I misunderstood the question. In addition to Ron's options, you could load the AIM*OPC DA Server in the other guy's machine and use the Matrikon OPC Data Handler. This software lets two OPC Servers talk to each other. There are caveats though: 1) The movement of data from the other guy to I/A Series uses one-shot sets and they can be slow - 10 points per second. 2) There is extra configuration. You should probably store the remote data in a Shared Variable or Application Objects in the AW used by the OPC DA Server to get its data.
