    APPENDIX 5. LINK MASTER FUNCTIONS APPENDIX 5. LINK MASTER FUNCTIONS A5.1 Link Active Scheduler A link active scheduler (LAS) is a deterministic, centralized bus scheduler that can control communications on an H1 fieldbus segment. There is only one LAS on an H1 fieldbus segment. A YTA supports the following LAS functions.

  • Page 89: A5.3 Transfer Of Las

    APPENDIX 5. LINK MASTER FUNCTIONS A5.3 Transfer of LAS There are two procedures for an LM to become the LAS: • If the LM whose value of [V(ST) V(TN)] is the smallest on a segment, with the exception of the current LAS, judges that there is no LAS on the segment, in such a case as when the segment has started up or when the current LAS has failed, the LM declares itself as the LAS, then becomes the LAS.

    APPENDIX 5. LINK MASTER FUNCTIONS A5.4 LM Functions Function Description LM initialization When a fieldbus segment starts, the LM with the smallest [V(ST) V(TN)] value within the segment becomes the LAS. At all times, each LM is checking whether or not a carrier is on the segment.
