The slots to the left of the CPU are permitted.
Connect the Ethernet cable to the CP. You will find the pinout of the interface in the section Technical
Turn on the power supply.
The remaining steps in commissioning involve
downloading the STEP 7 project data.
The STEP 7 project data of the CP is transferred when you
load to the station. To load the station, connect the engineer-
ing station on which the project data is located to the Ethernet
interface of the CPU.
You will find more detailed information on loading in the follow-
ing sections of the STEP 7 information system:
• "Loading project data"
• "Using online and diagnostics functions"
Close the front covers of the module and keep
them closed during operation.
To ensure interference-free operation, keep the front panels of the module closed during
operation.
