FALSE When there is an alarm reported by AlarmStatus, then in_alarm is set to 1
(TRUE), else in_alarm is set to 0 (FALSE). If alarms reporting is
suppressed via ManualMode, then in_alarm is set to
ALARM_NOTIFY_DISABLED.
nviInUse(unsigned
long)
0 To 65535 0 to FFFF InUse is used by a management node to indicate to all other management
nodes that it is logged on to the Excel 10 node and that they should not try
to interact with any of the Excel 10s network variables. Before the
management node reads or writes any network variables, the management
node checks nviInUse for a zero value meaning no other management
nodes are already logged on and that a management node may log on to
the node. Then the management node writes a number, 1 through 65534,
to nviInUse and periodically writes the same value to indicate that the
management node is still logged on. If there are no writes made to
nviInUse for approximately 60 seconds, then the Excel 10 resets nviInUse
to zero to automatically log off the management node. Before interacting
with any network variables, the management node verifies that the
nviInUse has not changed. The management node logs off by writing 0 to
nviInUse.During power up, an application restart, or return to on-line from
off-line, the Excel 10 sets InUse to 65535 to indicate to the management
node that it has returned to on-line.
