GuardLogix to GE 90/70 Communication Bridge

[ThePEee 0]

Hi to all, new to this forum.

I have some projects to upgrade existing control systems from GE Fanuc 90/70 series controllers to Allen Bradley GuardLogix (or ControlLogix). The projects must be managed in phases, where through a portion of the project, the existing GE and new Allen Bradley controllers will need to co-exist, sharing each other's connected I/O and processor status for program operation. I've reviewed some options for a communication card that would reside in the Allen Bradley modular rack, but concerned that effort to use an Ethernet based TCP/IP protocol is impractical due to GE's proprietary Ethernet protocol of the time period (circa 1992 for these controllers). Modbus serial is a possibility, but wanted to exhaust Ethernet options first. I have a SCADA connection in place now, using OPC server connection to GE and Allen Bradley processors in the plant. I would like something more robust with distinct traffic between controllers. I am also open to using a dedicated PC with network cards and drivers to connect directly to PLCs, but would prefer a third party packaged system to avoid development time and OPC type connections.

Anyone have any ideas or tested solutions for this particular application? I'm all ears! Thanks in advance.

hello, try to check MV156-EGD this is from prosoft which is a reliable partner of Rockwell Automation. it a GE Fanuc to Controllogix data exchange over ethernet.

Cheers,
