Whats the best way to display on the front of the logo how long the machine has been running for on the day and then start it again the next to monitor down time of the machine 

Thanks

Hi.

When reading the post, I think to myself -
"Myself", here is a guy who want us to do his work for him!

Andrew, then I see your name and I know you are not THAT GUY.

I suggest you create a sample program and show us (me) where you get stuck.
This is the maximum way to learn from this.
Then let us take it from there - okay?

Just maybe you are under time restraints.
So you are welcome to disagree and ignore my suggestion.

ixo65 - what do you think?

Yuo make a counter by your self

Take a a-synchronos puls generator, thats makes pulses every second

You count the seconds if the motor is ON, Count in an other counter the seconds when the motor is OFF

Taka a mathematical function and divide the seconds by 3600 and you get the hours.

You can reset them when you wishes, this is the most flexiblele way to get an hour counter

Hi

Thanks for the reply. 

As for other post on the forum they are for my benefit only as i have bought the equipment to try and better myself on the logo/siemens gear so in effect self learning myself. So am thankful for the members of the form for the help given.

back on topic.

i will get a sample together and post it here

Hello Andrew,

I think there is a function just for your case: Hours Counter.

By this function you can define:

OT - Operating time - time which the machine runs.

MI - Maintenance interval - time for the next maintenance.

MN - Time remaining to the next maintenance.   MN = OT - MI (all in hh:mm)

The times can be showed on the display. The times can be reseted partial or totally.

I didn't undestand your entire statement but if you want also define some days of a week to the maintenance, you have to change the input I1 for a Wekly timer swtching EN from Hours Counter.

See attached a draft for this.

Hi

thanks for the example i have tried this in the simulator and i can see how the output becomes on 

Thanks
