Parameter and type
Data type
Description
ManualEnable
IN
Bool
Enables or disables the manual operation mode. (Default value:
FALSE):
•
•
A FALSE to TRUE edge activates "manual mode", while State = 4,
Mode remains unchanged.
As long as ManualEnable = TRUE, you cannot change the
As long as ManualEnable = TRUE, you cannot change the
operating mode using a rising edge at ModeActivate or use the
commissioning dialog.
•
A TRUE to FALSE edge activates the operating mode that is
assigned by Mode.
Note: We recommend that you change the operating mode using
ModeActivate only.
ManualValue
IN
Real
Output value for manual operation. (Default value: 0.0)
You can use values from Config.OutputLowerLimit to
You can use values from Config.OutputLowerLimit to
Config.OutputUpperLimit.
ErrorAck
IN
Bool
Resets the ErrorBits and warning outputs. FALSE to TRUE edge
Reset
IN
Bool
Restarts the controller. (Default value: FALSE):
•
•
FALSE to TRUE edge:
– Switches to "inactive" mode
– Resets the ErrorBits and warning outputs
– Clears Integral action
– Maintains PID parameters
– Switches to "inactive" mode
– Resets the ErrorBits and warning outputs
– Clears Integral action
– Maintains PID parameters
•
As long as Reset = TRUE, PID_Compact remains in "Inactive"
mode (State = 0).
•
TRUE to FALSE edge:
– PID_Compact switches to the operating mode that is saved in
– PID_Compact switches to the operating mode that is saved in
the Mode parameter.
ModeActivate
IN
Bool
The PID_Compact switches to the operating mode that is saved in the
Mode parameter. FALSE to TRUE edge:
Mode
IN
Int
The desired PID mode; Activated on the leading edge of the Mode
Activate input.
ScaledInput
OUT
Real
Scaled process value. (Default value: 0.0)
Output
1
OUT
Real
Output value in REAL format. (Default value: 0.0)
Output_PER
1
OUT
Word
Analog output value. (Default value: W#16#0)
Output_PWM
1
OUT
Bool
Output value for pulse width modulation. (Default value: FALSE)
On and Off times form the output value.
On and Off times form the output value.
SetpointLimit_H
OUT
Bool
Setpoint high limit. (Default value: FALSE)
If SetpointLimit_H = TRUE, the absolute setpoint upper limit is reached
If SetpointLimit_H = TRUE, the absolute setpoint upper limit is reached
(Setpoint ≥ Config.SetpointUpperLimit).
The setpoint is limited to Config.SetpointUpperLimit.
The setpoint is limited to Config.SetpointUpperLimit.
SetpointLimit_L
OUT
Bool
Setpoint low limit. (Default value: FALSE)
If SetpointLimit_L = TRUE, the absolute setpoint lower limit is reached
If SetpointLimit_L = TRUE, the absolute setpoint lower limit is reached
(Setpoint ≤ Config.SetpointLowerLimit).
The setpoint is limited to Config.SetpointLowerLimit.
The setpoint is limited to Config.SetpointLowerLimit.
InputWarning_H
OUT
Bool
If InputWarning_H = TRUE, the process value has reached or
exceeded the warning high limit. (Default value: FALSE)
