1 Scope

Relations section 1.1 and IEC standards GB/T 31230 in this section depends on the IEC 61158 series of 12 file types in the corresponding section. 1.2 Overview EtherCAT Data link layer portion of the common elements to provide time critical information and communication between the automation equipment. "Time-critical" a Words denoting the presence of a time window within this time window required to complete one or more clearly defined specific action. Is not completed within the time window means Given action, it may result in the need for the action failed applications, and even affect the equipment, plant and personal safety. This section defines the abstract manner provided by EtherCAT Fieldbus Data Link Layer externally visible service, which by means of. a) service primitive actions and events; b) the primitive actions and events related to the parameters and the format they use; c) the relationship between actions and events and their effective sequence. The purpose of this section is to define the following two services offered. a) between the fieldbus reference model for the application layer and the data link layer, application layer EtherCAT bus at the border; b) systems management data link layer of the fieldbus reference model and system management boundaries. 1.3 specification The main purpose of this section is to define the appropriate time critical communication in the data link layer conceptual service characteristics, and as a complement to OSI Basic Reference Model, to guide the development of services in the critical time communication data link protocol; secondly, in order from existing industrial communication protocols The proposed open up the path. This part can be used as an official in accordance with DL programming interface. However, it is not a formal programming interface, the interface requires no formal solution This specification must realize the problem is not covered, including. a) sorting various multi-octet size and service parameters of octets; b) a pair of the request and confirm, or indication and response primitives as well as the correlation between. 1.4 Consistency This section does not specify individual devices or products, nor the specific provisions of industrial automation systems the data link layer entity. Although there is no consistency in this part of the device, however, the corresponding satisfy this section EtherCAT Data link layer service through the implementation of Defined data link layer protocol implementation conformance.
