can be granted only when the remaining time is higher
than DefMinTokenDelegTime. The parameter is
specified in octet durations.
TargetToke
nRotTime
This parameter specifies the target time in which all
devices have been given the token for acyclic data
transfer. If the actual token rotation time is higher than
the configured value for TargetTokenRotTime the LAS
will increase the token priority. So a value of
TargetTokenRotTime that is too small could mean that
no client/server or SM service can be transmitted as
these are using the lowest priority.

60000
LinkMaintTo
kHoldTime
This parameter specifies the time that the LAS uses
within a token rotation for link maintenance which is
probing for new node addresses and sending LAS
status frames.
292 - 65000
336
TimeDistrib
utionPeriod
Time Distribution PDU's will be sent on the bus in 95%
or less of that time period. The parameter is specified in
milliseconds.
10 - 55000
5000
MaximumIn
activityToCl
aimLasDela
y
This parameter specifies the internal delay time a Link
Master device needs from the detection of the failure of
a LAS to the time the Link Master sends a ClaimLAS
request. When configuring the link the minimum value
for this parameter is determined by the highest value of
all Link Master devices in the link.

Distribution
Period
The LAS Live list database of the link will be distributed
in that time period to other LAS or link master devices
on the link. The parameter is specified in milliseconds.
A value of 1000 - 5000 is recommendable.
100 - 55000
5000
TimeSyncCl
ass
This parameter defines the quality of the clock accuracy
of a device. Thus it also defines the periods for time
synchronization because a device with a more
inaccurate clock should be synchronized more often.
The maximum value a device is capable of supporting
is described in the device's CFF file. When configuring
a link, the maximum value should be set according to
the minimum value of the used devices.

FirstUnpolle
dNodeId
(FUN)
The node address of the first node that will not be
polled by the LAS of the link.
FUN >= 20
AND
FUN + NUN - 1
<= 247.
248
NumConsec
UnpolledNo
deId (NUN)
Range of consecutive node addresses that are not
polled by the LAS of the link.
FUN >= 20
AND
FUN + NUN - 1
<= 247.

Ranges and/or restrictions denoted with the column Range/Restriction above will
be checked by the FF-CONF and an appropriate error message will be issued if
the range/restriction is violated.
