The General-Purpose Calculation Blocks (CALCU, CALCU-C) are used when defining arbitrary calculation algorithms.
General-Purpose Calculation Blocks (CALCU, CALCU-C) ▼ Connection
The General-Purpose Calculation Block (CALCU) is a function block that executes pre-defined arbitrary calculation algorithms. Calculation algorithms are defined using the general-purpose calculation expression description language. The Calculation Block with String I/O (CALCU-C) has the same function as the General-Purpose Calculation Block (CALCU), but the former has I/O terminals that can handle string data and a part of the I/O data is used only for string data. Here is a function block diagram of the General-Purpose Calculation Blocks (CALCU, CALCU-C).

Functions of General-Purpose Calculation Blocks (CALCU, CALCU-C) The CALCU and CALCU-C blocks perform input processing, calculation processing, output processing, and alarm processing. The processing timings available for the CALCU and CALCU-C blocks are a periodic startup and a one-shot startup. Selections available for the scan period used to execute a periodic startup include the basic scan period, the medium-speed scan period (*1), and the high-speed scan period. *1:
SEE ALSO
The medium-speed scan period can only be used for the FFCS series, KFCS2, KFCS, LFCS2, and LFCS.

Input Processing of General-Purpose Calculation Blocks (CALCU, CALCU-C) when a Calculation Input Value Error is Detected The CALCU and CALCU-C blocks perform special input processing when an abnormal calculation input value is detected.
Exact Totalization Pulse Train Input of General-Purpose Calculation Blocks (CALCU, CALCU-C) When the input signal conversion is specified with [Exact Totalization Pulse Train Input], the totalization can use the calculation output value (CPV).
Calculation Processing of General-Purpose Calculation Blocks (CALCU, CALCU-C) The CALCU and CALCU-C blocks perform computation using arbitrarily defined calculation algorithms and their setup parameters.
Alarm Processing Specific to General-Purpose Calculation Blocks (CALCU, CALCU-C) The “calculation error alarm check,” which is one of the alarm checks performed by the CALCU and CALCU-C blocks, is specific to these two function blocks.
Calculation Output Value Range limit of General-Purpose Calculation Blocks (CALCU, CALCU-C) The calculation output value (CPV) can be limited in range between SL-(SH-SL) and SH (*1). *1:
SL= CPV scale low limit; SH= CPV scale high limit
In/Out Data Normalization of General-Purpose Calculation Blocks (CALCU, CALCU-C): FFCS Series/KFCS2/LFCS2 In CENTUM-XL system, the In/Out data of general-purpose calculation blocks are normalized values. In CENTUM VP system, the In/Out data of general-purpose calculation blocks can be either normalized values or engineering unit data values according to the designation on the builder. Designating to use the normalized In/Out data of general-purpose calculation blocks can retain consistency when migrating a CENTUM-XL calculations to CENTUM VP system.
Input Processing when a Calculation Input Value Error is Detected ▼ Calculated
Input Value Error Detected
Define the calculation value error detection condition of the CALCU and CALCU-C blocks and the data status of the calculation output value (CPV) when an error is detected i n “Calculated input value error detected” of Function Block Detail Builder. By default, this setting is set as “0: Non-Detecting Type.” In connection with these settings, a method by which the data status (IOP, IOP-, OOP, NRDY) related to the process control input/output generated with the calculation input values (RV, RV n) is communicated to the calculation output value (CPV) will furthermore be determined. The data status of the calculation output values (CPV1 to CPV3) is always NR (normal) regardless of the setting in [Calculated input value error detected] item. Table 1.33-3

The priority order is from RV to RV n (*4).
-: Ignore (don’t care) “RV1 to RV7” means the logic sum of the data statuses from RV1 to RV7. An “NR” entry in the table indicates a condition where the data status is neither BAD nor QST. The IOP and IOP- of a status to be communicated have higher priority. An IOP will be transmitted if an NRDY has been generated for an input value with higher priority, and an IOP has been generated at the same time for an input value with lower priority.
The following processing is performed if the data status of a calculation output value (CPV) becomes a ba d data value (BAD) or a questionable data value (QST) according to the specification of the calculation input value error detection. • If the data status of a calculation output value (CPV) becomes a bad data value (BAD) The calculation processing is aborted, the value immediately before the error is retained and the connected destination of OUT terminal will hold this retained previous value. The previous good CPV is held and accessible from SUB terminal. If CPV overshoot is set to the block, the data from the OUT terminal is not affected by the CPV change caused by main calculation input (RV) abnormality. However, the CPV after overshoot can be accessed using SUB terminal. • If the data status of a calculation output value (CPV) becomes a questionable data value (QST) The calculation input values (RV, RV n) retain the values immediately before the error generation. The calculation processing is continued using these values and the calculation output value (CPV) is updated.
Input Processing for Data Status QST: FFCS Series/KFCS2/LFCS2 For a calculation block input, if its data status is QST, the QST status can be passed to the calculated output value. For passing the QST status, check the option of [Pass calculation block's input QST status to CPV] on [Constant 3] tab of FCS properties sheet. When the option is checked or unchecked, the behaviors of CPV data status vary as follows: Table 1.33-4 CPV

