We are currently running 3 point temp control of a kiln and recently had a thermocouple failure which caused issues with our heat up cycle. In this instance operations says the thermocouple failed low which is normally not the case; normally its high. To eliminate both scenarios I would like to take the middle number of the 3 temperatures and always revert to that as my set point for control. If I fail low or high on a TC it would select the middle temp range to control a gas valve. I would like to do this in controllogix 5000.
