Mounting and Commissioning
3.3 Commissioning
Structure of the Test Dialog Box
The dialog box is classified into three groups: BI for binary inputs, REL for output relays, and LED for light-
emitting diodes. On the left of each of these groups is an accordingly labeled button. By double-clicking a
button, information regarding the associated group can be shown or hidden.
In the column Status the present (physical) state of the hardware component is displayed. Indication is made
by symbols. The physical actual states of the binary inputs and outputs are indicated by an open or closed
switch symbol, the LEDs by a dark or illuminated LED symbol.
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.
