Status Data General
Structure
A single Read Element Status Data Header is returned along with one
or more element status pages. The Read Element Status Data Header
indicates the address of the first element reported, the number of
elements reported, and the size of the report for all requested data.
The size of the report is given in bytes. The size is the total number of
bytes that would be contained in the report for all requested data less
seven. The Read Element Status command can be given with an
Allocation Length of eight to determine how much space must be
allocated to transfer all of the status data requested by the command.
