How did you ensure that your Trigger is actually working? Your Trigger is from a Digital Input or you are using some HMI? |

Unfortunately this is not only a viewing error, because the program also works DIFFERENTLY in PLC than in simulation mode. I've analyzed how the program is working and found out why. I've made a screenshots and attached to this post as a zip archive. 01 - simulation mode - B063 block is counting (I see it also in one of the bottom windows with AM3) the TL time and the output = 0 02 - simulation mode - B063 block is counting (I see in AM3 window) the TH time and the output = 1 03 - online mode - B063 block is counting (I don's see it in the block, but I see it in AM3) the TL time and the output = 0 04 - online mode - B063 block is not counting, because the trigger is missing The trigger is missing while program was running in PLC becaue in block B071 there was a low signal during one (I guess) cycle just in the moment of transition from counting TL to TH by B063. In simulation mode B071 block is always on (even during transistion from TL to TH by B063), so this is the difference. A simple solution is to put an off-delay timer after B070 block and it should be OK. I don't want to check it anyway because made a totally diferent option, which is working, so I don't want to change it back.
