Test in Message Di-
rection
For all information that is transmitted to the central station test in Status Scheduled
the desired options in the list which appears:
• Make sure that each checking process is carried out carefully without causing any
danger (see above and refer to DANGER!)
• Click on Send in the function to be tested and check whether the transmitted infor-
mation reaches the central station and shows the desired reaction. Data which are
normally linked via binary inputs (first character “>”) are likewise indicated to the
central station with this procedure. The function of the binary inputs itself is tested
separately.
Exiting the Test
Mode
To end the System Interface Test, click on Close. The device is briefly out of service
while the start-up routine is executed. The dialogue box closes.
Test in Command
Direction
The information transmitted in command direction must be indicated by the central
station. Check whether the reaction is correct.
3.3.3 Checking the Binary Inputs and Outputs
Prefacing Remarks The binary inputs, outputs, and LEDs of a SIPROTEC
®
4 device can be individually
and precisely controlled using DIGSI
®
. This feature is used to verify control wiring from
the device to plant equipment during commissioning. This test option should however
definitely not be used while the device is in service on a “live” system.
DANGER!
Danger evolving from operating the equipment (e.g. circuit breakers, discon-
nectors) by means of the test function
Non-observance of the following measure will result in death, severe personal injury
or substantial property damage.
Equipment used to allow switching such as circuit breakers or disconnectors is to be
checked only during commissioning. Do not under any circumstances check them by
means of the testing mode during “real” operation performing transmission and recep-
tion of messages via the system interface.
Note
After termination of the hardware test, the device will reboot. Thereby, all annunciation
buffers are erased. If required, these buffers should be extracted with DIGSI
®
prior to
the test.
The hardware test can be done using DIGSI
®
in the online operating mode:
• Open the Online directory by double-clicking; the operating functions for the device
appear.
•Click on Test; the function selection appears in the right half of the screen.
• Double-click in the list view on Hardware Test. The dialog box of the same name
opens (see the following figure).
