Hello, Need some advise on the following: Need to build a timed operation circuit. The operator will determine the time from the panel view by hitting a up or down pb to determin the on time and another pb to determine the off time which will show up in a box above the operators and state how long the the operation will be on and off. What I need to know is how to implement this design into the plc logix. any help or examples would be very helpful thank you :-3
