the device checked.
To do this, the dialog box Hardware Test must again be opened to view the physical
state of the binary inputs. The password is not yet required.
Proceed as follows in order to check the binary inputs:
• Each state in the plant which causes a binary input to pick up must be generated.
• The response of the device must be checked in the Status column of the dialog box.
• Terminate the test sequence (see below under the margin heading "Exiting the Pro-
If however the effect of a binary input must be checked without carrying out any switch-
ing in the plant, it is possible to trigger individual binary inputs with the hardware test
function. As soon as the first state change of any binary input is triggered and the pass-
word no. 6 has been entered, all binary inputs are separated from the plant and can
only be activated via the hardware test function.
Test of the LEDs
The LEDs may be tested in a similar manner to the other input/output components. As
soon as the first state change of any LED has been triggered, 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 can be switched on anymore by e.g. a protec-
tion function or operation of the LED reset key.
