Hello again. It is a very simple program to notify an operator when 2 filters need cleaning. Filter A needs cleaning after 1 hour of use and filter B needs cleaning after 2 hours of use. At the moment the program is workimng like this - If I1 and I2 are switched on, the counters start counting which is correct. Then, if I1 and I2 are switched off after 30mins and then switched back on again 15mins later and left on, the output of the hour counter is switched on 1 hour after I1 and I2 were first switched on. This is not correct as the filter would have only been in use for 45mins. A traditional mechanical hour counter only counts when a machine is running, if the machine stops then the counter stops. That is what I am trying to achieve. Thanks again for your time and help. AttachmentFilter Timer.zip (332 Downloads) |
