Good day All. I am trying to have an alarm go off when the the tag value is "Uncertain_InitialValue". In the alarm setup - alarm mode settings - mode I dont not see "Uncertain_InitialValue" I do see bad but im not getting bad data im getting uncertain data due to the machine being turned off. Its just what the customer wants.
How can I go about having this alarm setup to trigger in this state?
Here is a good thread to read which recommends not to do this and why.
Long story short just checked if its good or bad.
It sounds like you want to know if the device is on or off. In that case I'd recommend a heartbeat in the device. And checking in Ignition if stays stagnant for x amount of time the device is obviously off.
