I have an program on one computer (Windows 7 using DSC and NI OPC Server) that works with an Allen Bradley plc. I want to build an executable of a copy of this program to run on an Allen Bradley touch panel (running Windows XP) that will access the shared variables of the original program. The two computers are on the same network. My first attempt failed as I simply used the same shared variable library in my build and the other computer threw and error about OPC server not being licensed. I called NI and the rep suggested that I can do this if I can get the copied program to link/load a different library with shared variables of the same name but the address altered to link to the original program. But he couldn't tell me how to do this. Any ideas?
