I'd like trigger a 24v warning light to switch on after X number of cycles ( in our program a door switch activates 1 cycle) so my thinking is that I can either count the number of times the door is opened or log the run time of an extractor motor that starts when the door is opened. we have a "reset" button already installed and so I would like to use this to switch the light back off. Any advice on how I would do this is greatly appreciated. Best regards

What i would like to do is add in Q4 ( warning light) as we have a spare output on the plc currently, and when Q1 has been running for say 200 hours then Q4 gets activated and only goes out when our booth is reset I.E switched off and on again, is this possible? Best regards

So I only programmed the option of reaching 200 hours and setting a memory (B021) when it was reached and thus switching on output Q4. You have to program the reset of B021 yourself.
