(c) Example of PID control program after PID auto-tuning
The program example for PID auto-tuning is illustrated as Figure 15.27.
[Figure 15.27 Example program of PID control after auto-tuning]
1) Devices used
It is always on, so it readily operates once PLC is RUN.
It starts operation of CH0 of Slot 1 A/D input module.
It starts operation of CH0 of Slot 2 D/A output module.
PV entered to A/D input module.
MV entered to D/A output module.
Device to which PV is entered for LOOP 0 auto-tuning
Device to which auto-tuning MV of LOOP 0 is output.
Junction that is on once auto-tuning is complete.
Junction that is on once auto-tuning has an error.
Min. MV of auto-tuning designated in parameter.
Device to which PV is entered for Loop 0 PID control
Device to which MV of loop 0 PID control is output.
