7. PQ Event Log (10): The Power Quality Event log records the information regard-
ing Shark® 200 meter trigger conditions, including the cause of the trigger, condi-
tions at the time of the trigger, and duration of the event.
8. Waveform Log (11): The waveform log records the waveform samples of a
capture, along with information about the capture. Due to the large amount of
data involved in a waveform capture (approximately 24kb), a single waveform
capture is split over 26 log records. All 26 of these records must be retrieved to
build up the single capture. Every waveform record contains a: record header, cap-
ture number, record number and record payload.

B.5.3: Block Definitions

This section describes the Modbus Registers involved in retrieving and interpreting a
Shark® 200 Meter Log. Other sections refer to certain 'values' contained in this sec-
tion. See the corresponding value in this section for details.
NOTES:
• "Register" is the Modbus Register Address in 0-based Hexadecimal notation. To
convert it to 1-based decimal notation, convert from hex16 to decimal10 and add
1. For example: 0x03E7 = 1000.
• "Size" is the number of Modbus Registers (2 byte) in a block of data.

Historical Log Programmable Settings:

The Historical Logs are programmed using a list of Modbus Registers that will be cop-
ied into the Historical Log record. In other words, Historical Log uses a direct copy of
the Modbus Registers to control what is recorded at the time of record capture.
To supplement this, the programmable settings for the Historical Logs contain a list of
descriptors, which group registers into items. Each item descriptor lists the data type
of the item, and the number of bytes for that item. By combining these two lists, the
Historical Log record can be interpreted.
