Read the system manual "S7-1200 Programmable Controller"
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
Appendix).

"S7-1200 Programmable Controller".
Make sure that the power supply is turned off when installing/uninstalling the devices.
The STEP -7 project data of the CP is stored on the local CPU. If there is a fault on the