Data for Totalization when Input Signal Conversion is Exact Totalization Pulse Train ▼ Data
Item for Totalization
When the input signal conversion is specified with [Exact Totalization Pulse Train Input], the totalization can use the calculation outut value (CPV) instead of the integration of the calculation input value (RV). [Exact Totalization Pulse Train Input] can be specified on the Function Block Detail builder for the item of [Input Signal Conversion]. Data Item for Totalization: Choose [RV] or [CPV]. The default is [RV]. Moreover, if the [Input Signal Conversion] is specified with another type of conversion, the totalization can only use the calcaulation output [CPV], cannot use the calculation input [RV].
Calculation Algorithm The General-Purpose Calculation Blocks (CALCU, CALCU-C) execute algorithms that are defined using the general-purpose calculation expression description language. The calculation input values, calculated output values and set parameters of the Ge neral-Purpose Calculation Block (CALCU) all use double-precision floating-point data type. The calculation input values (RV4 to RV7) and calculated output values (CPV2, CPV3) of the General-Purpose Calculation Block with String I/O (CALCU-C) all use string data type. When data of other function block is referred or set using element symbols and a description of data items without specifying I/O terminal connections in a calculation expression description, terminal connections of the specified I/O data are performed automatically during compiling. The I/O terminals used here are different from those connected in the Function Block Detail Builder.

The input signals that are directly specified in the calculation expression description become the target of calculation input error detection.
SEE ALSO
For more information about the general-purpose calculation expression description language, refer to: 1.47, "General-Purpose Arithmetic Expressions"
Restriction on the General-Purpose Calculation Blocks (CALCU, CALCU-C) • Up to eight input terminal connections and four output terminal connections can be defined on the Function Block Detail Builder. • Up to 24 input data and 12 output data can be referred or set as the element symbols and data items in a calculation expression. • However, for using alphanumeric strings in CALCU-C, a maximum of 6 character strings and 6 numeric strings can be used. • Data of other FCS cannot be used in an arithmetic/logic calculation expression.
Set Parameters The parameters of the General-Purpose Calculation Blocks (CALCU, CALCU-C) are shown as follows. • Calculation parameters 1 to 4 (P01 to P 04) Engineering unit data values. • Calculation parameters 5 to 8 (P05 to P08) Engineering unit data values in the case of General-Purpose Calculation Block (CALCU). A string data of up to 16 standard-width characters or 8 double-width characters can be used for the General-Purpose Calculation Block with String I/O (CALCU-C).
Computation Error Alarm Check A computation error alarm (CERR) is generated if a calculation error occurs during the processing of a userdefined calculation formula. If a computation error alarm (CERR) is generated, the calculation processing stops and an error message containing an error generation statement number and an error code is output. The error occurrence statement number is set to the data item ERRL, and the previous value is held as the calculated output value (CPV). The ERRL can be accessed from other function block, since it is handled as a parameter. Under this circumstance, the system alarm may occur. However, if the setting item of [Suppress system alarm when CALCU calculation error occurs] is specified on the builder, the system alarm message will not occur. If a computation error occurs, the computation executes again from the beginning of the calculation in the next scan. If the second computation is completed correctly, the computation error alarm (CERR) returns to normal. The value at the error occurrence is held in ERRL. On the builder, if the setting item of [Suppress system alarm when CALCU calculation error occurs] is specified, when the calculation error occurs, the CPV data status will not change to BAD but the alarm status will change to CERR.

system alarm when CALCU calculation error occurs
When running the CALCU or CALCU-C calculations, if a calculation error occurs, a system alarm message will be initiated. However, this message can be suppressed by specifying the setting item of [Suppress system alarm when CALCU calculation error occurs] on the “Constant 3” tab of FCS Properties. By default, this option is not enabled.

CPV Range Limit: FFCS Series/KFCS2/LFCS2 ▼ CPV
range limit
The CPV Range Limit can be applied to limit the calculation output value (CPV) within a specified range. The CPV can be limited in range between SL-(SH-SL) and SH. When CPV is smaller than the low limit of SL-(SH-SL), the low limit will be used. When CPV is greater than the high limit of SH, the high limit will be used. The CPV range limit is different from the PV range limit, only limit the calculation output value (CPV). The limited calculation output value will go through digital filter and used for totalization. The CPV Range Limit functions only when the block mode is AUT. The CPV Range Limit can be specified on Function Block Detail builder. CPV Range Limit: Choose [Valid] or [Invalid]. The default is [Invalid].

