Details
These attributes are used to read or write to the operation status instrument summary registers. Reading a status
register returns a value. The binary equivalent of the returned value indicates which register bits are set. The
least significant bit of the binary number is bit B0, and the most significant bit is bit B15. For example, if a value
of
1.03
(which is 1,026) is read as the value of the condition register, the binary equivalent is
0000 0100 0000 0010. This value indicates that bit B1 and bit B10 are set.

For information about .condition, .enable, .event, .ntr, and .ptr registers, refer to
(on
Enable and transition registers
(on page E-19). The individual bits of this register are defined in
the following table.
Bit Value
Description
B0
Not used
Not applicable.
B1
status.operation.instrument.SMUA
Set bit indicates one or more
enabled bits for the operation
status SMU A summary register is
set.
Bit B1 decimal value: 2
B2-B9
Not used
Not applicable.
B10
status.operation.instrument.TRIGGER_BLENDER
status.operation.instrument.TRGBLND
Set bit indicates one or more
enabled bits for the operation
status trigger blender summary
register is set.
Bit B10 decimal value: 1,024.
B11
status.operation.instrument.TRIGGER_TIMER
status.operation.instrument.TRGTMR
Set bit indicates one or more
enabled bits for the operation
status trigger timer summary
register is set.
Bit B11 decimal value: 2,048
B12
status.operation.instrument.DIGITAL_IO
status.operation.instrument.DIGIO
Set bit indicates one or more
enabled bits for the operation
status digital I/O summary register
is set.
Bit B12 decimal value: 4,096
B13
status.operation.instrument.TSPLINK
Set bit indicates one or more
enabled bits for the operation
status TSP-Link summary register
is set.
Bit B13 decimal value: 8,192
B14
status.operation.instrument.LAN
Set bit indicates one or more
enabled bits for the operation
status LAN summary register is set.
Bit B14 decimal value: 16,384
B15
Not used
Not applicable.
As an example, to set bit B1 of the operation status instrument summary enable register, set
status.operation.instrument.enable
= status.operation.instrument.SMUA
.
In addition to the above constants,
operationRegister
can be set to the numeric equivalent of the bit to set.
To set more than one bit of the register, set
operationRegister
to the sum of their decimal weights. For
example, to set bits B1 and B10, set
operationRegister
to 1,026 (which is the sum of 2 + 1,024).
