Note:
For service purposes, you can read out the
cause of the operating status from the diagnos-
tics buffer of the CP. To do this, the CP needs to
be changed from STOP to RUN using the mode
selector.
Controlling the mode
There are different ways in which you can control the mode of the CP 443-5 Extended, as
follows:
●
Mode selector
●
STEP 7 special diagnostics configuration software
To control the CP mode from STEP 7, the mode selector must be set to RUN.
Mode selector
With the mode selector, you can set the following modes:
●
Change from STOP to RUN:
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
