Does anyone know a way i can keep track of time? I have done many searches and found the RTC function but this is not what i need.
I need an hour meter which will keep track of ON time which one of my devices are on. Once i shut down the system, i will store this time in a retains.
I undertand all parts, except the time portion? Any help would be great!

Codesys bob,
Did you get any satisfaction on making a machine run hour meter?
I take it that you need to start and stop like a stopwatch and reset?
Started with time() FUNCTION?.

I have not had any luck. I even tried making time by using timers but my program is freewheeling so timers wont work as the cycle time is not always the same. I tried the oscat website seen below and cant seem to get it in english. Has anyone else run into this? I simply need to start keeping track of time once a signal i receive goes high.
Thanks in advance for all replies. I dont want to have to put an old school hour meter in when i have a $5K touch screen which i would think SHOULD be able to keep track of time!!

and timers are independant of the looptime. however not a good choice to use.
an easier way is to run a task every second and when motor running time is added 1 (and it should be remanent obvious.
when you change the software it will need to be on paper, as the location will be different.

two ways to do this:
use a timed POU in a task running every second or minute and add one to it in a retained variable
or have a look in w www.oscat.de w for a lot of functions that can be used in codesys

within oscat goto downloadmanager
then you need to accept it on the bottom
and you will get a list with lots of languages and possibilities.

look for ontime that is a simple secondmeter
see explanation the VAR should be persistent and retain.
in the text version you can have a look at how it is done in structerd text.
