FALSE

When there is an alarm reported by AlarmStatus, then in_alarm is set to 1

suppressed via ManualMode, then in_alarm is set to

ALARM_NOTIFY_DISABLED.

nviInUse(unsigned

0 To 65535

0 to FFFF

InUse is used by a management node to indicate to all other management

long)

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.
