Hello, I am using an M91-2-UA2 for a project. During an auto cycle, I wish to pause the operation with an input and during this operation I want a timer to stop running (hold it's current value) and when the input is released I want the timer to continue from that value. In other words, when the pause button is pressed, the cycle freezes until a resume is hit. Do you have any thoughts? Regards.
