10.6.3 Remote PAUSE
Remote PAUSE refers to the function that performs PAUSE function to the QnACPU from
an external source while the CPU module RUN/STOP key switch is set to the RUN
position.
The PAUSE function stops a CPU module operation while retaining the ON/OFF status of
all outputs (Y).
(1) Application of remote PAUSE
This function can be used to retain the output (Y) with ON status even if the CPU
module is in STOP due to process control.
(2) Methods for remote PAUSE
The following two methods are available for performing remote PAUSE.
(a) Method using a remote PAUSE contact
The remote PAUSE contact is set in the PLC system in the parameter mode of
GPP function.
The settable device range is from input X0 to 1FFF.
1) When the scan END processing is performed with both the remote PAUSE
contact and the PAUSE enable flag (SM206) are ON, the PAUSE status
contact (SM204) turns ON.
When performing up to the END instruction of the scan following the scan in
which the PAUSE status contact turned ON, the PAUSE state is established
and operation is stopped.
2) When turning the remote PAUSE contact OFF or turning SM206 OFF with
GPP function, the PAUSE status is reset and the sequence program
operation is again performed from step 0.
REMARK
