The returned value can indicate one or more status events occurred.
Bit Value Description
B0
status.MEASUREMENT_SUMMARY_BIT
status.MSB
Set summary bit indicates that an enabled
measurement event has occurred.
Bit B0 decimal value: 1
B1
Not used Not applicable
B2
status.ERROR_AVAILABLE
status.EAV
Set summary bit indicates that an error or status
message is present in the error queue.
Bit B2 decimal value: 4
B3
status.QUESTIONABLE_SUMMARY_BIT
status.QSB
Set summary bit indicates that an enabled
questionable event has occurred.
Bit B3 decimal value: 8
B4
status.MESSAGE_AVAILABLE
status.MAV
Set summary bit indicates that a response message
is present in the output queue.
Bit B4 decimal value: 16
B5
status.EVENT_SUMMARY_BIT
status.ESB
Set summary bit indicates that an enabled standard
event has occurred.
Bit B5 decimal value: 32
B6
status.MASTER_SUMMARY_STATUS
status.MSS
Set bit indicates that an enabled Master Summary
Status (MSS) bit of the Status Byte register is set.
Bit B6 decimal value: 64
B7
status.OPERATION_SUMMARY_BIT
status.OSB
Set summary bit indicates that an enabled operation
event has occurred.
Bit B7 decimal value: 128
In addition to the above constants,
nodeEventRegister
can be set to the decimal equivalent of the
bits set. When more than one bit of the register is set,
nodeEventRegister
contains the sum of
their decimal weights. For example, if 129 is returned, bits B0 and B7 are set (1 + 128).

Example
nodeEventRegister = status.node_event
print(nodeEventRegister)
Reads the status node event register.
Sample output:
1.02
Converting this output (129) to its binary equivalent yields
1000 0001
. Therefore, this output indicates that the
set bits of the status byte condition register are presently B0 (MSB) and B7 (OSB).
