CompactLogix/ControlLogix PLC Peer-to-Peer

EtherNet IP Gateway

Siemens S7-1200 PN EtherNet/IPTM Software

Download the EtherNet/IP Function Blocks to communicate with Rockwell ControlLogix PLC's. A demonstration mode is not supported for the S7-1200 PN Co-ordinator Function Block.

Develop your communication strategy and purchase your runtime licence when you are satisfied with the solution. 


This is a software solution which utilises the existing Ethernet capabilities of the PLC systems you wish to connect. No hardware gateway is required.

The Manual and instruction videos provide the guidance to easily connect a Siemens S7-1200 PLC with an integrated CPU PN Ethernet port to a ControlLogix PLC using EtherNet/IP.
