Cursor formulas

Hi ,

Some of the DAQ software I've used has the option of generating formulas based on cursor info. For example calculating the slope of a speed curve by placing the two cursors on the speedgraph. Does Dewesoft have a capability to generate cursor formulas?

Thanks

Hi,

in the current version of DEWESoft you are unable to use the cursor info in math formulas. But you can access simple cursor math channels like distance between cursors, difference and change rate (difference/distance) to display them on a digital meter. To access these channels you must be in design mode and then you right click on a recorder and select the Info channels option. When you click this this window will appear:

Here you can select the values you want to see, but you cant use the channels you select here in a math formula (they can only be used in visual controls).

This feature is only avaliable in DEWESoft X2 SP7 and above. I hope these values can help you with your measurements.

Thanks for the quick reply,

I've enabled the info I want to see under the channel info window in Design mode. But where when I switch back to review window I don't see these channel info. Where can I see these values ?

Never mind, I had to restart the software to start seeing the values. They show up as new channels under the Tree view.

it seems there is the possibility to get the data from the yellow cursor with the .DATA(INDEX) function

you can add one function for each point you want to calculate, but they will be on a position relative to the yellow cursor itself (e.g. 'force'.DATA(0) will give the value of the signal 'force' at the cursor position, 'force'.DATA(200) will give the value of the signal 'force' 200 samples after the cursor position)

for simple functions like slope calculation it works, but of course this trick does not replace completely the formulas based on cursors positions
