RUN/STOP
switch
RUN
STOP
1 When performing the operation with remote RUN contact, "RUN-PAUSE contact" must be
set in the parameter mode PLC system setting.
2 When performing the operation with remote PAUSE contact, "RUN-PAUSE contact" must
be set in the parameter mode PLC system setting. In addition, the remote PAUSE enable
coil (SM206) must be set ON.
3 "Remote reset enable" must be set in the parameter mode PLC system setting.
4 RESET or LATCH CLEAR can be performed if the Basic model QCPU changed to the
STOP state from a remote operation.
5 This includes a situation where the Basic model QCPU 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
While a remote operation is being performed by one GX Developer, another
remote operation cannot be performed by another GX Developer.
After a remote operation that is being performed by one GX Developer is
cancelled, a new remote operation can be performed by another GX Developer.
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.
