I've got to replace a Fanuc Micro IC620MDR014D 14 point PLC that has an "intermittent" run/program switch. I want to download the logic from the old and reload into a new PLC, but have never seen one of these little jewels. I have Proficy ME 7.0, but am unsure how to make the comms connection or if I can even use Proficy. It appears the brick has an Ethernet connector for comms. The original programming ladder diagrams state it was written with Versa Pro, but no other information is available. Any suggestions? Thanks, Tom
