[FUNCTION]
■PIDSTOP, PIDSTOPP
• Stops the PID operation for the loop number designated by (n). The loop stopped by the PIDSTOP(P) instruction does not
resume PID operation even if the PIDINIT(P) instruction is executed.
• Retains the operation data during the stop.
■PIDRUN, PIDRUNP
• Starts the PID operation of the loop No. specified by (n). This instruction is designed to re-execute PID operation of the loop
No. that has stopped with the PIDSTOP(P) instruction.
• This instruction will be ignored if the instruction is executed for the loop No. that is currently running PID operation.
[OPERATION ERRORS]
An operation error will occur and the error flag (SM0) will be turned ON in the following cases.
Error code Description
4100 When the loop number designated by (n) does not exist.
4100 When (n) is outside the range 1 to 8 (Basic model QCPU).
4100 When (n) is any other than 1 to 32. (High Performance model QCPU, Redundant CPU, Universal model QCPU, LCPU, and QnACPU)
4103 When the PIDINIT(P) and PIDCONT(P) instructions have not been executed before execution of the PIDSTOP(P) instruction.
4103 When the PIDINIT(P) and PIDCONT(P) instructions have not been executed before execution of the PIDRUN(P) instruction.
