4 2QOLQH directory is opened with a double-click, the operating func-
If the DIGSI
tions for the device appear in the navigation window (Figure 7-2). By double clicking
on $QQXQFLDWLRQ, the tree structure expands and shows the individual message
groups. The groups are described in detail below.
The SCADA interface (if available) is generally connected to a RTU, SAS, Station
Computer or directly to a SCADA system. RS232, RS485, and multimode fiber optic
connections are available. Real-Time monitoring and breaker control are availble via
the SCADA interface.
The messages are categorized as follows:
• Event Log: These are message that can occur during the operation of the device.
They include information about the status of device functions, measurement data,
system data, recording of control commands, and similar information.
• Trip Log: Fault messages are message from the last 8 network faults that were pro-
cessed by the device.
• Sensitive Groung Fault Log: Ground fault messages, if the device has sensitive
ground fault detection.
• Statistics: These values include a counter for the trip commands initiated by the de-
vice, accumulated currents interrupted by the individual poles of the circuit breaker,
and the operating hours of the network or equipment being protected.
A complete list of all message and output functions that can be generated by the de-
vice, with the associated information number (FNo), can be found in Section A.5 of the
Appendix. The lists also indicate where each message can be sent. The lists are

are not present in the specific version of the device, or if they are set as "'LVDEOHG"
in Device Configuration, then the associated messages cannot appear.
The Event Log contains operating messages that the device generates during opera-
tion. All operating messages are stored in the Annuncitaion Logs. Up to 200 operat-
ing messages are recorded in chronological order in the device. New messages are
added at the end of the list. If the memory has been exceeded, then the oldest mes-
sage is written-over for each new message.
Faults in the power system are indicated with "1HWZRUN )DXOW" and the present fault
number. The 7ULS /RJ contain details about the progressions of faults. This topic is
discussed in Sub-section 7.1.1.3.
Ground fault messages are indicated with "*URXQG )DXOW" and the present ground
fault number (only for devices with sensitive ground fault detection). The *URXQG
)DXOW /RJ contains details about the ground faults, associated with the sensitive
ground fault function. The topic is discussed in Sub-section 7.1.1.4.
All predefined operating messages are listed and explained in a table in the Appendix.
In a specific case, of course, only the appropriate messages appear in the display. The
appendix also shows whether the message is only issued as "ON" (to indicate an
event), or as "ON" (asserted) and "OFF" (deasserted) (to designate the beginning and
end of a condition).
