DSP PI Controller

Hello Ben,

I am having issue to get going with the new DSP PI and PID component (used it many times in V7 and V8) :oops:
I have two digital values Setspeed and Actual Speed which is my Set and Feed back signals ( as they come over CAN they are numerical values in RPM)
I connect these two values to the PI Component by a Digital Input icon as below however my issue is how to extract the output from the PI component
I use the Process(macro) but I do not see any way to get the value, I also try to use a Digital output but I cannot connect the Digital output to the PI Components.

What am I doing wrong or do not understand Please help as always it isappreciated

Aha excellent thanks for that they all work here but I delayed pushing them out to the update system to confirm everything was ok and now they are no longer flagged as needing pushing.

I'll get these pushed out for you now.
