3.3 Controlling the operating mode
You have the option of changing the mode of the CP between RUN and STOP
using the STEP 7 / NCM S7 configuration software (PLC > Accessible Nodes).
Procedure
S Switch from STOP to RUN:
The CP reads the configured and/or downloaded data into the work memory
and then changes to the RUN mode.
S Switch from RUN to STOP:
The CP changes to STOP. Established connections (ISO-on-TCP, TCP, UDP
connections) are terminated (transitional phase with LED display “STOPPING”);
The reaction is as follows in STOP:
− The communications connections mentioned above are terminated;
− The configuration and diagnostics of the CP is possible (system connections
for configuration, diagnostics, and PG channel routing are retained);
− HTTP access is possible
− The routing function is active
− The time of day is not forwarded
− PROFINET IO is disabled.
