PI Interface to 800xA (AFWsurrogate)
Hi All
We have established communication between ABB OPC server and PI Server , This was existing install base where ABB replaced Ivensys Foxbro system to ABB 800xA System.
Once we have established communication communication to PI Server , PI Server is reading Digital signal as True and False. Now PI is requesting the data to be come in format of 0 and 1.
Is there any setting possible in AFWsurrogate to send the data in 0 and 1 format.
Regards
Rajeesh

No. The source OPC server's item format is delivered.
*Strongly* urge PI to accept source format instead of trying to convert it, eg using Property Translation.

1. I have posted about this multiple times ... Do *not* use OPC-DA to connect to PI. Use the PI OPC HDA Interface and connect to the Basic History Server. This is much more efficient and will allow you to recover past data whenever the interface needs to be stopped or restarted. Talk to your customer about getting OSI to exchange the interface license. There is typically no cost.
2. PI records "Digital" values ( including Multi-State devices link Stop/Forward/Reverse ) using "Digital State" tags. These translate numeric values into Strings. Digital state tags can read any digital input and translate to True/false or on/off etc. This is a job for your PI maintainer. It's not an 800xA problem.
