The problem I am running into is this, I have to be very careful with the PLC memory usage as I am working with a very large existing program. I need to create 3 sections of 6 buttons each, in which if one is on the others are off. I also would like these buttons only visible when certain conditions are met. I decided to use Radio buttons and mask out what I didn't want visible, which was a bust. So as much as I can I need to keep from writing extra RLL code to accomplish this. With In-touch I could write scripts to easily do all this, but it seems C-more is very limited in this area. Any ideas or help would be fantastic.
