Record Data Acquisition Primitive Codes 55 56 57
The Record Data Acquisition Primitives allow repetitive collection of multiple predefined blocks of data. The Define Record Primitive (55) allows multiple blocks of data to be
defined as a single record. The Gather Record Primitive (56) collects the data blocks for
the requested records. The Write and Gather Record Primitive (57) combines the functions of the Write Block Primitive (30) and the Gather Record Primitive (56).
The record definitions are destroyed in the event of a power loss or a
hardware reset or HDLC DISC command. Any initialization or re-initialization procedures must use the Define Record Primitive (55) to re-define the data acquisition records.
