simultaneously since they are independent.
• When the PIDINIT(P) instruction was used to make initialization, use the PIDCONT(P) instruction to perform
PID operation. To stop and start the PID operation of the specified loop No. and to change the PID control
data, use the PIDSTOP(P) instruction, PIDRUN(P) instruction and PIDPRMW(P) instruction.
