status.node_enable
Attribute Status node enable register.
Default 0
TSP-Link
accessibility
This attribute can be accessed from a remote TSP-Link node.
Usage Reads status node enable register:
nodeenabreg = status.node_enable
Writes to system enable register:
status.node_enable = nodeenabreg
Set nodeenabreg to one of the following
values:
0
status.MEASUREMENT_SUMMARY_BIT
status.MSB
status.ERROR_AVAILABLE
status.EAV
status.QUESTIONABLE_SUMMARY_BIT
status.QSB
status.MESSAGE_AVAILABLE
status.MAV
status.EVENT_SUMMARY_BIT
status.ESB
status.MASTER_SUMMARY_STATUS
status.MSS
status.OPERATION_SUMMARY_BIT
status.OSB
Clears all bits.

Sets (enables) EAV bit (B2).
Sets (enables) EAV bit (B2).
Sets (enables) QSB bit (B3).
Sets (enables) QSB bit (B3).

Sets (enables) MAV bit (B4).
Sets (enables) ESB bit (B5).
Sets (enables) ESB bit (B5).
Sets (enables) MSS bit (B6).
Sets (enables) MSS bit (B6).
Sets (enables) OSB bit (B7).
Sets (enables) OSB bit (B7).
nodeenabreg can also be set to the decimal weight of the bit to be set. Examples:
To set bit B0 (MSB), set nodeenabreg to 1 (2
0
).
To set bit B2 (EAV), set nodeenabreg to 4 (2
2
).
To set bit B7 (OSB), set nodeenabreg to 128 (2
7
).
To set more than one bit of the register, set nodeenabreg to the sum of their decimal
weights. For example, to set bits B0 and B7, set nodeenabreg to 129 (1 + 128).
Remarks • This attribute is used to read or write to the status node enable register.
• Reading the node enable 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 0, and the most significant bit is Bit 7.
• For example, assume the value 129 is returned for the node enable register. The binary
equivalent is 10000001. This value indicates that bit B0 (MSB) and bit B7 (OSB) 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.
• The status node enable register uses most of the same summary events as the status
byte. Bit B1(MSB) is not used, and bit B6 is used as Master Summary Status (MSS). For
details, see
status.condition register.
Details See Status byte and service request (SRQ) in Appendix C.
Example Sets the MSB bit of the status node enable register:
status.node_enable = status.MSB
