Automatic Control Module Channel Data (NO) trigger

[ptrenta]

Hello,
i need to set value giving command on a group of device OPC UA, when push button:

Button ON – send value 1 to command 1 to device (211,212,213 )
Button OFF – send value 0 to the same group

i have channel 30010 connected to button OFF and channel 30011 connected to button ON
OUTPUT CHANNEL
30010 -> SetVal(20011,0)
30011 -> SetVal(20011,1)
in this way the buttons change value of input 20011 (Calculated Discrete)

With Automatic Control Module i can trigger the input and send the commands to devices.

The problem is that if i push 2 times button ON, the 2th time the action is not executed, seem that “channel data trigger” trigger only when the value change.

Is there something wrong?

Hello,
Triggers of the “On channel data” type fire when channel value changes. In your case, may be an “on command” trigger would be more appropriate.

You’re right, in effect i had to solve with a not elegant working solution.
“on command” works very good.

Thanks
