Using a DRO in a Brain

[rkowash]

I am trying to use a Y axis DRO to trigger clamps to release.  What I would like is to watch the DRO, and when it is between 10 and 20 inches from Z, to release an air cylinder (over ModIO).  I have control of the cylinder in a different brain.

I set up a brain that uses the Y axis DRO, then a >10, then a <20, then a NOP, then the modio address.  When I watch it and move the axis, the DRO value doesn't change.

Any thoughts?

Yea, simple solution.

an example brain is attached.

but

YDro>compare(>10)
                               >AND these two drocompares>Output(x)
YDro>compare(<20)

See attached Brain,

Thanks Scott, I figured out that I need to enable the brain if I actually want it to work.
