Ok, to start I am a beginner and any response will be greatly appreciated. I am installing a Panelmate 1700 plus on a Modicon 984-680 PLC. My questions are pretty basic. How does the interface change and edit registers? Does the old thumbwheel T->R logic still need to be in the plc logic? Basically, how does the panelmate change the inputs that would normally be from a thumbwheel? Any other knowledge by someone who has performed this seemingly impossible task is appreciated.
