Hi, I added lots of logic(include I/O Cards) and tags into the existing contrologix PLC program. Can I just upload online controllogix's data into this offline program and keep the offline's added logic and tags' data no change. Otherwise, I have to upload the logic and data into another offline program and merge the added logic and tags to uploaded program and then download. It will take lots of time. Or, is there a way for offline download to keep the current online data (include setpoint etc) no change? Thanks a lot.
