M580 to M580 - PLC Communications/Data Exchange

[Taffy123]

Hi all,

Pretty new to using Schneider currently I'm trying to get communications working between two M580 PLCs.

One of the M580s is just being used as a glorified RIO with no real code inside of it, just passing all IO back to the mainM580 processor (this was done due to hardware constraints by the client).

The Main M580 PLC processor is a BMEP583020 and we have a NOC0301 that is connected to the RIO M580 CPU ethernet ports. The RIO M580 is a BMEP583020.

The code has been written attempting to use READ_REMOTE to try and read data between each of these PLCs but I am constantly getting an error which is just a generic error (1100). I'm using the ADDMX block to set the address for the READ_REMOTE block - which is 0.3.0{10.80.64.139} for the Main PLC trying to read the RIO PLC data from the NOC unit.

The issue is being unfamiliar with the Schneider, and having not written the code, I'm not even sure the READ_REMOTE is the correct way to facilitate communications and if it is what's going wrong.

A few considerations:

1. Is the data dictionary enabled and operating in the target PLC?
2. Is the name of the target variable or variables added as a string and is identical to the variable in the target PLC.  As a note, I use the same variable name in the source PLC but add a reference or comment to indicate the variable is sourced or used in another PLC.
3. Please make sure the address is entered as a string for the ADDMX block.
4. Please also check that the network is OK and that you can ping the target the PLC when connected to the service port of the NOC module.
