Industrial communication networks. Fieldbus specifications - Data-link layer protocol specification. Type 24 elements1 Scope 1. 1 General The data link layer provides basic time critical messaging communications between devices in an automation environment. This protocol provides communication opportunities to all participating data link entities a) in a synchronously starting cyclic manner, according to a pre established schedule, or b) in an acyclic manner, as requested by each of those data link entities. Thus this protocol can be characterized as one which
