Checking the Binary Inputs and Outputs
Prefacing Remarks
The binary inputs, outputs, and LEDs of a SIPROTEC
and precisely controlled in DIGSI
nection to the system during commissioning. This test option should however definite-
ly not be used while the device is in service on a „live" system.
DANGER!
The sending or receiving of indications via the system interface by means of the
test function is a real information exchange between the SIPROTEC device and
the control centre. Connected operating equipment such as circuit breakers or
disconnectors can be switched in this way!
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 indications via the system interface.
Note
After termination of the hardware test, the device will reboot. All annunciation buffers
are erased. If required, these buffers should be extracted with DIGSI

and LED for light-emitting diodes. On the left of each group is an accordingly labelled
panel. By double-clicking a button, information regarding the associated group can be
shown or hidden.
In the column Actual the present (physical) state of the hardware component is dis-
played. The display is made in symbols. The actual states of the binary inputs and
outputs are displayed by the symbol of opened and closed switch contacts, those of
the LEDs by a symbol of a lit or extinguished LED.
The opposite state of each element is displayed in the column Scheduled. The display
is made in plain text.
