Disturbance recorder

Disturbance data are uploaded and displayed in accordance with the IEC
recommendation with the following exceptions:
• REB500 supports a maximum of 15 records per Bay Unit, but only the first
(oldest) eight in the queue can be displayed in accordance with the
recommendation.
• Of the records that are displayed, only the oldest can be deleted or uploaded.
This is determined by the REB500 principle.
The time stamp invalid bit (IV) in a disturbance record is always set, because
the CIM module is unaware of the synchronization status at the instant of the
record.
The upload of disturbance data from the central unit is not possible
via IEC 60870-5-103.
Creating an export file
HMI500 provides facility for exporting the IEC 60870-5-103 communication data
contained in the system database in the form of a text file (export file). To do this,
select "Tools / Export SCS data" and IEC 60870-5-103 IBB and then click on the
"Export" button.
The application creates a text file (export file) iec103exp.lst, which contains all the
information required.
The file has the following structure:
1. Disturbance recorder signal configuration
2. IEC 60870-5-103 events
