I have a applicataion where we are repalcing an existing SLC 5/05 PLC with a CompactLogix L43. The existing system has SLC Remote IO racks, connected with a 1747-SN on the PLC and and a 1747-ASB on the remote IO.
The preference for the new system is to reuse the existing remote IO racks, to save wiring, cost etc etc
My question is what are the options for connecting this to the CompactLogix L43?
The L43 needs 2 Ethernet/IP modules (1768-ENBT) for connecting to other systems.
From what I can see, there is no DeviceNet adapter for the SLC remote IO. There is a ControlNet adapter available but this would need one of the 2 communications slots on the L43. Is there an Ethernet adapter availabe? Should I look at a serial connection?
