studio 5000 ultilzation chalenge

Hello ,

I have an interesting programming chalenge and i was wondering if anyone has ever had a similar request?

I have been asked to monitor and record how often a machine is running and express this as an overall machine ultilization, The logic for the machine run verses machine down is pretty strait forward the problem is that some portion of the machine downtime is with the power off and no power to the proccesser.  ThIs would all be done in Studio 5000.

Thanks
