Hi, i have the following situation, i have a blower which has some of the following tags in s7 400
Time since last reset
Machine rotation time since last reset.
Good Bottles since last reset.
bad bottles since last reset.
and more but same situation.
currently we are resetting the information from the HMi from the blower. which keeps a record of the period and the information, and resets the counters to 0.
right now we use it per run, so we run a orange soda when we finished the operator finished the run and a new run starts.
what i would like to do is the following.
keep record of not only the run, but by shift, day or anyway i would like to do it.
so i have the tags created in ignition and can see the values. i don’t really know how to separte this values since last reset to a shift or day values. since the problem is that when it restarts a run it would clear everything.
ideally it would be to have a
Shift start time
shift Machine rotation time
shift Good Bottles.
shift bad bottles
and so on.
so im not really sure how to create a tag or tags to keep this memory. anybody help would be aprpeciated im really stuck in this and need this to calculate. production efficiency per shift, per day, or per date range. so far the way i have it i can only calculate per reset.
when they press the push button i recoed the values in a transaction group, if succes, i then set the value in the plc to actually reset the counters to 0. but this is only per run. and i can have a run that can go more than 1 shift. and sometimes i have many runs in one shift.
