Proceed as follows in order to check the binary inputs:
• Each state in the system which causes a binary input to pick up must be generated.
• Check the reaction in the Status column of the dialog box. To do this, the dialog box
• Finish the test sequence (see margin heading below „Exiting the Procedure").
If, however, the effect of a binary input must be checked without carrying out any
switching in the system, it is possible to trigger individual binary inputs with the hard-
ware test function. As soon as the first state change of any binary input is triggered
and the password No. 6 has been entered, all binary inputs are separated from the
system and can only be activated via the hardware test function.
Test of the LEDs
The light-emitting diodes (LEDs) may be tested in a similar manner to the other in-
put/output components. As soon as the first state change of any LED has been trig-
gered, all LEDs are separated from the internal device functionality and can only be
controlled via the hardware test function. This means e.g. that no LED is illuminated
anymore by a protective function or by pressing the LED reset button.

When the dialog box Hardware Test is opened, the present conditions of the hard-

To end the hardware test, click on Close. The dialog box closes. Thus, all the hard-

Checking the Protection Data Topology

General
The communication topology can either be checked from the PC using DIGSI or with
a „ WEB-Monitor". If you choose to work with the „WEB-Monitor", please note the Help
files referring to the „WEB-Monitor".
You can either connect the PC to the device locally using the operator interface at the
front, or the service interface at the back of the PC (Figure 3-18). Or you can log into
the device using a modem via the service interface (example in Figure 3-19).
