*1 Special register SD1506 can be specified as a dummy device.
Function
Calculates the manipulated value (MV) by performing input addition processing from the input value (E1 = MV) of the device
specified in . Turns ON/OFF the device specified in
S1
The ON/OFF time is a value on the assumption that the time specified as the control output cycle (CTDUTY) is 100%.
The ON/OFF time is changed in each execution cycle.
Also performs the change rate, upper/lower limiter and reset windup of the calculated manipulated value (MV) at this time.
