Test of the Binary Inputs
To test the wiring between the plant and the binary inputs of the 7UM62, the condition in the system which ini-
tiates the binary input must be generated and the response of 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:
• Activate in the system each of the functions which cause the binary inputs.
• The response of the device must be checked in the Status column of the dialog box. To do this, the dialog
box must be updated. The options may be found below under the margin heading „Updating the Display“.
• Terminate the test sequence (see below under the margin heading „Exiting the Procedure“).
If however the effect of a binary input must be checked without carrying out any switching in the plant, it is pos-
sible 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 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 you have initi-
ated the first state change for any LED, all
LEDs are disconnected from the functionality of the device and can
only be operated by the hardware test function. This means e.g. that no LED is illuminated anymore by a device
function or by pressing the LED reset button.
Updating the Display
During the opening of the dialog box Hardware Test the operating states of the hardware components which
are current at this time are read in and displayed.
An update occurs:
• for each hardware component, if a command to change the condition is successfully performed,
• 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
(20sec) field is marked.
Exiting the Test Mode
To end the hardware test, click on Close. The dialog box closes. The device becomes unavailable for a brief
start-up period immediately after this. Then all hardware components are returned to the operating conditions
determined by the plant settings.
