Hi Team,

Please confirm the times set for PI ACE schedule is in seconds?

If Period is 60 means, how many minutes are there?

Ah, I just put together that you're talking about in reference to view you get in ACE Manager, yes the Period listed there should be in seconds

If you want to confirm this for yourself, you can select the context then go to Context (in the menu bar at the top) > Edit Schedule and Priority. This will open up the view I showed above.

and one more what is

**Calculation Limit**in PI ACE? As shown in pic period is 10 and Calculation limit is 600. Means what?Is it taking 600 for execution?

Hello Samit,

Have you considered to consult the manual?

PI ACE 2010 R2 User Guide says:

**Calculation Limit**: Sets/returns the maximum amount of time in seconds that a calculation can take.Not clear? My question is if period is set to 60 sec and calculation limit is set to 600 sec.

My module taking is executing on 600 sec. why?

Also please share the link for user manual?

Hello Samit,

The latest version of the manual (PDF format) is PI ACE User Guide for Visual Basic .NET (English). With PI ACE installed you can find a compiled help (PIACEUserGuideVB6.chm) version of the manual at %pihome%\ACE\Help

The Calculation Limit is not directly related to the schedule and I believe the default value is 600 because this works in the majority of cases. So Calculation Limit defines the time in seconds a calculation can take. I admit that I haven't tried this but expect that if the Calculation Limit becomes exceeded, PI ACE Scheduler will cancel execution and write 'Calc failed' to output points. With Calculation Limit set to 600 sec., the execution time is not becoming extended to 10 minutes but 10 minutes is the maximum period of time you allow your module to complete calculation.

Hi Samit,

Maybe I'm misunderstanding your question here, but you have the option in the drop-down when scheduling your module to use seconds, minutes, hours, etc. so it should be obvious from there

Cheers,

Rob
