Modbus communication lost
#5
First, check Modbus error log. There's a slight chance that some incorrect profile definition causes Modbus mapper to crash. Have you tried rebooting LM to see if Modbus starts working?

If daemon is running then disconnect both lines and connect only one device and see if it works.

You can also disable both Modbus ports, connect RS485 1/2 together and run self test to check that ports are working: https://forum.logicmachine.net/showthrea...2#pid21682
