DIASYS-IDOL++ Function Blocks This chapter explains basic concept and outlines of DIASYS-IDOL++ function blocks.

1.1

Basic Concept DIASYS-IDOL++ function blocks are the control logic description language for the plant control unit accumulated with MHI’s ample know-how on Plant Control. Application of DIASYS-IDOL++ function blocks can realize the plant automation that is satisfactory to users in all aspects such as reliability, performance, extensibility, etc. The basic concept of DIASYS-IDOL++ function blocks is shown below.

 High reliability based on our great achievement  Easy maintenance  Excellent control arithmetic function to flexibly cope with continous control and sequence conrol  Easy online logic monitoring and tuning

(1)

High reliability High reliability resulted from strict quality-control structure and is proved by numerous achievement.

(2)

Easy maintenance Control-arithmetic programing becomes available by drawing the control logic used on design drawings traditionally, on CRT of EMS. Special programing knowledge is not necessary.

(3)

Excellent control arithmetic function High-level control arithmetic is realized with the combination of 180 types of control arithmetic elements. Furhtermore, the continous and sequence controls are available for handling on the same logic. All the parts are prepared for the use in the control system such as Operator Station display method, data logging function of alarm detection logic, etc. and can be expressed on the same sheet.

(4)

Easy tuning Online tuning can be performed with monitoring control logic-arithmetic status on CRT screens.

1.1 Basic Concept 1-1

TAS71-R001E

1 1.2

Control Logic DIASYS-IDOL++ function blocks are the programing language which describes arithmetic logic in the Multiple Process Station (MPS). The logic is described on the maintenance tool and the program completed by this is executed in the Multiple Process Station (MPS). This chapter explains the logic control configuration in DIASYS-IDOL++. EMS Logic description and tuning are executed by using DIASYS-IDOL++ function block.

Grammar of DIASYS-IDOL++ Function Blocks This chapter explains the grammar of DIASYS-IDOL++ function blocks which are necessary for logic-sheet drawing. In other words, the following is the explanation about logic elements (I/O elements/arithmetic elements), connection lines, arrows and data delivery between logic sheets.

2.1

Logic Sheet and Drawing Elements A logic sheet screen has the following configuration. As the basic drawing layout, the signal that is input from the input elements on the left side of the screen is connected with a line and an arrrow for the alignement whose arithmetic result is output from the right side. If complex connection lines are allowed, input elements can be laid out at any location.

Fig. 2.1-1 Logic sheet screen

2.2

Function Block Classification There are five types of function blocks as follows. • Input/Output blocks • Control arithmetic blocks • Operator Station blocks • Data logging block • System blocks • External Communication Blocks

2.2.1 Input/Output Blocks Input/output blocks are elements for input or output of Process Station I/O signals and other logic sheet signals onto the logic sheet screens. There are eight types of them as follows.

For example, analog input signals and digital input signals in Process Station can be captured into logic with ‘Analog Input (AI)’ and ‘Digital Input (DI)’ of input/output elements. In the same manner, the output of analog and digital signals to ‘Analog Output (AO)’ and ‘Digital Output (DO)’ by logic can output them as Process Station output signals.

2.2 Function Block Classification 2-2

TAS71-R001E

2.2.2 Control Arithmetic Blocks

2

Control arithmetic blocks have calculation functions to execute control logic. They execute the calculation designated by each block according to the signal values connected to the arithmetic element, in order to output the result. Control logic are described with combination of control arithmetic blocks. Refer to “Appendix-1. Function Block Description” for the detailed functions of the elements.

2.2.3 Operator Station Blocks Operator station blocks are used for drawing system diagrams such as process flow, plant flow, etc. They are prepared with control and monitoring blocks for plant configuration devices, e.g. indicators (digital indicators/firm-shape analog indicators), auxilliaries (tank level/pumps). Refer to “DIASYS-IDOL++ Graphic Parts Reference Guide (TAS71-R006E)” for the detailed functions of each block.

2.2.4 Data Logging Blocks Data logging blocks are used for warning judgement and printing-report data collection included in the data logger function. Refer to “DIASYS-IDOL++ Graphic Parts Reference Guide (TAS71-R006E)” for the detailed functions of each block.

