To end the System Interface Test, click on Close. The dialog box closes. The processor system is restarted,
then the device is ready for operation.
Test in Command Direction
Data which are normally linked via binary inputs (first character „>“) are likewise checked with this procedure.
The information transmitted in command direction must be indicated by the central station. Check whether the
reaction is correct.
3.3.4 Checking the switching states of the binary Inputs/Outputs
Prefacing Remarks
The binary inputs, outputs, and LEDs of a SIPROTEC 4 device can be individually and precisely controlled in
DIGSI. This feature is used to verify control wiring from the device to plant equipment (operational checks)
during commissioning. This test option should however definitely „not“ be used while the device is in service
on a live system.
DANGER!
A changing of switching states by means of the test function causes a real change of the operating
state at the SIPROTEC 4 device. Connected operating equipment such as circuit breakers or
disconnectors will 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 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 hardware test can be 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 in the list view on Device inputs and outputs. The dialog box with this name is opened
(see Figure 3-30).
