So I finely got everything ready to go with me analog thermocouple cards and no having an issue with actual temperature. Here is the problem at room temp. with no heaters on the temp display on my HMI reads 85f-87f degrees which is pretty accurate. However, when i turn my heaters on they reach about 150f on the HMI dispay. (By the way this is on a Extrusion Blow Molder from the 70's that i have converted to Micrologix.) At 150f the plastic in the barrell should barely be hot enough to flow much less burn, but it is burning to a crisp. My other blow molder (still equipped with switches and relays from the 70's) run about 250f until the plastic will run and about 400f until it will burn. My guess is i dont have the SCP set up correctly.
I will post the pic of my logic.
