Vision PLC with Red Lion Ether-Trak Modules


Recommended Posts

  • MVP 2023

I've never done Red Lion, but I have used other Modbus I/O modules.  The trickiest part is building a stable RS-485 network.  The Unitronics recommendations on the location of terminating resistors doesn't always work, as cable length can have a lot of effect on signal levels.  If you connect your modules and you can't see them try turning on and off the terminator at the PLC and at the end of the run.
