|---|---|
| 时间偏移 time offset | time difference from a specially designated time(从特殊指定时间的时间差) |
| 通信宏周期 communication macrocycle | set of basic cycles needed for a configured communication activity in a macro network segment(宏观网段中为配置的通信活动所需的基本周期集合) |
| 通信阶段 communication phase | elapsed fraction of a cycle, measured from some fixed origin(从某个固定原点测量的周期的经过部分) |
| 通信调度 communication scheduling | algorithms and operation for data transfers occurring in a deterministic and repeatable manner(以确定性和可重复方式发生的数据传输的算法和操作) |
| 周期性 cyclic | repetitive in a regular manner(以规则方式重复) |
| 数据 DLPDU data DLPDU | DLPDU that carries a DLSDU from a local DLS-user to a remote DLS-user(从本地DLS用户传输到远程DLS用户的DLPDU) |
| 目的FB实例 destination FB Instance | FB instance that receives the specified parameters(接收指定参数的FB实例) |
| DL段链接 DL-segment link | local link; single DL-subnetwork in which any of the connected DLEs may communicate directly, without any intervening DL-relaying, whenever all of those DLEs that are participating in an instance of communication are simultaneously attentive to the DL-subnetwork during the period(s) of attempted communication(本地链接;单个DL子网,其中任何连接的DLE都可以直接通信,无需任何干预的DL中继,只要所有参与通信实例的DLE在尝试通信期间同时关注该DL子网) |
| 数据链路服务访问点 DLSAP | distinctive point at which DL-services are provided by a single DL-entity to a single higher-layer entity(单个DL实体向单个高层实体提供DL服务的特征点) |
| DL(SAP)地址 DL(SAP)-address | either an individual DLSAP-address, designating a single DLSAP of a single DLS-user, or a group DL-address potentially designating multiple DLSAPs, each of a single DLS-user(单个DLSAP地址或组DL地址,可能指定多个DLSAP) |
| FCS错误 FCS error | error that occurs when the computed frame check sequence value after reception of all the octets in a DLPDU does not match the expected residual(当接收DLPDU中所有八位组后计算的帧检查序列值与预期残差不匹配时发生的错误) |
| 微段 micro segment | part of a network, where special scheduling is implemented(实施特殊调度的网络部分) |
| 多点连接 multipoint connection | connection from one node to many nodes(从一个节点到多个节点的连接) |
| 节点 node | single DL-entity as it appears on one local link(本地链路上出现的单个DL实体) |
| 偏移 offset | number of octets from a specially designated position(从特殊指定位置的八位组数) |
| 实时 real-time | ability of a system to provide a required result in a bounded time(系统在有限时间内提供所需结果的能力) |
| 实时通信 real-time communication | transfer of data in real-time(实时数据传输) |
| 实时以太网 real-time Ethernet | ISO/IEC 8802-3-based network that includes real-time communication(包含实时通信的ISO/IEC 8802-3网络) |
| 接收DLS用户 receiving DLS-user | DL-service user that acts as a recipient of DL-user-data(作为DL用户数据接收方的DL服务用户) |
| 调度 schedule | temporal arrangement of a number of related operations(一系列相关操作的时间安排) |
| 调度宏周期 scheduling macrocycle | time interval to implement a specific schedule(实施特定调度的时间间隔) |
| 发送DLS用户 sending DLS-user | DL-service user that acts as a source of DL-user-data(作为DL用户数据源的DL服务用户) |
