I have an application where I'm using an Allen Bradley CompactLogix plc that has to read registers in multiple GE Fanuc 90-30 plcs. The GE plcs talk to each other via a 'Genius' bus and communicate through an Ethernet hub to an HMI display. Any suggestions on what I need to do/get to enable communication between the AB plc and the GE plcs? NOTE: the cpu in the GE plcs is a 364
