This type defines control which is used for multi state discrete output.
Setpoint: ABP645#001 defines in a control loop, the multi-state target value the process value is intended to assume.
OperatingDirection: ABD740#002 defines output change to a given input signal, for example direct or reverse.
FaultState: ABP651#001 defines replacement value of a multi-state output in the case of a failure.
ABP644#001 defines parameter indicating the discrete readback value in a control loopThe components of MultiStateDiscreteControlVariableType have additional references which are defined in Table 203.
