■Loop selector
Instruction symbol Processing details
S.SEL Outputs the value selected by the selection signal from the input data in automatic mode, and
outputs the manipulated value (MV) in the loop tag memory in manual mode.
■Bumpless transfer
Instruction symbol Processing details
S.BUMP Gradually brings the output value (BW) closer to the output set value (E1) from the output control
value (E2) when the mode switching signal (e1) changes from manual to automatic.
■Analog memory
Instruction symbol Processing details
S.AMR Increases or decreases the output value (BW) at a fixed rate.
Correction operation instructions
■Function generator
Instruction symbol Processing details
S.FG Outputs the input data values according to the specified function generator pattern.
■Inverse function generator
Instruction symbol Processing details
S.IFG Outputs the input data values according to the specified inverse function generator pattern.
■Standard filter
Instruction symbol Processing details
S.FLT Outputs the mean (average) value of the 'n' pieces of data collected at the specified data collection
intervals (ST).
■Integration
Instruction symbol Processing details
S.SUM Integrates the input data, and outputs the operation result.
■Temperature/pressure correction
Instruction symbol Processing details
S.TPC Performs temperature/pressure correction processing to the input data.
■Engineering value transformation
Instruction symbol Processing details
S.ENG Performs engineering value transformation processing to the input data.
■Engineering value inverse transformation
Instruction symbol Processing details
S.IENG Performs engineering value inverse transformation processing to the input data.
Arithmetic operation instructions
■Addition
Instruction symbol Processing details
S.ADD Adds input data with a coefficient.
■Subtraction
Instruction symbol Processing details
S.SUB Subtracts input data with a coefficient.
