Also there should be a difference between the ST module and the HF module. The onlyreasonI can imagine is to remember the station name. I you use profinet topology a MMC is not needed, right? This two types we use: 6ES7151-3AA23-0AB0 ET200S, IM151-3 PN ST INTERFACEMODULE 6ES7151-3BA23-0AB0 ET200S, IM151-3 PN HF INTERFACEMODULE Thanks! Nick

The older interface modules needed an MMC to save the Device Name. Best regards, Wizard

For example I have one CPU and 6 ET200S modules with exactly the same in/output modules. In your document is said the following: "Replacement without PG is supported, Profinet conformance" This is only working if you make a topology, right? Also when you first power up your system all modules are empty (no IP and name) you need to adress them with primary setup tool, right? Thanks in advance! Nick

Hello Nick, Yes, or you can in Step 7 go to PLC -> Edit ethernet node Best regards, Wizard
