Can you simulate your touch screen program with a ladder program using emulate. I am using rs500 and factory talk view studio with rs logix emulate500.
As a communication method from FactoryTalk Studio to the Emulation look for 'SLC500(DH485) Emulator driver'. It works from RSLogix500 to the emulator. It may also work for the FactoryTalk. I know a co-worker did this but I'm not sure how. I believe the Emulator documentation has details.
