How to use Powerlink G3 as a modbus gateway

How to use Powerlink G3 as a modbus gateway.    
One can setup a Powerlink NF2000G3 or NF3000G3 on an ethernet network for Modbus over TCP/Ip communications.  One can then wire up to 8 other devices by RS-485 communications from the 2-wire RS-485 terminals in the Powerlink G3.    Commands for the modbus devices can be sent over TCP/IP via the Powerlink G3 Controller.

Product Line:
Powerlink Lighting Control
NF2000G3, NF3000G3, NF3000G3C

Commercial or Instituitional Building

This feature allows devices to be accessed via modbus TCP/IP when then otherwise would require a direct modbus communication line back to the BAS network.

First setup the Powerlink G3 Controller for Modbus TCP/IP communcations.   Set the modbus registers explained in the attached instruction bulletin to put the controller into Modbus Passthrough Mode.  
Note that if the controller is an NF3000G3C with a C-bus network, then Modbus Passthrough Mode is not available.
