Bit Value
Description
B0
Not used
Not applicable.
B1
status.measurement.voltage_limit.SMUA
Set bit indicates that the voltage limit was
exceeded.
Bit B1 decimal value: 2
Binary value: 0000 0010
B2-B15
Not used
Not applicable.
As an example, to set bit B1 of the measurement event voltage limit summary enable register, set
status.measurement.voltage_limit.enable = status.measurement.voltage_limit.SMUA
.
In addition to the above constant,
measurementRegister
can be set to the numeric equivalent of the bit to set.
Example
status.measurement.voltage_limit.enable =
status.measurement.voltage_limit.SMUA
Sets the SMUA bit of the
measurement event voltage limit
summary enable register using a
constant.

Usage
nodeEnableRegister
= status.node_enable
status.node_enable =
nodeEnableRegister
nodeEnableRegister
The status of the system node enable register; a zero (0) indicates no bits set (also
send 0 to clear all bits); other values indicate various bit settings
Details
This attribute is used to read or write to the system node enable register. Reading the system node enable
register returns a value. The binary equivalent of the value indicates which register bits are set. In the binary
equivalent, the least significant bit is bit B0, and the most significant bit is bit B7. For example, assume the value
of
1.02
(which is 129) is returned for the system node enable register, the binary equivalent is
1000 0001. This value indicates that bit B0 and bit B7 are set.

Assigning a value to this attribute enables one or more status events. When an enabled status event occurs, a
summary bit is set in the appropriate system summary register. The register and bit that is set depends on the
TSP-Link node number assigned to this instrument.
