Test of the Binary Inputs
To test the wiring between the plant and the binary inputs of the 7SC805 the condition in the plant which initiates
the binary input must be generated and the response of the device checked.
To do so, the dialog box
Hardware Test
must be opened again 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 each of function in the system which causes a binary input to pick up.
• Check the reaction in the
Status
column of the dialog box. To do so, the dialog 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 Test Mode“).
If, however, the effect of a binary input must be checked without carrying out any switching 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 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 (if HMI is available)
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
message or by pressing the LED reset button.
Updating the Display
As the
Hardware Test
dialog opens, the operating states of the hardware components which are current at this
time are read in and displayed.
An update is made:
• 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 is closed. 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.
