The Pro-C controller will allow for only a single program to run at a time. Therefore you will have to be sure no two programs overlap.
In the Set Station Run Times position the Total Run Time calculator will help show what the total amount of time to finish a cycle is going to be for that particular program. The total run time calculator will show up after the last stations run time. After the total run times for each program are assessed the Start Times can then be staggered to guarantee there is not a program trying to come on when another program is still running.
Multiple programs can be run at the same time on the Hunter ACC controller and the Hunter I-Core controller.
