After finishing the hardware test, the device will make an initial startup. 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
symbolically. 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.
