I am setting up some alarms and one of them consists of making sure my sp and pv are within 10 degrees of each other and if they aren't for more than 10 minutes, the alarm activates. I did something like this awhile back but i am rusty.
I believe i divided the setpoint by the process variable and then put that into a limit function.
For a 25% difference either way, i would be looking at a limit value of 1.25 and .75.
Does that make any sense?
