO_Compatibility.csv
SLSApp.hex
SLSBoot.hex 2. Store the four files in an area where they can be easily accessed; (for example, C:\temp\sis) 3. Clear the target SLS in the Developer Studio (see page 263). 4. Clear the Ovation Controller to which the target Logic Solver is assigned. 5. Run the upgrade application: Ovation.Sis.Sls.Upgrade.Console.exe [SDS ip address/hostname] [logic solver number] [logic solver redundant] [full path to idf file] where: [SDS ip address/hostname] = IP address or hostname of the SIS Data Server which is supervising the Logic Solver that you are upgrading. [logic solver number] = Number (1-32) of the physical Logic Solver that you are upgrading (this is not the carrier slot number). [logic solver redundant] = Flag indicating whether the target Logic Solver is in a redundant configuration. Accepted values of this attribute are true or false. [full path to idf file] = Fully qualified file name of the .idf file which is part of the firmware package, (for example, d:\sls-firmware\v.10.3\1340.idf 6. Confirm that you want to proceed with the upgrade by entering y when prompted.