2.2.5 System Blocks These are blocks for analog I/O, digital I/O, and integer value I/O used by the system in Process Station. They are not used in normal logic but only for Process Station design. Refer to “Appendix-1. Function Block Description” for the detailed functions of the elements.

2.2.6 External Communication Blocks The external communication blocks support the communications with networks outside Netmation, such as IEC60870 communication. For details about the features of each block, see “Appendix-1 Explanation of Functional Blocks”.

2.2 Function Block Classification 2-3

2.2.7 Tag Names/Signal Names Tag and signal names can be set up in function blocks. They are set up when the logic sheet is drawn. Please refer to “DIASYS Netmation® LogicCreator (FLIPPER) User’s Guide (TAS71-U004E)” for the detailed explanation.

2.2.8 Parameter

2

Parameters can be defined with external input and fixed values. Principally, those for function blocks with possibility to become variable in control can perform external input. However, there are function blocks such as ‘Polyline Function (FX)’ with many parameters and special-structured parameters like loop names of ‘Loop Arithmetic Call (CLL)’, which can only set up with fixed-value definition. Function block codes are used as parameters if there are external input corresponding to the parameters. If there are not any input, they will perform arithmetic using the interior parameter of the function blocks. Parameters can be shown as below for the same function block.

2.3

Connection Lines

2.3.1 What Connection Lines are In the logic sheet screen, the data captured by I/O blocks such as ‘Analog Input (AI)’ and ‘Digital Input (DI)’ are connected to arithmetic elements with connection lines. Control logic is formed by input of arithmetic-element output signals to another arithmetic elements by connection lines. Moreover, input of arithmetic-element output signals to output elements like ‘Analog Output (AO)’ and ‘Digital Output (DO)’ with connection lines can output command values and control arithmetic results from the MPS. In short, the connection lines show the data flow.

(1)

Types of Connection Lines DIASYS-IDOL++can handle mixture of analog data such as temperature/pressure and digital data such as ON/OFF and open/close in one logic sheet. These two data types are drawn with the distinguished connection lines. There is also an I/O connection line for the data handling integers (4 byte integer numbers) Since there are three types of connection lines prepared for the element menu of the logic-sheet creation screen, they are used according to the data types.

Bold line for analog data Thin line for digital data Bold line for integer data

Fig. 2.3-1 Connection line types

2.3 Connection Lines 2-6

TAS71-R001E

(2)

Connection Error for Lines

2

It will be an error if lines that do not conform are tried for connection because the data types are determined for the connection according to the logic element type.

Though an ‘AI’ element outputs analog data, they are connected with the digital-data line.

Though a ‘S R’’ element inputs digital data from No.1&2 inputs, the analog data line is connected with No. 2 inpout.

2.3 Connection Lines 2-7

2.4

I/O Signal Distinction

2.4.1 Function Blocks with Multiple Input Some function blocks are input with multiple signals. Those blocks are classified into two types according to the input signal handling. (1)

Those that handle all input signals in the same manner as far as the meaning is concerned

e.g.)AND, OR, ADD, etc. (2) Whose input signals have different meanings in terms of function-block arithmetic processing. e.g.)SSR, DLT, PI, etc. In item (2), logic should be described by distinguishing I/O signals.

2.4.2 Display Format of Input Signals Input signals with different meaning have codes according to the meaning. They can be distinguished by displaying the code on the signal line when the logic is described. Please refer to “Appendix-2. Function Blocks Description” for the details.

Fig. 2.4-1 Example of Input 1 description in PI element

2.4 I/O Signal Distinction 2-8

TAS71-R001E

Also, arrows can be used to distinguish the input. However, this method can be applied to four input types at the maximum. The same arrows are displayed from the input 5 onward as those starting from input 1. The following are the shapes of four arrrows.

Input 1 Input 2 Input 3 Input 4

Data between Sheets/Data inside Sheet

2.5.1 Data between Logic Sheet (CED/CEA/CEI) Because control logic processed in MPS are created separately in multiple logic sheet, data delivery between the logic sheet is necessary. Those elements are‘data between logic sheet’.

2.5.2 Data inside Logic Sheet (CID)

2

Data inside the logic sheet are I/O elements for data delivery inside different logic sheet. They are used to avoid the logic from becoming hard to see because the connection is complicated for the direct connection in the sheet. CID’ elements are used to link signal data in the same logic sheet in the Process Station.

