can be granted only when the remaining time is higher than DefMinTokenDelegTime. The parameter is specified in octet durations.

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

TargetToke the configured value for TargetTokenRotTime the LAS nRotTime 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.

This parameter specifies the time that the LAS uses LinkMaintTo within a token rotation for link maintenance which is kHoldTime probing for new node addresses and sending LAS

status frames.

Time Distribution PDU's will be sent on the bus in 95% or less of that time period. The parameter is specified in milliseconds.

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.

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.

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.
