Processing the "STS" Operation
When the "STS" operation is executed, the programmable controller goes into the STOP mode
immediately. Program processing is terminated at this point.
To return the PLC to RUN mode:
•
In safety mode you can only do this manually using the RUN/STOP switch
•
In test mode you can do this either manually using the RUN/STOP switch or on a programmer
using the programmer function "PLC Start".
Note
In safety mode a STOP initiated by the "STS" operation can only be cancelled
manually by operating the two RUN/STOP switches. A STOP initiated by the "STS"
operation is regarded as a safety stop in safety mode.
A STOP initiated by the "STS" operation has the same status in safety mode as a
STOP produced by the RUN/STOP switches.