Macro Elements

2.6.1 What a Macro Element is Macro elements are functions to handle the logic combined with multiple standard arithmetic elements in the same way as ordinary arithmetic elements by registering them as one elements.

(1)

Usage of Macro Elements Diagrams can be created efficienty by collecting the parts with many same logics in the diagram such as auxillary-unit startup and shutdown logics, as one macro element.

Macro Element Creation

2

When logics are created with macro elements, it is necessary to register those created. Drawing and registration of macro elements are performed in the same VISIO based screen as the logic sheet. Please refer to “DIASYS Netmation® LogicCreator (FLIPPER) User’s Guide (TAS71-U004E)” for the detailed procedure. Here, the following shows the first registration screen drawn with macro elements by LogicCreator (FLIPPER).

(3)

Parameter Setting Concerning the macro elements created in (2), the properties such as Name, Name1, Tag, etc. are to be set up in the same manner as that of other function blocks. Please refer to “DIASYS Netmation® LogicCreator (FLIPPER) User’s Guide (TAS71-U004E)” for the detailed procedure.

2.7

Quality Information Added to Function Blocks

(1)

What Quality Information is DIASYS-IDOL++ function blocks have various quality data (the data set and input signal abnormality) other than the process data as additional information. For instance, logic data have the quality as attached information and are transmitted via the function blocks to change the quality of data display in Operator Station. The transmission rules and the designation if the transmission is peformed or not are different depending on the property of the logic composed of function blocks. Therefore, arithmetic-element calculation methods etc. are previously defined using quality judgement, element output in case of abnormality, and quality-abnormality signals for the input. The quality information is displayed when the property is opened during OPS logic-status monitoring.

Example) T

FX

Input signal quality on the selected side is transmitted to the output.

Quality-Information Types

Data quality has a structure to distinguish if the following six items and their factors are occurring in their functions or transmitted from input signals. Table 2.7-1 List of quality information Quality factor Range-over upper limit Range-over lower limit Data-access unavailability Block-arithmetic error

Scan exclusion Data set

(3)

Contents AI signal range is over the upper limit. AI signal range is over the lower limit. The access is not performed normally to I/O controller or I/O module. The communication is stopped for communication data between systems. The calculation is not performed normally following the arithmetic specification. (Zero division, negative square-root extraction, etc.) The scan exclusion is performed manually. The data set is performed manually.

Thinking on Quality Transmission Input signal quality is transmitted to the output quality for arithmetic performance of function blocks. The action is based on the following rules. Table 2.7-2 List of quality transmission Items Operator Station display and printing reports Digital input signal Function blocks with clear I/O relation

The same number of multiple input Signal selection

Blocks performed with data operation

Rules To display and print the process status on the Operator Station screen or the reports, the colors and the display format should be modified according the quality. The input signal quality should be all transmitted for the Operator Station interface blocks. Regarding the digital signal input to function blocks, it is not targeted as the quality transmission principally. The quality is transmitted for those whose output are decided by one input signal such as line-shape conversion, polyline function, etc. On the other hand, the quality transmission is not performed for those whose calculation results are output for multiple input signals, e.g. proportional integral, analog memory, etc. When multiple input such as addition, multiplication, etc. have the same meaning, the quality OR is transmitted for each input signal. Regarding the function blocks that select one signal from multiple input such analog switching/high value selection, etc., the calculation is implemented ignoring the quality and the selected signal quality is transmitted to the output. Regarding the function blocks performed with scan exclusion and data set in the data operation functions, only the quality for scan exclusion and data set is output regardless of the I/O signal quality.

Standard Method for Logic Description This chapter explains the standard description method for the logic which is often used to create logic.

Conversion of Engineering Value for Process Input Signals

Analog Signal Range All analog signals are handled by the numeric values modified to engineering values in function blocks.

Table 4.1-1 Analog signal range Input type Analog input

Analog output

4.2

Signal range 1 to 5V/4 to 20mA

Conversion method with logic Output of the value converted to the engineering value range from AI function block in Logic Thermocouple The value read into the input element AI is the value converted to the temperature engineering value. Measuring The value read by the input element AI is the valoue temperature resistance converted to the temperature engineering value. 1 to 5V/4 to 20mA In Logic, the value is input corresponding to the engineering value range for AO function block.

