Before you can use the information in this chapter you must be familiar with
and understand the information and the concepts described in
“Historical Data” on
page - 114.
The following table shows an overview of the mapping table:
Log type Details Start Reg (Hex) Size
System log Header 6500 16
System log Data block 6510 105
Event log Header 65B0 16
Event log Data block 65C0 105
Net quality log Header 6710 16
Net quality log Data block 6720 105
There is one pair of header and data block for each log type, located in the
registers listed in the mapping table above. In the tables showing the structure
of the header and data block below the register numbers are valid for the
System log. However the headers and data blocks for all log types share the
same structure, so the tables are applicable for all log types if the register
numbers are exchanged to correct values.
