Proceed as follows in order to check the binary inputs:
• Activate in the system each of the functions which cause the binary inputs.
• Check the reaction in the Status column of the dialog box. To do this, the dialogue
box must be updated. The options may be found below under the margin heading
“Updating the Display”.
• Finish the testing (see margin heading below “Exiting the Procedure”).
If you want to check for the effects a binary input can have, you can do so by control-
ling individual binary inputs with the hardware test. 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 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 is illuminated anymore by a protection function
or by pressing the LED reset button.
Updating the
Display
When the dialog box Hardware Test is opened, the present conditions of the hard-
ware components at that moment are read in and displayed.
An update is made:
• for the particular hardware component, if a command for change to another state
was successful.
• for all hardware components if the Update button is clicked,
• for all hardware components with cyclical updating (cycle time is 20 seconds) if the
Automatic Update (20 sec) field is marked.
Exiting the Proce-
dure
To finish the hardware test, click on Close. The dialog box closes. The hardware com-
ponents are again reset to the original operating state determined by the plant condi-
tions. The device is not ready for operation for a short time during the following startup.
3.3.5 Checking the Communication Topology
General The communication topology can either be checked from the PC using DIGSI
®
.
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 3-20). Or you can log into
the device using a modem via the service interface (example in Figure 3-21).
