Hello,
I am using a Compactlogix 5380 PLC and need to read values from a few existing PLC 5s, other Compactlogix PLCss, and a few Controllogix PLCs. It will be difficult to add each device to my PLC's I/O tree so I wanted to use message instructions and type in the correct path but I am confused on how to do this. I don't quite understand the numbers involved with the path but I have an idea. Everything will be over ethernet IP so I believe all my paths need to start as 2, (I.P. of desired PLC to read) . Following that to read from the control logix it would be (slot number of the Ethernet card) , (Slot number of plc). To read from a compactlogix plc I don't believe I need any numbers following the I.P address, and to read from the PLC5 I'm not sure what I need.
I know this question is detailed, but if anyone could explain the number path requirements and what each number means for a Contrologix PLC, a Compactlogix PLC, and a PLC 5 that would be very appreciated.
