Series 2600A System SourceMeter® Instruments Reference Manual
Appendix C: Status Model
Status register sets
As shown in
, there are five status register sets in the status
structure of the SourceMeter instrument; System Summary Event Status, Standard Event Status,
Operation Event Status, Measurement Event Status, and Questionable 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
.
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,
1
NODEn:
Indicates a bit on TSP-Link node n has been set (n = 1 to 64).
1.status.system5 does not use bits B9 through B15.
