3.3.3 Testing the System Interface
Prefacing Remarks If the device features a system interface and uses it to communicate with the control
centre, the DIGSI device operation can be used to test if messages are transmitted
correctly. This test option should however definitely „not“ be used while the device is
in service on a live system.
DANGER!
The sending or receiving of indications via the system interface by means of the
test function is a real information exchange between the SIPROTEC 4 device
and the control centre. Connected operating equipment such as circuit breakers
or disconnectors can be switched in this way!
Non-observance of the following measure will result in death, severe personal injury
or substantial property damage.
Equipment used to allow switching such as circuit breakers or disconnectors is to be
checked only during commissioning. Do not under any circumstances check them by
means of the testing mode during „real“ operation performing transmission and re-
ception of messages via the system interface.
Note
After termination of the hardware test, the device will reboot. Thereby, all annunciation
buffers are erased. If required, these buffers should be extracted with DIGSI prior to
the test.
The interface test is carried out using DIGSI in the Online operating mode:
• Open the Online directory by double-clicking; the operating functions for the device
appear.
• Click on Test; the function selection appears in the right half of the window.
• Double-click on Testing Messages for System Interface shown in the list view.
The dialog box Generate Indications is opened (see Figure 3-23).
Structure of the
Dialog Box
In the column Indication, all message texts that were configured for the system inter-
face in the matrix will then appear. In the column Setpoint you determine a value for
the indications that shall be tested. Depending on the type of message different enter-
ing fields are available (e.g. message ON / message OFF). By clicking on one of the
buttons you can select the desired value from the pull-down menu.
