Remote Pause; Executing Method - Mitsubishi Electric MELSEC iQ-R Series User Manual

16.2

Remote PAUSE

This function externally changes the CPU module status to PAUSE with the RUN/STOP/RESET switch of the CPU module set
to RUN. Use this in a process control and other situations to keep the CPU module status in RUN even when changing the
status of the output (Y) to STOP.

Executing method

The following methods are available to execute remote PAUSE:
Using a contact
Set PAUSE contact in "RUN-PAUSE Contact Setting". ( Page 222 Setting RUN-PAUSE Contacts)
When the END processing for the scan where the PAUSE contact is turned on is executed, SM204 (PAUSE contact) turns on.
When the CPU module executes until the END instruction for the scan next to that where the PAUSE contact is turned on, its
status changes to PAUSE, and the operation stops. When the PAUSE contact is turned off, the CPU module exits the PAUSE
status and resumes the program operation from the step 0.

RUN/PAUSE state
In redundant mode, when the backup mode setting is enabled in the CPU parameter, both systems may be
recognized as being mismatched in the system consistency check even if the remote operation is
simultaneously performed on the systems. This is because an operating status mismatch occurs depending
on the timing.
Using an engineering tool
Perform remote PAUSE with the remote operation of the engineering tool. ( GX Works3 Operating Manual)
The operation method in a redundant system is the same as that for remote RUN/STOP. ( Page 220 Using an
engineering tool)
By an external device using SLMP
Perform remote PAUSE with the SLMP command. ( SLMP Reference Manual)

(2) SM204 turns on when the END processing for the
scan where the set PAUSE contact is turned on is
executed.
(3) When the CPU module executes until the END
instruction for the scan next to that where the
PAUSE contact is turned on, its status changes to
PAUSE, and the operation stops.
