Operation Manual 31
Distributed busbar protection REB500
3.5.8.2 Load events
The protection system has an event memory for every unit (central unit and bay
units).
To upload the latest events to the PC, open the “View” menu and select “Event
list”. This opens the “Event list” dialog (HMI500 must be in the on-line mode).
Click on the “Refresh“ button to upload the events. The protection system stores
the events until they are explicitly deleted.
The list viewed on the PC is refreshed either on command or cyclically.
There is no indication should the event memory overflow before the events have
been uploaded. The events are updated as determined by the system response
setting (see “Technical Reference Manual”).
The following information is shown for every event:
• Type of event
• P = Protection function event
• S = System event
• T = Test generator event
• Date event occurred
• Time event occurred
• Time tag valid (yes / no)
• Source of event with application device ID in the format
FFFAAAAAA (e.g. BPD000011):
• FFF: English function designation
• AAAAAA: Address of the hardware unit that generated the event.
The source data are important for locating hardware defects.
• Text as entered via “Configuration/Binary inputs/outputs” (user defined) or
alternatively, the name assigned by the system (system defined)
• Value, e.g. ON or OFF.
The width of the columns can be adjusted by dragging the border with the mouse in
the table header.
Providing a printer is connected to the PC, you can print the event list by clicking
on “Print”. The event list can be saved in a text file on the PC with the aid of
“ASCII export”.
