  Hi @alydersen, it is hard to tell what's wrong without the access to the setup. Would it be possible to arrange SSH access to the PLC? We can go over the details via email: support@unipi.technology Best regards, Martin

  I assume that this problem has now been solved, based on your responses in other topics? It's hard to see the connections when they overlaid on top of each other like that.

  @sidoor It might work but it always depends on in what environment the installation is done. You can just cut the RS45 connectors and do the wiring in the standardized clamps

  @christophebler Ok, than the serial line works well. But I still recommend using our opensource image because the parameters that can be set using the github version is limited and might cause some troubles which are fixed in the opensource image. Byt the way, what do you want to do by 'Set Adress to 0 and rebooted both devices'? You can set address only at the slave which is the xS50 and if you set it to 0, than the SW configuration is used (address 15, 19200bps, no parity) and you are opening different device... Address 0 is not allowed on Modbus, thus the behavior like I described.

  @SorakCz In case of TCP Modbus than yes, just need to take care of the software part. Sorry for the inconveniences but a few changes in the FW can generate too much questions so I cannot give you any estimated time right now. It can be week but also four...
