GE EPM 9650/9800 manual

The designation “first 128 bytes of the log” is a physical description based on the absolute address- es of the memory allocated to the log. The first (oldest) record in the log may not be located at the beginning of the log.

In Time Stamp Modes (0x00001 and 0x00003), the Historical Log 1 Window accesses the Time Stamps of the records in the Historical Log 1 in blocks of 16 Time Stamps at a time. When the Index = 0x00000, the Time Stamps of the first 16 records (records 0-15) in the log are readable in the window; when the Index = 0x00001, the Time Stamps of the second 16 records (records 16-31) in the log are readable in the window, and so on.

The designation “first 16 records of the log” is a physical description based on the absolute addresses of the memory allocated to the log. The first (oldest) record in the log may not be locat- ed at the beginning of the log.

In Paused Modes (0x00000 and 0x00001), the log being accessed is paused and new records are not added to the log while it is paused.

In Running Modes (0x00002 and 0x00003), the log being accessed is not paused and new records may be added to the log. When downloading in these modes, it is possible the records may be overwritten before or during the downloading of records.
