SECTION 4
STATUS STRUCTURE
4-3
The Status Byte (STB) sent to the controller is based on the IEEE488.1 standard. The
bits comprising the STB are called status summary messages because they represent a
summary of the current data in registers and queues.
IEEE488.2 Standard Status Model
The diagram below shows the standard model for the status data structures stipulated
in the IEEE488.2 standard.
