Status register sets
As shown 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
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
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
ters" 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:
•
•
Figure D-1 through
Figure D-1 and
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.
