A boolean tag, to trigger the alarm on the rising edge

Ignition
1

Hi,

I have configured a boolean tag, instead of using PLC, I want to use ignition alarm function to configure a alarm on the rising edge of the signal, means the alarm should be triggered when the signal is changing from 0 to 1.

I couldn't figure out the way to do it in the alarm configuration option.

Maybe I missed out some information, appreciated if anyone can advice.

Can't you just trigger alarm if it's equal 1 (true) :thinking:?
