I'm using vijeo designer v4.7 to make graphics on my magelis hmi's. I'm trying to link the variables between twidosuite ND vijeo designer. I can open the file folder and see the variables but they won't link. If I start out with a new project in twidosuite and then go straight to vijeo designer the variables link perfect but if I come back to the twidosuite project and make a few changes , save and go back to vijeo designer and update the new variables it says it can't. Does anyone have any idea what's wrong. Thanks John.
