Controlling the mode

The CP loads configured and/or downloaded data into the work memory and then changes
to RUN mode.
• Change from RUN to STOP:
The CP changes to STOP with the following response:
– Established connections (FDL connections, configured, and unconfigured S7
connections) are terminated
– DP slaves are taken out of data transfer
– Data record routing is deactivated
– In STOP mode, configuring and performing diagnostics on the CP remain possible
– In STOP mode, the time of day continues to be forwarded
