Correction Operation
The following FBs perform operation processing such as broken line correction, standard filter, engineering value conversion,
temperature/pressure correction, and summation.
■Function Generator
Function block symbol Processing details
M+P_FG Outputs (OUT_) values according to the function generator pattern that consists of SN break points
with regard to the input (IN).
■Inverse Function Generator
Function block symbol Processing details
M+P_IFG Outputs (OUT_) values according to the function generator pattern that consists of SN break points
with regard to the input (IN).
■Standard Filter (moving average)
Function block symbol Processing details
M+P_FLT Outputs (OUT_) the average value of SN pieces of data of the input (IN) collected the at data
collection interval ST.
■Engineering Value Conversion
Function block symbol Processing details
M+P_ENG Converts a value (%) of the input (IN) in percentage into an engineering value such as temperature
and pressure and outputs (OUT_) the result.
■Engineering Value Inverse Conversion
Function block symbol Processing details
M+P_IENG Converts an input engineering value (IN) such as temperature and pressure into a value in
percentage (%) and outputs (OUT_) the result.
■Temperature/Pressure Correction
Function block symbol Processing details
M+P_TPC Executes temperature/pressure correction (or either of temperature correction or pressure
correction) to the input (IN) of the differential pressure (%) and outputs (OUT_) the result.
■Summation
Function block symbol Processing details
M+P_SUM When the integration start signal (START) is TRUE, this function block performs integration
processing to the input (IN) and outputs (OUT_) the result.
■Summation (Internal Integer Integration)
Function block symbol Processing details
M+P_SUM2_ When the integration start signal (START) is TRUE, this function block performs integration
processing to the input (IN) and outputs the result.
Internal integration for the integral part is executed with signed 32-bit integers.
■Range Conversion
Function block symbol Processing details
M+P_RANGE_ Executes range conversion to the input (IN) and outputs (OUT_) the result.