Calculation Block In/Out Data Normalization ▼ Normalization
of Input/Output Signal
By designating on the builder, the calculation can be performed using the normalized values for the data connected to the IN terminal, Q01 to Q07 terminals, OUT terminal, J01 to J03 terminals of a general-purpose calculation block and the data set to or referenced by the general-purpose calculation block according to the PV range (SH, SL), SV range (SSH, SSL), MV range (MSH, MSL) of the data. The I/O terminals for numerical data and the numerical variables in the CALCU-C function block are also affected by this feature. The numerical input and output terminals of CALCU-C function block are as follows: • Input Terminals for Numerical Data: IN, Q01 to Q03 • Output Terminals for Numerical Data: OUT, J01 • Numerical variables that referenced or defined by the expressions in the CALCU-C function block
Even though the I/O normalization is specified on the builder, the CENTUM-XL calculation expressions are not free from problems. After the CENTUM-XL migration, the application debugging is necessary.
In Data Normalization The input engineering unit data (RV) of a calculation block can be normalized before used in the calculation. When normalizing the RV, the range of the general-purpose calculation block will be ignored but the range of the block connected to IN terminal or Q01 to Q07 terminal will be used. The normalization is performed with the following formula: RVN = (RV – SLi) / (SHi – SLi) RVN: After normalization RV: Before normalization (Engineering Unit Data) SHi: Scale high-limit of the connected data SLi: Scale low -limit of the connected data For the data item, such as DV or DL, that is differentiated from other data items, the normalization is performed with the following formula: RVN = RV / (SHi – SLi) RVN: RV: SHi: SLi:

Convert Output Data to Engineering Unit Data When outputing the calculated data, the normalized data can be converted to engineering unit data. When converting CPV to an engineering unit data, the range of the CPV will be used. When converting CPV1 to CPV3 and other internal variables to engineering unit data, the ranges of the blocks connected to J01 to J03 terminal will be used. The conversion is performed with the following formula: CPV = CPVN x (SHo – SLo) + SLo CPV: Before normalization (Engineering Unit Data) CPVN: After normalization SHo: Scale high-limit of the connected data (for CPV1 to CPV3 and other internal variables) Scale high-limit of CPV (for CPV) SLo: Scale low-limit of the connected data (for CPV1 to CPV3 and other internal variables) Scale low-limit of CPV (for CPV) For the data item, such as DV or DL, that is differentiated from other data items, the conversion is performed with the following formula: CPV = CPVN x (SHo – SLo) CPV: Before normalization (Engineering Unit Data) CPVN: After normalization SHo: Scale high-limit of the connected data (for CPV1 to CPV3 and other internal variables) Scale high-limit of CPV (for CPV) SLo: Scale low-limit of the connected data (for CPV1 to CPV3 and other internal variables) Scale low-limit of CPV (for CPV) The formulas for normalizing the input data and for converting the output data to engineering unit data in related to ranges are shown in the table below: Table 1.33-7

Designating In/Out Data Normalization Data normalization can be designated for each calculation block on the Function Block Detail Builder of the general-purpose calculation block. Normalization of input/output signal: Select “No” or “Yes” Default: “No” The settings regarding the calculation block in/out data normalization as well as the general-purpose calculation details and function block details can be printed out on the builder and printed out through selfdocumentation.
Regarding DT or NX terminal of BDA-L, BDSET-1L/BDSET-2L Block When a general-purpose calculation block is referencing or setting the data of a DT01 to DT16 or a NX01 to NX16 terminal of a BDA-L, BDSET-1L/BDSET-2L block, the data normalization and the range limitation will be performed according to the range of the data connected to the corresponding J01 to J16 terminal. The data normalization and range limitation according to the range of the data connected to the J01 to J16 terminals are performed only when the connected data is normalizable. When the data connected to the J01 to J16 terminal is changed, CALCU that referencing the previously connected data may become invalid element. In this case, you need to perform the operations for resolving the invalid elements.
Normalizable Data (Data Connection) What data item can be normalized is automatically determined on the control drawing builder. The normalizable data items (Data Connection) are listed below. In this table, the numbers that represent different formulas are the same as in the table of In/Out Data Normalization. • Regulatory Control Blocks Table 1.33-8 Model name

Normalizable Data (Terminal Connection) CPV is normalized or converted according to the range of itself.
SEE ALSO
For more information about terminal connection, refer to: 2.2, “Terminal Connection” in the Function Blocks Overview (IM 33K03E21-50E)
Data That Irrelevant to Data Normalization The following data are irrelevant to data normalization. • Data connected through switch blocks (SW-33, SW-91) • Data connected through inter-station data link block • Data connected through process I/O • Data connected through software I/O • Data connected to SUB terminal • Data connected through sequence connection • Data connected to MI, NB, CR and GM terminals of self-tuning PID controller block (PID-STC) • Data connected to MV1 to MV8 items of a cascade signal distributor block (FOUT) • Data connected to MV, MSH, MSL, MH, ML and RMV items of YS blocks • Data items that indicating the high and low limits (SH/SL/SSH/SSL/MSH/MSL/DSH/DSL/MSH1/MSL1/MSH2/MSL2) If you want to normalize the above data, you can connect the data to a PVI block first and then connect to the calculation block.
CENTUM-XL Compatible Action if CPV is not substituted in Calculation If the normalization of input/output signal is enabled and the CPV is not substituted in the calculation, at the end of the calculation script, CPV=RV will be affixed. In this case, the action will be as follows: CPV: CPV is substituted by RV and output through OUT terminal. digital filter: Activated (*1) totalization: Activated (*1) *1:
In CENTUM-XL, the calculation blocks do not have digital filter and totalization features.
