Unity XL Pro Freeze Value
Unity XL Pro Freeze Value
(OP)
Hello,
I'm working in Unity XL Pro using functional block diagrams.
There is a "rate of change" value that is constantly being derived and thus changes frequently. I want to hold this value steady when an emergency button is actuated.
What I currently have is a move block. The enable pin on the move has the emergency button on a rising trigger feeding into it. Want it to be an instantaneous value the second the button is pushed. This is not working - when the rising trigger is activated the move does not move - is not enabled. Does anybody know why this would be the case?

What software are you using, danw2?

I do something similar with logic which freezes the last good value when an analog input fails, all you need is the OR and SEL instructions.
Delete the second OR, MOVE and R_TRIG.
Remove the Negate from the SEL G Pin.
Move the link connected to the SEL IN1 to IN0
Put a copy of the tag P_U1_CAM_NOZ_E_Flow_Cmd on IN1.
Now if the ESTOP is not tripped your passing the changing value to the tag.
If ESTOP comes on, you now pass the tag into itself effectively freezing it to its last good value.
