Can't find function block '' STOPWATCH'' on LOGO

Hello,

Can anyone advise please?

I have got LOGO 6ED 1052-1MD08-0BA0

I have made a project using DEMO Logo comfort software, which works nice.

Problem is I can't find function block '' STOPWATCH'' on my LOGO device !

It does have all the special functions like Shift register, Math error detect, PWM, Analog diff trigger, comparator , astron. clock, etc but I can't believe there is no simple STOPWATCH !

I need a function block which will display a time  DATE/HOURS-SECONDS  when a machine was turned on+ running time counter , and when the machine stops it needs to show how long it has been running for.

It all works well using STOPWATCH function when I simulate it on Comfort software,

Hello Ixo,

Thanks, for the quick reply.

I am not worried about the DEMO software now really, I just want to ''somehow'' achieve so the logo show on it's display for how long time the machine has been running from since it has been turned on in a normal format  hours:minutes:seconds

And if possible, if it the machine has been turned OFF, the time on display would stop. This is so we know how long has been the newly made machine by us running. 

I am still programming my LOGO manually anyway, because I only have demo licence.

See the attachement what I mean. Even if the date is not there its not a massive problem.

Minimum I want to have:

1. running stopwatch since the the machine has been turned ON

2. When stopping the machine, the time would stop and display would show the total running  time

Where is the problem to start the stopwatch ? Connect the output Qx to the EN input of the stopwatch. If you parameterise the stopwatch in ms, then you only can measure up to approx. 10 minutes, better is to use s for full seconds. Another option is a counter with a pulse generator 0.5s on and 0.5s off, then the maximum value will be greater.

If you have want, that the stopwatch or the counter should start at 0 every time, then use a AND EDGE block and connect it to reset of the stopwatch or counter.

Depend of milliseconds or seconds use the right setup in the message text to show e.g. hh:mm:ss.

If you also need date and time of start, then you need two messages, one message with the timestamp of the start and the second message with the on-time.

Scorp , the problem is I can't find stopwatch on my new logo 12/24 RCE

6ed1052 1md08 0ba0.. Its probably not there?

And if I use pulse counter as a second option, I can't do it so it show normal time, it shows  instead something like 1523 seconds, etc 

I need something like in normal time format   1:02:53

The main problem is the manual methode to edit a program. If you need a stopwatch, then create a new block and change inside the block to any analog flag, e.g. AM1. Then select the input and change to AF, then you can find the stopwatch. But don't ask me for alle keys and the right sequence i have used to test it.

This is the worst methode to create a program or changing something later. Think about to invest little money for the full version of Logosoft comfort.

Additional tip, also counter values can be displayed in hh:mm:ss format, see online help of message text in Logosoft demo.

Scorp, you are the star ! This is the info I needed, I have now found the stopwatch inside of the LOGO menu  

Thank you very much !
