ISO 11783-3-2018 农林拖拉机和机械--串行控制和通信数据网--第3部分:数据链路层 Tractors and machinery for agriculture and forestry — Serial control and communications data network — Part 3: Data link layer
This document specifies the application, the network layer protocols and the mapping to the controller area network (CAN) data link layer protocol as specified in ISO 11898-1. The application layer specifies protocol data units (PDU), which can be mapped to Classical CAN data frames using the Classical Extended Frame Format (CEFF). For PDUs exceeding the length of the CEFF-formatted data frames, this document specifies transport layer protocols and the mapping to CEFF-formatted data frames.

IEC 62325-451-4-2017 能源市场通信用框架--第451-4部分:欧洲市场用结算和对账业务流程、情境和装配模型 Framework for energy market communications - Part 451-4: Settlement and reconciliation business process, contextual and assembly models for European market
Based on the European style market profile (ESMP) (IEC 62325-351), this part of IEC 62325- 451 specifies a package for the settlement and reconciliation business process and the associated document contextual model, assembly model and XML schema for use within European style markets.<br /><br />The relevant aggregate core components (ACCs) defined in IEC 62325-351 have been contextualised into aggregated business information entities (ABIEs) to satisfy the requirements of this business process. The contextualised ABIEs have been assembled into the relevant document contextual models. Related assembly models and XML schema for the exchange of information between market participants are automatically generated from the assembled document contextual models.<br /><br />This part of IEC 62325 provides a uniform layout for the transmission of aggregated data in order to settle the electricity market. It is however not the purpose of this document to define the formula to be taken into account to settle or reconcile a market. The purpose of this document is only to enable the information exchange necessary to carry out the computation of settlement and reconciliation. The settlement process or reconciliation process is the way to compute the final position of each market participant as well as its imbalance amounts.
