Testing The System Interface - Siemens SIPROTEC 7SD610 Manual

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 com-
missioning. Do not under any circumstances check them by means of the testing mode during „real" operation
performing transmission and reception 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 folder 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 3-16).
Structure of the Dialog Box
In the column Indication, all message texts that were configured for the system interface 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 entering 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.
