The Modbus protocol only allows one master, which already exists. If I add another master to the same bus, I expect communication collisions. I want to prevent that.
Instead of a sniffer, it could be an option to add an "bus free function" to your script. For the second master(=VISU) I need a poll intervall of 60sec.
