This group object is enabled if Deactivated has not been selected for the valve output.
This group object indicates the current valve status.
•
Bit 0: Setpoint received/control value received
This bit indicates whether or not the valve has received a valid control value.
– 0: Setpoint/control value received
– 1: Setpoint/control value not received
This bit retains the value 0 during the entire run time if cyclical monitoring is not used (for the operating mode in controller
mode or for the control value in actuator mode), because no cycle time was defined during which a new value must be
received.
•
Bit 1: Output error
The bit indicates whether there is an error on the valve output. This may be a short circuit or overload.
– 0: No error
– 1: Error at output
•
Bit 2: Forced operation
Indicates whether forced operation is active or not.
– 0: Forced operation inactive
– 1: Forced operation active
•
Bit 3: Valve purge

The group object indicates the active valve control value from 0...100 %.
20
This group object is enabled if Deactivated has not been selected for the valve output.
If there is a fault on the output, e.g. due to short circuit or overload, the fault LED for the valve outputs flashes. At the same
time the group object sends a telegram with the value 1.
The output is switched off in the event of a fault.
The group object value is 0 after the fault has been rectified.
Indication by LED only on devices with manual operation.
