3.3.3 Checking the Binary Inputs and 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!
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 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 screen.
• Double-click in the list view on Hardware Test. The dialog box of the same name opens (see the following
figure).
Structure of the Test Dialogue Box
The dialog box is divided into three groups: BI for binary inputs, REL for output relays, and LED for light-emit-
ting diodes. On the left of each group is an accordingly labelled button. By double-clicking these buttons you
can show or hide the individual information of the selected group.
In the column Status the current status of the particular hardware component is displayed. It is displayed sym-
bolically. The actual states of the binary inputs and outputs are displayed by the symbol of opened and closed
switch contacts, those of the LEDs by a symbol of a lit or extinguished LED.
The opposite state of each element is displayed in the column Scheduled. The display is made in plain text.
The right-most column indicates the commands or messages that are configured (masked) to the hardware
components.
