Connection with modbus lost

Ignition
1

Hello!

I’ve been having troubles with modbus connection. Ignition gets disconnected from the PLC. The connection is through modbus and the only way I have to restore the connection is restarting the Ignition service. This happens since I installed Ignition 7.3.

Here are the logs:

How can I fix this?

Thanks for your help!

The error you posted doesn’t have anything to do with Modbus, it’s your OPC-UA client connection going down…

Are you connected to the Ignition OPC-UA server or a third-part server? Can you export your logs from the log console (logs.bin.gz) and send it to support?

The problem was I had installed Modbus and Modbus v2 at the same time. I uninstalled the old modbus module and now all is working without modbus problems
