Enumeration

Value | Definition | Pset
FLOATING | Output increases or decreases at a constant or accelerating rate | NO
PROPORTIONAL | Output is proportional to the control error | NO
PROPORTIONALINTEGRAL | Part of the output is proportional to the control error and part is proportional to the time integral of the control error | NO
PROPORTIONALINTEGRALDERIVATIVE | part of the output is proportional to the control error, part is proportional to the time integral of the control error and part is proportional to the time derivative of the control error | NO
TIMEDTWOPOSITION | Output changes state for a time interval proportional to the deviation from setpoint | NO
TWOPOSITION | Binary output, can be either on or off | NO
USERDEFINED |  |
NOTDEFINED |  |
