3.3.3 Testing the System Interface (at Port B)
Prefacing Remarks
If the device features a system interface and this is used to communicate with the control center, 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„real“ operation.
DANGER!
Danger evolving from operating the equipment (e.g. circuit breakers, disconnectors) by means of the
test function
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 com-
missioning. Do not under any circumstances check them by means of the test function during real operation by
transmitting or receiving messages via the system interface.
Note
After termination of the system interface 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 screen.
• Double-click Generate Indications in the list view. The Generate Indications dialog box opens (see follow-
ing figure).
Structure of the Test Dialog Box
In the column Indication the display texts of all indications are displayed which were allocated to the system
interface in the matrix. In the column SETPOINT Status the user has to define the value for the messages to
be tested. Depending on annunciation type, several input fields are offered (e.g. message „ON“ / message
„OFF“). By clicking on one of the fields you can select the desired value from the pull-down menu.
