Calculation for signals of different times

[Gutenberg]

Hi,

I'm using Signal Express 2013, and have a difficulty in the software.

I use 2 different analog sensors as an Input. I would like to subtract a value of one sensor in the value of the this same sensor of different timestamp depending on the value of the other sensor.

That means, if sensor B reaches the value of '1' - then show me the result of: value of sensor A now subtracted in the value of sensor A in the previous event that it happened.

Is it possible at all to access values of older timestamps during measurement?

Thanks,

Reut

I think that you could log the measurements and then make that process with the data? 

something like this:
