[TRNSYS-users] signal-depending summing unit?

[Jochen Doell <jochen.doell@ise.fraunhofer.de>]

Hello,

I have a maybe quite simple problem.
I want to investigate the operating behaviour of an absorption chiller.
In my deck i have a controller which gives me 0 or 1 as a function which 
controls this chiller. Now i want to know the mean-operating-period, 
that means if the machine starts running, how many timesteps does it 
continue until it stops (on the average).
What i need is something like a "signal-depending summing unit". Ideas?

Thanks in advance,
Jochen
