The data-link layer provides basic time-critical messaging communications between devices in an automation environment.
This protocol provides communication opportunities to a pre-selected ?master? subset of datalink entities in a cyclic asynchronous manner, sequentially to each of those data-link entities. Other data-link entities communicate only as permitted and delegated by those master data-link entities.
For a given master, its communications with other data-link entities can be cyclic, or acyclic with prioritized access, or a combination of the two.
This protocol provides a means of sharing the available communication resources in a fair manner. There are provisions for time synchronization and for isochronous operation.
