I suspect you have a new LOGO! 8.3 module.

For this you need the current V2.1.8 version of the CMR as the connection became encypted

Thanks for your help!

I did the update, but the led is still red. Any other ideas?

What is printed in the diagbuf?

Did you set up secure LOGO 8.3 communication at monitoring?

Where i setting the communication secure.?

I meant, that you are using communication profile LOGO! BM 8.3 and higher, which you seem to do according to the diagbuf

As it says the certificate validataion fails.

Please set the time of the CMR to the actual.

Simply go on System-->SystemTme and use apply PC time. Maybe certificate validation fails because of this.

Works!!! There was a problem with the system time!

Thanks a lot!

Hi, how did you make it work?

I have the same problem, I tried to use PC time but it still does not work.
