3.3 Processing Quality Attributes
•
OperatorBlocked using the values
The OperatorBlocked quality attribute indicates whether an object transferred via GOOSE message origi-
nates from a device that is in a
the object is no longer being received and assumes the
Blocked quality was previously identified on the receiver device, the object can be treated differently at
the receiving end (see chapter
At the receiving end, the object may be treated like a dropped signal.
•
Source using the values
The Source quality attribute indicates whether the object was updated in the sending device.
You can find more detailed information in chapter
Influencing Quality by the Operating Modes
In addition to the normal operation, the device also supports further operating modes that influence quality:
•
Test mode of the device
You can switch the entire device to test mode. In this case, all data objects generated in the device (state
values and measured values) receive the quality attribute Test =
The CFC charts are also in test mode and all output data receive the quality attribute Test =
•
Test mode for individual functions, stages, or function blocks
You can switch individual functions, stages, or function blocks into test mode. In this case, all data
objects generated by the function, stage, or function block (state values and measured values) receive
the quality attribute Test =
•
Functional logoff of the device
If you take the device out of operation and want to isolate it from the supply voltage, you can function-
ally log off the device ahead of time. Once you functionally log off the device, all data objects generated
in the device (state values and measured values) receive the quality attribute OperatorBlocked =
This also applies to the output from CFC charts.
If objects are transferred via a GOOSE message, the receiver devices can assess the quality. The receiver
device detects a functional logoff of the transmitting device. After shutting down the sending device, the
receiver device identifies that the sending device has been logged off operationally and did not fail. Now
the receiving objects can automatically be set to defined states (see chapter
Affected by the User for Received GOOSE
•
Switching off individual functions, stages, or function blocks
You can switch off individual functions, stages, or function blocks. In this case, all data objects generated
by the function, stage, or function block (state values and measured values) receive the quality attribute
Validity =
Influencing the Quality through Hardware Supervision
Supervision functions monitor the device hardware (see chapter
the supervision functions identify failures in the data acquisition of the device, all recorded data will receive
the quality attribute Validity =
Influencing the Quality through Voltage-Transformer Circuit Breakers
If tripping of the voltage-transformer circuit breaker is detected (see chapter
Breaker), all recorded data will receive the quality attribute Validity =
