Hi! I would like to ask for help. I have 2pcs of vacuum pumps, I want to switch to operating hours, which one to go. Switching should only take place in a stationary position. I have written 2 hours of operation time counter. There are two outputs MB0: M101 engine start, MB1: M102 engine start. I have outputs for both operating hours. If set to <= current operating hours, MB2 and MB3 outputs are active (SET). How can I do my logic simply? V130 PLC Thanks!
