We have a SLC5/05 that's acting as the main MTU for our SCADA system. I need to bring in some data from an AutomationDirect CLICK PLC that supports Modbus/TCP. The data currently will only need to flow one direction: from the CLICK into the SLC5. However, in the future they might ask me to send data back to the CLICK, but it's not something they need right now.
I can modify the program of either PLC to either MSG Read from the SLC, or SEND from the CLICK.
Note that the Serial port of the SLC is already in use by another application, so it's unavailable.
I found some Modbus to AB Gateway devices, but I'm not sure what Ethernet protocol the SLC5/05 uses to send/receive data. I don't think it uses Ethernet/IP like CompactLogix, does it? My version of RSLogix500 does have the EEM instruction, but I don't know if the SLC supports it. Currently all data is sent or received with the MSG instruction.
I also have a Kinco HMI available, which is supposed to speak several different protocols, but again I'm not sure which protocol the SLC speaks.
Thanks for your advice.
