Bit
Value and description
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:
1.29000e+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).
