Hi. I am very very new to plc. Whatever i know is through google and youtube only (so very limited knowledge). I need help about how to use plc clock or real time in a plc. I am using cpm2a with cx-programmer. I need to unlatch a door at a certain time everyday. The door needs to b unlatched for 30 min at a specific time 5 days a week (mon to fri). Is it possible?
