6.6.5 Relationship of remote operation and CPU's RUN/STOP status
(1) Relationship of the Remote Operation and CPU module Switch
The CPU module operation status is as shown in Table6.13 with the combination of
remote operations to RUN/STOP switch.
* 1 : When performing the operation with RUN contact, "RUN-PAUSE contact" must be set at the "PLC
system" tab screen in the "(PLC) Parameter" dialog box.
* 2 : When performing the operation with PAUSE contact, "RUN-PAUSE contact" must be set at the
"PLC system" tab screen in the "(PLC) Parameter" dialog box. In addition, the remote PAUSE
enable coil (SM206) must be set ON.
* 3 : "Remote reset enable" must be set at the "PLC system" tab screen in the "(PLC) Parameter"
dialog box.
* 4 : The remote RESET and remote latch clear operations are enabled if the CPU module is changed
into the STOP status by the remote STOP operation.
* 5 : This includes a situation where the CPU module is stopped due to error.
(2) Remote Operations from the Same GX Developers
When remote operations are performed from the same GX Developer, the status of
the remote operation that is executed last will be effective.
(3) Remote Operations from Multiple GX Developers
Remote operations from multiple GX Developers via other stations cannot be
performed to the CPU module where remote operations from single GX Developer
are being performed.
(a) Remote RUN executed by GX Developer that is performing remote operation
When performing remote operation from another GX Developer, execute remote
RUN using the GX Developer that is performing remote operation and cancel the
remote operation.
For example, a remote PAUSE operation is being performed by one
GX Developer, the PAUSE status will remain active even if a remote STOP/
remote RUN operation is attempted by another GX Developer.
When a remote RUN operation is performed by the GX Developer that is
performing a remote PAUSE operation, and then that remote operation is
cancelled, a new remote operation can be performed by another GX Developer.
