Test in Message Di-
rection For all information that is transmitted to the central station, test the options in the list
which appears in
SETPOINT Status :
• 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 power system 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 dialog 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 Status of Binary Inputs and Outputs
Prefacing Remarks The binary inputs, outputs, and LEDs of a SIPROTEC 4 device can be individually and
precisely controlled in DIGSI. This feature is used to verify control wiring from the
device to plant equipment (operational checks), 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 test function during real operation by transmitting or receiving messages
via the system interface.
Note
After finishing the hardware test, the device will make an initial startup. Thereby, all an-
nunciation buffers are erased. If required, these buffers should be extracted with
DIGSI prior to the test.
