I have a SLC 5/04 and I want to see if it is possible to set up a Read MSG with a plc with RS5000 through Data Highway Plus.
I have upgraded a SLC 5/04 to an L71 processor. I had all my integration done between the original PLC through Data Highway as a read MSG. I have been trying with not much success at getting the SLCs to read the L71. I can get the L71 to read and write to the SLCs through the RS5000 software. Is it possible for RS500 to read RS5000 through DH? If so what do I need to set up?
You would need a DH+ interface on the L71. Are we to assume that you have DH+ connectivity to the SLC already? You would use the 1756-UM514 comms manual to setup the routing tables for the SLC to use

Crisis, necessity, change
It is possible for AB SLC controller to read/write data located on Controllogix controller thru DH+ network. To do this, you will need DH+ card (1756-DHRIO) installed at Controllogix chassis, then one the port connected to daisy chain DH+ network to SLC.
At SLC side you will need to setup MSG instruction to read data/write on Controllogix side the same way as to read/write data to PLC-5 controller.
At Controllogix side, you will need to configure port of DHRIO card that you connect to DH+ network as a DH+ port.
then you also need to configure PLC5/SLC Mapping on the menu : Logic - Mapp PLC/SLC message:
Hope this will be helpful, let me know if you need more help
