Serial communication connection between the JX inverter and PLC:
The JX inverter will be controlled entirely by MODBUS commands over the RS485 serial
communication link (to the CP1L PLC), so no ‘hard’ I/O wiring is required. Your Lean
Automation Kit will have been supplied with a communication cable which fits between the
RJ45 (‘Ethernet-style’) socket on the front of the JX and the screw terminals of the CP1W-
CIF11 RS422/485 communications option module, fitted in the right-hand slot of the CP1L
PLC.
1. Insert the RJ45 connector end into the front of the JX inverter (located behind the
rubber flap)
2. Connect the GREEN wire into the first terminal of the CP1W-CIF11 communications
option module, marked ‘RDA-‘
3. Connect the WHITE/BLUE wire into the second terminal of the CP1W-CIF11
communications option module, marked ‘RDB+ ‘
4. Remove the CP1W-CIF11 module from the PLC; set the DIP switches (at the rear
of the unit) according to the diagram below:
