Relationship between remote operation and RUN/STOP status
of the CPU module
(1) Relationship between remote operation and RUN/STOP status of the CPU
module
The following table lists the operating status of the CPU module according to the combination of remote operation
and RUN/STOP status of the CPU module.
RUN/STOP
status
RUN
STOP
*1
When performing the operation using a RUN contact, "RUN-PAUSE contact" must be set in the PLC system tab of the
PLC parameter dialog box.
*2
When performing the operation using a PAUSE contact, "RUN-PAUSE contact" must be set in the PLC system tab of the
PLC parameter dialog box.
In addition, the PAUSE enable coil (SM206) must be turned on.
*3
The "Allow" checkbox for the remote RESET operation must be selected in the PLC system tab of the PLC parameter
dialog box.
*4
The remote RESET and remote latch clear operations are enabled if the CPU module status is changed to STOP by the
remote STOP operation.
*5
The status includes a case where the CPU module is stopped due to an error.
(2) Remote operations from a single programming tool
When remote operations are performed from a single programming tool, the operating status of the CPU module
will be the status of the last remote operation performed.
(3) Remote operations from multiple programming tools
Any remote operation from other programming tools via other stations cannot be performed to the CPU module
where remote operations are being performed from a programming tool connected. To perform any remote
operations from other programming tools, cancel the remote operation by performing the remote RUN operation
from the same programming tool that is performing the current remote operation.
For example, even if the remote STOP or RUN operation is performed from the other programming tool to the
CPU module where the remote PAUSE operation has been performed by the programming tool connected, the
CPU module remains in the PAUSE status. Once after the remote operation is canceled by performing the remote
RUN operation from the same programming tool that is performing the remote PAUSE operation, remote
operations from the other programming tool will be enabled.
