How to get process time of an instance from its tree ?

sebastien_b49 — Tue, 05 Mar 2019 11:56:00 GMT

Hello !

I would like to store the total processing time of each instance of my machines.

I used to do it with a statistics collector but all the state times are already registered in each instance's tree under the path: "instance/stats/state_current/profile".

Is it possible to access the processíng time stored in the instance's tree from the model, for instance from the instance's Exit trigger ?

Best regards,

You can use this code

executefsnode(getvarnode(Model.find("Processor1"), "cycletime"),0);

The node for processing time is a script node, so this executes the script in that node and returns the processing time, but only if the processing time was a set number, not based off the item's type or such. If the processing time is constantly changing, then in the code for the processing time, tell it to change a label on the processor and read that label on the instances exit trigger.

@Joshua S

I actually meant the processing time in the stats node.

Can it also be retrieved ?

Object processor = Model.find("Processor1");
return processor.stats.state().getTotalTimeAt("processing");

From the On Exit trigger:

current.stats.state().getTotalTimeAt("processing")

Great ! Thank you phil ! I did not know of the method.

You said "If the processing time is constantly changing, then in the code for the processing time, tell it to change a label on the processor"

How would I do that?

Thanks!

This picture illustrates what I was referencing. In this case an item coming in already has a label on it that is changing the Process time, but in the code for the Process Time, you can add a line, in this case

current.ProcessTime=item.ProcessTime;

@Joshua S

Thanks for the quick answer!

What if I have a situation of 'process time by case' where for every case I have a statistical distribution?
What I want is to get the process time value generated by the distribution so I can use it to change a keyframe variable for the animation of the processor.

In the end what I'm trying to accomplish is to make a progress bar that works for any time generated by the process time distribution...

If I use 'getvarstr(current, "cycletime")' it gives me the actual code that generates the value I want... Since I'm not a coder I don't know how to get it lol

The item itself stores its processing time. You don't need to store it manually on a label as Joshua suggested. You can get it with the command getitemvar(item, 2).

You can use the following code snippet to calculate a percentage of how complete a flowitem's processing time is:

treenode item = Model.find("Processor1").first;

double startTime = getitemvar(item, 1);
double totalProcessingTime = getitemvar(item, 2);
return (time() - startTime) / totalProcessingTime;

Hi @phil.bobo,

I tried using this code also for getting the "scheduled down" time of a Sink, but it does not work, although the arborescence in the tree is the same. Is there any reason ?
