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 Ist column of the dialog box. To do this, the dialog box

must be updated. The options may be found below under the margin heading „Ak-

tualisieren der Anzeige“.

• 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 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 sec) if the Au-

tomatic Update (20sec) field is marked.

Exiting the Proce-

dure

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

ware components are set back to the operating state specified by the plant states. The

processor system is restarted, then the device is ready for operation.
