I am working on setting up a network with a few Allen Bradley PLCs and an ABB DCS. We are using the Allen Bradley Ethernet protocol. The AB PLCs are being supplied by a third party who I requested provide me with a list of the all the available points for monitoring. All of the vendors except one have provided a list with addresses in the format N17:0/0. The one vendor that was different provided addresses in the format W200. ABB responded to me with a comment that this last vendor's data was not useable in that format because the OPC server they are using is only capable of reading the Allen Bradley addresses in first format (I assume the raw data). In order to read this other format they would have to use a second OPC server. This is new territory for me and I don't fully understand why this vendor’s data would be in a different format. ABB seems to think that this vendor was supplying its own OPC server on the PLC end. Does this make sense and can anyone clarify this for me. What do I need to tell this vendor in order for him to provide the addresses in the correct format? Thanks.
