medium.
This read-only parameter
indicates whether or not this
node is the acting primary Link
Master. A check mark in the
check box means that the node
is the acting primary Link
Master. A blank check box
means that the node is not the
acting primary Link Master.
Indicates whether or not this
node is the primary Link Master.
A check mark in the check box
means that the node is the
primary Link Master. A blank
check box means that the node
is not the primary Link Master.
A write to this parameter orders
the receiving Link Master to try
to become the Link Active
Scheduler (LAS). If the Link
Master becomes the LAS, it
returns an FMS Write.rsp(+),
which turns the flag On (check
mark). If this attempt fails, it
returns an FMS Write.rsp(-),
which keeps the flag Off (blank).
Notes:
It is a configuration error to
have more than one device
on a link configured as the
primary Link Master.
The FIM is the designated
primary Link Master for
both of its Links.
The value of this
parameter may only be set
to On (check mark) through
a FMS Write or a local
interface.
