7.1 Retrieval of Information
General The device provides information that can be obtained locally or remotely:
•
Messages,
•
Operating measurement and metered values,
•
Waveform data in oscillographic records.
This information is individually discussed below. Methods for viewing, retrieving, ac-
knowledging, and storing this information on a PC are also explained.
7.1.1 Messages
7.1.1.1 Output of Messages
Messages provide operating information about the power system, the device, and the
measurements. Other messages give an overview of important events such a network
fault and the operation of device functions. The information provided is useful in
checking overall operation of the device during testing and commissioning.
Password entry is not required to read messages.
The messages generated in the device can be presented in various ways:
•
Display using light-emitting diodes (LEDs) on the front of the device,
•
Operation of binary outputs connected to external signaling equipment,
•
Display in the LCD on the front of the device,
•
Displayed in DIGSI
®
4 program, connected to the front or rear DIGSI serial interface
port on the device,
•
Transfer to a SCADA via SCADA port.
Light-Emitting
Diodes The green light-emitting diode with the label “RUN” lights continuously during normal
operation.
The red LED with the label “ERROR” indicates that the processor system has recog-
nized an internal problem. If this LED is on, then the device is not in operation. Chapter
9 discusses steps to take if a failure occurs in the device.
The other LEDs on the front of the device display the messages in accordance with
the masking, as discussed in Chapter 5. The description of each LED illumination
should then be indicated on the label strips.
Latched LEDs can be reset by the LED key . This key simultaneously serves as a
functional check for all of the LEDs except the “RUN” and “ERROR” LEDs. While the
key is pressed, all of these LEDs must light.
LEDs that display a condition light for as long as the condition is maintained if not
latched. The LED action is therefore generally not stored, but erased as soon as the
condition vanishes. Of course, these LEDs are also included in the function check with
the LED key
