tempo0512 Posts: 6 Rating: (0)	Good Morning, I'm a new user of logo 0BA6 The programm is now working well and I just get one difficulty : I try to send on the logo screen the information of the activation time of an analog threshold trigger. It mesures a pressure. I want to know how long I need to come from 1,5 Bar to 9 Bar and see it on the screen.It's Ok with the threshold trigger whitch switch from 0 to 1 at the right time, but how to get the information : "how many millseconds is the oultet at 1 ?" I'm looking at a solution since yesterday evening without any results. May you help me? Merci d'avance et bonne journée de France.

If the output of the treshold will be on for less than 99sec, the time will be displayed as long as the output will be on.

Of course you can start and stop a timer (e.g. on-delay) depending on a threshold, but if it is stopped, the elapsed time is set to zero. So you could always see only the running time. I think what you need is a selfmade stop watch. Some time ago, there was a solution in the german forum (thanks to Betel ). Please see the attachment. You only have to modify the min/max parameters in the a. threshold triggers B016 and B018. And you have to think about when the time shall be reset (I3). Maybe when the pressure is <1.5 bar? To be able use the stop watch without analog value i kept I1 and I2. Attachment Stop watch in ms.zip (247 Downloads)

But i think it is always good to write a short post, in which you tell the others that your problem is solved and maybe how you solved it. Best regards O_Moderator
