The AW-70 OPC Client is available and it puts the OPC in I/A Series blocks.
The other alternative is to purchase Application Object Services and use it
in an AW to create Shared Variables with the famous 3 part name. You would
then store the OPC data in the A:O.A.

Subject: Getting OPC data into the I/A
Awhile back I inquired about methods of getting OPC data into an I/A
system. I
got several good responses (thanks) and am investigating further.
We would
probably go the Matrikon route, since Foxboro's OPC gateway software
apparently
isn't released yet.
So now I'm looking at how exactly I'm going to represent this data
in the I/A
system. I don't want to poke those values into another CP, as that
seems a
waste of nodebus bandwidth and processing power on that CP. I'd
like to use our
AW itself as a "virtual CP", if that's possible (this is not
critical data). I
suppose another option is getting a Modbus integrator and hooking it
to the OPC
PC, using OPC-to-Modbus-slave gateway software rather than
OPC-to-I/A gateway
software, but bandwidth could be limited by the serial link. Any
other options?
If anyone has done this, I'd greatly appreciate some war stories.
IIRC, someone
in Europe had a similar setup using the Matrikon software. If it's
long and
involved, feel free to reply off-list.
