Config.InputUpperWarning REAL 3.402822e+38 Warning high limit of the process value
If you set InputUpperWarning outside the process
value limits, the configured absolute process value
high limit is used as the warning high limit.
If you configure InputUpperWarning within the process
value limits, this value is used as the warning high
limit.
InputUpperWarning > InputLowerWarning
InputUpperWarning ≤ InputUpperLimit
Config.InputLowerWarning REAL -
3.402822e+38
Warning low limit of the process value
If you set InputLowerWarning outside the process
value limits, the configured absolute process value low
limit is used as the warning low limit.
If you configure InputLowerWarning within the process
value limits, this value is used as the warning low limit.
InputLowerWarning < InputUpperWarning
InputLowerWarning ≥ InputLowerLimit
Config.OutputUpperLimit REAL 100.0 High limit of output value
For details, see OutputLowerLimit
OutputUpperLimit > OutputLowerLimit
Config.OutputLowerLimit REAL 0.0 Low limit of output value
For Output and Output_PER, the range of values from
-100.0 to +100.0, including zero, is valid. At -100.0,
Output_PER = -27648; at +100.0, Output_PER =
27648.
For Output_PWM, the value range 0.0 to +100.0 ap-
plies.
The output value limits must match the control logic.
OutputLowerLimit < OutputUpperLimit
Config.SetpointUpperLimit REAL 3.402822e+38 High limit of setpoint
If you configure SetpointUpperLimit outside the pro-
cess value limits, the configured process value abso-
lute high limit is used as the setpoint high limit.
If you configure SetpointUpperLimit within the process
value limits, this value is used as the setpoint high
Config.SetpointLowerLimit REAL -
3.402822e+38
Low limit of the setpoint
If you set SetpointLowerLimit outside the process
value limits, the configured process value absolute low
limit is used as the setpoint low limit.
If you set SetpointLowerLimit within the process value
limits, this value is used as the setpoint low limit.
Config.MinimumOnTime REAL 0.0
The minimum ON time of the pulse width modulation in
seconds is rounded to
MinimumOnTime = n×CycleTime.Value
Config.MinimumOffTime REAL 0.0 The minimum OFF time of the pulse width modulation
in seconds is rounded to
MinimumOffTime = n×CycleTime.Value
