Hello,
I'm currently trying to design a process with ignition and would like some feedback on it. I am using Ignition 8.1.30 and I am making this in perspective using only a database.
My goal is to use a table that has a named query attached to it and grab the last two time stamps or rows and compare them to see if there was gap in between the minutes.
Example
Temp TimeStamp
42 C 2:31 pm
55C 2:33 pm
2:32 pm is missing, so I would like to continuously check the last two rows every minute and create an alarm system that stores the time it happened.
I was thinking of using Gateway Events. Is it possible to access the table values from Gateway Events?
Is there a better solution for my needs?
Thank You
