RS Networx is a software which is used to create network files like controlnet or devicenet.These network files are used in a PLC program file(*.ACD).This network file then act as a bridge between the PLC and the various IO cards used with the PLC system.Using this network file,network configuration can be done.

RS Networs is a software to configure and communicate with
various allen bradely PLC's and compatible field devices
like VFD's,flex input outputs, intelligent limit switches
etc.
