Retrieving historical records
Historical records are generated for four different events (see page 23). To find
the precise historical data location where the data cycle has been recorded, use
the following steps. This way data for any cycle number can be retrieved without
a search through all the historical records. The retrieval starts with a request
to 5302h to find the record number. (See also, chart at bottom of page 23.)
The Acuity response to this request is as follows.

After the historic record number is received, specific details for that record can
be retrieved, using the SDO object Historic Record Request (5300h), along
with the appropriate sub-index.
