Parameter Default Value

Honeywell
Description
When this parameter is On
and the device is attached
to the network at one of the
default addresses, the NMA
regards the value as a
configuration value and
does not attempt to acquire
the LAS.
When this parameter is On
or it receives a FMS
Write.ind to turn it On from
the NMA of a Link Master
device that is not the LAS
and is at an assigned
address instead of a default
one on the network, the
NMA instructs the Data Link
Management Entity (DLME)
to acquire the LAS. The two
possible outcomes are as
follows.
f) If the DLME indicates that
the attempt failed, the NMA
sets the value of this
parameter to Off. If a FMS
write response is pending,
the NMA returns a negative
response.
g) If the request succeeds on
either the first or the second
attempt, the NMA sets the
value of the parameter to
On (if not On already). If an
FMS write response is
pending, the NMA returns a
positive response.
Specifies the Operational
Function Class that the device
assumes when it is powered up.
The class selections are Basic,
Link Master, and Bridge. The
