Status register sets
As shown in
through
, there are five status register sets in
the status structure of the SourceMeter; System Summary Event Status, Standard
Event Status, Operation Event Status, Measurement Event Status, and Question-
able Event Status.
System Summary Event Registers
As shown in
, there are five register sets associated
with System Event Status. These registers summarize system status for various
nodes connected to the TSP-Link (see Section 9). Note that all nodes on the TSP-
Link share a copy of the system summary registers once the TSP-Link has been
initialized. This feature allows all nodes to access the status models of other
nodes, including SRQ.
In a TSP-Link system, the status model can be configured such that a status
event in any node in the system can set the RQS (Request for Service) bit of the
Master Node Status Byte. See
“
” in this appendix for
details on using the status model in a TSP-Link system.
Commands for the system summary registers are summarized in
For example, either of the following commands will set the EXT enable bit:
status.system.enable = status.system.EXT
status.system.enable = 1
When reading a register, a numeric value is returned. The binary equivalent of this
value indicates which bits in the register are set. For details, see “
” in this appendix.
For example, the following command will read the system
enable register:
print(status.system.enable)
The used bits of the system event registers are described as follows:
•
Bit B0, Extension Bit (EXT)
— Set bit indicates that an extension bit from
a another system status register is set.
• Bits B1-B14*, NODEn
— Indicates a bit on TSP-Link node n has been set
(n =1 to 64).
*
status.system5
does not use bits B9 through B15.
