Re : 2 breakpoints' buffers based on 1 axis

[SamiBenF]

Hi,

I am really interested in the buffered breakpoint feature of the 735x boards.

However, I would like to configure 2 different pulse ouputs using buffered breakpoints but both based on the same axis. Would you think it is possible to do that ?

Indeed, I plan to trigger 2 cameras that are looking at the same conveyor but located at different places.

Thanks,

Sami.

Hi Sami!
How are you ?
Sorry for the delay, I didn't managed to find a 735x device yet to investigate tests and has you know you can't use this fonctionnality with a 734x device. There is something that I don't understand. Do you need only one 1D breakpoint position table for both camera based on only one axis? or do you need one separate 1D buffered position table for each camera?
If you need only one 1D table but 2 outputs, you can route the signal on two different RTSI lines?

Hi Manuel,

I'm fine thanks.
I will need 2 separate 1D breakpoints based on the same axis.
However, as the cameras are separated by a constant distance you can think about the breakpoint as bkpt2 = bkpt1 + (cam2 position - cam1 position).
That's why a workaround would be to output 1 breakpoint for cam1 and use it as a trigger to output a second delayed pulse from a 660x counter or from a 8254R pulse generator.

A+

Sami.