Tracking Processing

4.2.1 What Tracking is Tracking is a function to adjust the element arithmetic output to a certain value by temporarily stopping the ordinary arithmetic function, an element’s original feature, through trackingcommand reception. There are two types of tracking as follows. • Direct tracking of input signals for ordinary arithmetic • Apart from iput signals for ordinary arithmetic, tracking of signals input for tracking.

4.1 Conversion of Engineering Value for Process Input Signals 4-1

TAS71-R001E

(1)

Tracking to Input Signals For instance, in the case of ‘Primary Delay (LAG)’ element, the input signal is output as it is by the output signal cancelling the primary delay arithmetic when the tracking signal is turned ON (1). There are similar arithmetic elements such as ‘Primary Progress/Delay(LLG)’,‘Lamp (RMP)', and 'Change-Rate Restriction Unit (RLT)’.

4

In the case of getting rid of unnecessary effects from initial-value data, tracking is performed at the start of control logic arithmetic.

The output signal is performed with traking to the input signal.

Tracking to Tracking Data For ‘Proportional Integral(CSR)’ elements, output signals stop the proportional integral arithmetic to output the tracking data when the tracking signal is turned ON (1). Here, the example is explained using the control valves for proportional integral arithmetic. If the valve is switched to automatic mode to start the operation after manual operation with opening by the discretion degree, the valve opening degree is changed dramatically without starting the proportional integral arithmetic from the suitable value for the degree. To prevent that, it is necessary to have the output value of proportional integral arithmetic trackd to the valve opening degree when the valve is in the manual mode. The tracking function is required to those elements that have arithmetic functions with internal ingral values. There are similar arithmetic elements such as ‘Proportional Integral(QSR)’ and When the target operation has both automatic and manual modes, the tracking should be performed when it is in the manual mode.

However, the elements with internal sizing-value arithmetic function such as ‘Primary Delay (LAG)’ and ‘Proportional Integral(PI)’, have some cases that they cannot start the right arithmetic because of the sizing value instability at arithmetic start. Furthermore, there are other cases the elements that change internal memory for the output only when the input signals are modified such as ‘Set/Reset (SSR/SRR)’, cannot output the right output value due to the instability of internal memory at the time of arithmetic start. Therefore, necessary initialization processing should be performed in the ‘Initializing...’ status at Process-Station startup. Regarding the output from the control logic arithmetic to the outside, there is not output of analog and digital signals from the Multiple Process Station because the

4.3.1 Initialization of Analog Signals The following are the funtion blocks with initialization processing such as ‘Primary Delay (LAG)’. • ‘Differential(D)’ • ‘Primary Delay (LAG)’ • ‘Primary Progress/Primary Delay (LLG)’ • ‘Proportional Integral(CSR)’ • ‘Proportional Integral(QSR)’ • ‘Analog Memory(AM)’ • ‘Change-Rate Restriction Unit (RLT)’

4.3.2 Initialization of Digital Signals There are cases that digital signals need initialization as follows. Whose output values are determined by change details of input signals such as ‘Set/Reset (SSR/ SRR)’ and self-maintenance circuit combined with elements. Whose output values are determined by continuation time of input signals such as ‘Timer (OND/ OFD)’. Initialization methods are different depending on the logic combination. Here, one example of the initialization is explained about ‘Set/Reset’.

The following is an example of build-in loop plates on the logic sheet.

Fig. 4.4-1 Example of control logic with loop plates

4.4.1 Examples of Writing the Operation Logic for Loop Plates This section describes the loop plates that are actually displayed on the operator station. Use LoopPlateCreator (SCALLOP) to define the settings for each loop plate, such as the characters to be displayed and the color of the characters. Then use LogicCreator (FLIPPER) to set the input and output and connect the settings with other function blocks. This section describes the settints to be maded in LogicCreator (FLIPPER). For details about the settings to be made in LoopPlateCreator (SCALLOP), see “DIASYS Netmation® LoopPlateCreator (SCALLOP) User’s Guide (TAS71-U007)”. There are six types of loop plates as standard. The Main PB & Sub PBs type and the Multiple Analog Set & Sub PBs type are described here.

