I have been using the module for a long time with the logo 8.2 that worked perfectly. Since I installed the logo 8.3 I had to update the CMR firmware which is fine and that also works however I can't get a connection anymore when the CMR is connected (currently password off). If I pull the cable out it works. I have set up a network setup but how do I connect the CMR which is not in the list? Thanks in advance Attachment Snipaste_2022-03-14_20-41-58.png (562 Downloads)

You must the CMR say in the CMR configuration that the CMR connected to the LOGO! 8.3 and their IP address. And also you have more to configure. See attachment. Attachment Industrial Ethernet LOGO!

"For information on this, refer to section General functions of the WBW (Page60)" So I have to be able to stop the CMR communication online without pulling out any cables. Thanks Koen

You do not see that you have stopped the CMR. If you forget this, you will not receive notifications or you can have the CMR Auto started every 2 hours, for example? Thanks BR Koen

I am not aware that the LOGO! the CMR can start or stop. Likewise, I am not aware that there is a setting in the CMR which allows a start/stop in a certain period of time.
