Status model diagrams
The register sets (and queues) monitor various instrument events. When an enabled event occurs in
one of the five registers, it sets the associated summary bit in the Status Byte register. When a
summary bit of the Status Byte is set and its corresponding enable bit is set (as programmed using
status.request_enable), the MSS bit will set to indicate that an SRQ has occurred. View the
master summary bit using status.condition attribute. In an expanded system (TSP-link), setting
the status.node_enable attribute allows the System registers to be shared by all nodes in the
TSP-Link system. The following figures and topics illustrate the relationships of the individual
registers and queues with the Status Byte register.