(1)

Main PB & Sub PBs The Main PB & Sub PBs loop plate is used to operate auxiliary devices (pumps, valves) and to select modes. Figure 4.4-2 shows an examle of the Main PB & Sub PBs loop plate displayed on the operator station.

In the main PB area of the Main PB & Sub PBs loop plate, up to five operations and displays can be performed. In the sub PB area, up to ten operations and displays can be performed. However, TAGGING is fixed and its usage is limited. For details about the configuration of the Main PB & Sub PBs loop plate, see Chapter 2 “Specifications of Loop Plates” in “DIASYS Netmation® LoopPlateCreator (SCALLOP) User’s Guide (TAS71-U007)”. In the example of Figure 4.4-2, two elements are set in the main PB area and seven elements are set in the sub PB area for operation and display. Figure 4.4-3 shows an example operation monitoring logic of the Main PB & Sub PBs loop plate described in Figure 4.4-2.

TAS71-R001E

(1)

‘Proportional Integral (PI)’ The integral value will continue the integral to the upper or lower limit regardless of the proportion even when the output reaches the upper or lower limit. When enough time has passed after the output is reached to the upper or lower limit, the output stays at the upper or lower limit unless the input becomes the negative or positive. Even when the input is constantly fluctuating, the output does not move further than the upper or lower limit with this element being the upper/ lower limit, as long as the code of the input value does not change.

5

Usage:Used often for wide-open valves at normal operation (such as spray valves used only for emergency or high-pressure escape valves, etc.)

(2)

‘Proportional Integral with Upper/Lower Limit Input (PIQ)’ The integral value will stop the integral as soon as the output reaches the upper or lower limit. Even if enough time has passed after the output reaches the upper or lower limit, the output changes with the proportion when the input positive or negative value is changed. When the input is constantly fluctuatiing, the output is also changing around the upper or lower limit with this element being the upper or lower limit. Usage:Used often for operation-end used in the medium open degree at normal operation. Please refer to “Appendix-2 Description of Logic Function Blocks” for the behaviour of’Proportional Integral(PI)’ and’Proportional Integral with Upper/Lower Limit Input(PIQ)’.

Creating New Scripts (1)

Open the LogicCreator (FLIPPER) and then stencil (IdolPlus_MACRO.vss) that stores the Macro element by [File] - [Stencil] - [Open Stencil] - [IdolPlus_MACRO.vss].

(2)

Drop the script call element in the Macro stencil on the sheet and modify the size if necessary.

(3)

Connect signals to this script call element. In this example, connect 4 analog inputs, 2 digital inputs, 4 analog outputs, and 2 digital outputs to the element. Up to 20 input signals and 20 output signals can be connected to a script call element. Table 6.1-1 shows the default settings for input and output. Connectors do not need to be connected at this point. Start ScriptCreator (Squid) and declare variable names to change the names on LogicCreator (FLIPPER) to the variable names declared in ScriptCreator (Squid). For example, declaring X1 as “Pressure” changes X1 in LogicCreator (FLIPPER) to “Pressure”. Note that integer input and output is not prepared by default. To use integer input and output, declare integer as the argument type (Iin, Iout, Ioutn).

6.5 Script Syntax 6-13

TAS71-R001E

6.5.3 Variables Both stored variables and local variables support the int, float, and double types. Values can be substituted for variables at declaration. For stored variables, initial values are substituted and they are calculated only for the first time. For local variables, values are substituted every cycle. Example of declaring a variable: floatZERO=0.0; Stored variables also support the intn, floatn, and doublen types without tracking.

Description A branch instruction that occurs based on a specific condition. A branch instruction that executes one of two sections of code based on a specific condition. Repeats a section of code for a specified number of times. Evaluates a predefined condition and repeats a section of code while the predefined condition is satisfied. Executes a section of code and evaluates a predefined condition, then repeats the section of code while the predefined condition is satisfied. Transfers execution to some other statement. Exits a loop or switch. Returns to the beginning of a loop. Returns to the call source.

6.6.1 Propagating quality The quality of data is represented by Q (variable name) and the quality of input can be propagated to output. Example:Q(Y1)=Q(X1); Propagate the quality of input X1 to Y1. For details about quality information, see Section 2.7 “Quality Information Added to Function Blocks”.
