Emulate 5/500 had "debug" files for this. You would basically have to write an entire shadow program to emulate your real world process. If your logic thinks it's commanding a motor to go, then it better think it sees feedback from the contactor, product going by photocells, data coming in from barcode readers, or your logic won't work like the real world. It's more than just having IO cards in your tree. To truly "emulate" a program is a lot more work. It is also good to test out an idea or an algorithm (if you don't have, or are away from, a test processor). I find Emulate good for testing HMI development, and capturing screenshots for documentation. SoftLogix lets you control real IO with the "processor" being your PC. It can't communicate with real PLCs, and it can't control real IO. Emulate is intentionally limited to prevent you from trying to use it for actual process control.
