Modbus RTU Disconnected - khalil - 22.03.2023
hello dears,
I have few devices connected on Modbus 485 Port.
while this is the second time that all devices disconnected suddenly, but didn't reconnect until I repot the SL!
Why could this issue happened and how to avoid it?

Hard to say, check if anything else didn't try to use same port.

its only for Modbus RTU via profiles no scripts
I think to make a script to restart the modbus port if this issue happened. but this is not the optimal solution

But you should try to find the core for the issue, first is to check for any error logs when this happens.
