11 PROCESS CONTROL INSTRUCTIONS
11.2 I/O Control Instructions
This instruction calculates the manipulated value (MV) from the input value (E1=MV) in the device specified by (s1), and
stores the result in the device specified by (d1). The instruction also performs variation rate & upper/lower limiter, reset
windup, and output conversion processing of the calculated manipulated value (MV).
The following is the processing block diagram of the S.OUT1 instruction. (The numbers (1) to (6) in the diagram indicate the
order of the processing.)
