Thanks Joe,
So if I understand correctly a 12ma signal will be converted to a value of 9830 which would equate to 5,000PSI which would be the result(F) value.
What I am trying to achieve is to turn a motor off when a certain PSI is reached. 4250PSI in this case.
Looking at other videos it looks like I need to use the store function and store the result value(F) into a Global Int16 Tag. I can then use this value and a compare function to enable/disable a bit and in turn, control my motor.
