If the SIPROTEC 4 device is connected to a central or master computer system via
the system interface, then the information that is transmitted can be influenced (see
Table "Protocol-dependent functions" in the Appendix A.13).
If Test mode is set ON, then a message sent by the device to the master system has
an additional test bit. This bit allows the message to be recognized as resulting from
testing and not an actual fault or power system event.
If DataStop is set ON, transmission to the master station is blocked.
The procedures for setting Test mode and DataStop are described in SIPROTEC
4 System Manual. Note that when DIGSI

If the device provides a system interface, and if this interface is used to communicate
with a central or master computer system, the DIGSI
whether the messages are being transmitted correctly. This test option should
however definitely not be used while the device is in service on a live system.
DANGER!
The initiation or extraction of messages via the system interface using the test
function constitutes an actual exchange of information between the device and
the control system. Connected plant such as e.g. circuit breakers or isolators
may be switched as a result of this!
Note: After termination of the test mode, the device will reboot. Thereby, all
annunciation buffers are erased. If required, the events in these buffers should be

extracted with DIGSI 4 prior to the test.

to Figure 3-17).
In the column Indication, the display text of all messages are shown, which were
assigned to the system interface in the matrix during configuration. In the column
SETPOINT status the state of the message that has to be tested can be defined.
Depending on the message type, different prompts are provided for this purpose (e.g.
event coming/event going). By clicking in a field, it becomes possible to select
the desired state in a pull-down list.
