284 Process Control Instruction
Setpoint (SPS)
The SPS (Setpoint) is the desired control point of the process variable.
Process Variable (PV)
The PV (Process Variable) is the analog input variable.
Setpoint MAX (MAXS)
If the SPV is read in engineering units, then the MAXS (Setpoint
Maximum) parameter corresponds to the value of the setpoint in
engineering units when the control input is at its maximum value.
