Module replacement 
Module replacement   
The STEP 7 project data of the CP is stored on the local CPU. If there is a fault on the 
device, this allows simple replacement of this communications module without needing to 
load the project data to the station again. 
When the station starts up again, the new CP reads the project data from the CPU. 
If you replace a module, remember to take the SIM card from the old module and insert it in 
the new CP.

Prior to installation, connecting up and commissioning, read the relevant sections in the 
system manual "S7-1200 Programmable Controller" (refer to the documentation in the

When installing and connecting up, keep to the procedures described in the system manual 
"S7-1200 Programmable Controller". 
Make sure that the power supply is turned off when installing/uninstalling the devices.
