Config.VirtualActuatorLimit REAL 150.0 If all the following conditions have been satisfied, the actua-
tor is moved in one direction for the maximum period of
VirtualActuatorLimit × Retain.TransitTime/100 and the warn-
ing 2000h is output:
• Config.OutputPerOn = FALSE
• Config.ActuatorEndStopOn = FALSE
• Config.FeedbackOn = FALSE
If Config.OutputPerOn = FALSE and Con-
fig.ActuatorEndStopOn = TRUE or Config.FeedbackOn =
TRUE, only the warning 2000h is output.
If Config.OutputPerOn = TRUE, VirtualActuatorLimit is not
taken into consideration.
As of PID_3Step Version 2.3 the monitoring and limiting of
the travel time can be deactivated with Con-
fig.VirtualActuatorLimit = 0.0.
Config.InputScaling.Upper-
PointIn
REAL 27648.0 Scaling Input_PER high
Input_PER is converted to a percentage based on the two
value pairs UpperPointOut, UpperPointIn and Lower-
PointOut, LowerPointIn of the InputScaling structure.
Config.InputScaling.Lower-
PointIn
REAL 0.0 Scaling Input_PER low
Input_PER is converted to a percentage based on the two
value pairs UpperPointOut, UpperPointIn and Lower-
PointOut, LowerPointIn of the InputScaling structure.
Config.InputScaling.Upper-
PointOut
REAL 100.0 Scaled high process value
Input_PER is converted to a percentage based on the two
value pairs UpperPointOut, UpperPointIn and Lower-
PointOut, LowerPointIn of the InputScaling structure.
Config.InputScaling.Lower-
PointOut
REAL 0.0 Scaled low process value
Input_PER is converted to a percentage based on the two
value pairs UpperPointOut, UpperPointIn and Lower-
PointOut, LowerPointIn of the InputScaling structure.
Config.FeedbackScaling
.UpperPointIn
REAL 27648.0 Scaling Feedback_PER high
Feedback_PER is converted to a percentage based on the
two value pairs UpperPointOut, UpperPointIn and Lower-
PointOut, LowerPointIn of the FeedbackScaling structure.
Config.FeedbackScaling
.LowerPointIn
REAL 0.0 Scaling Feedback_PER low
Feedback_PER is converted to a percentage based on the
two value pairs UpperPointOut, UpperPointIn and Lower-
PointOut, LowerPointIn of the FeedbackScaling structure.
Config.FeedbackScaling
.UpperPointOut
REAL 100.0 High endstop
Feedback_PER is converted to a percentage based on the
two value pairs UpperPointOut, UpperPointIn and Lower-
PointOut, LowerPointIn of the FeedbackScaling structure.
Config.FeedbackScaling
.LowerPointOut
REAL 0.0 Low endstop
Feedback_PER is converted to a percentage based on the
two value pairs UpperPointOut, UpperPointIn and Lower-
PointOut, LowerPointIn of the FeedbackScaling structure.
