I have an existing mixed-device 485 modbus network, onto which a CompactLogix L23E is to be added. The network is a 2-wire setup, but all the wiring diagrams I've found for the L23E have indicated the need for additional wires, strangely resembling RS-232.
I've seen dozens of mentions on the net that the serial port on the L23E is Modbus capable (via logic) and supports DH-485, but can't get to the How of this puzzle.
