ABB AC900F学习笔记43：Freelance_Mounting_and_Installation_AC_900F_Controller-3

接着学习文档。先吐槽一下，我在转到某浪自己的博客时，居然说有敏感词，真是活久见。

1.2 Communication

通讯

1.2.1 System

系统

TCP/IP, UDP/IP
       The Control Net (Ethernet) connects the individual stations with each other. It transfers data between the controllers and between Freelance Operations, the gateways and Freelance Engineering. The AC 900F controller supports data sending and receiving through TCP/IP (Ethernet-based sending/receiving) and/or UDP/IP (lateral communication). Additional application layers can be implemented by downloading them on the controllers. Simultaneous operation of TCP/IP, UDP/IP  and application layer is also ensured.

      控制网络（以太网）将各个站连接起来。它在控制器和freelance操作员站、网关、工程师站之间传输数据。AC900F支持通过TCP/IP 和/或 UDP/IP发送和接收数据。通过下载到控制器来实现附加应用层。TCP/IP、UDP/IP和应用层的操作同时实现。

     The data distribution at the bus is based on the Ethernet switch. The max. data transmission rate is 10 Mbit/s for 10 Base T and max. 100 Mbit/s for Fast-Ethernet.

     分布于总线上的数据基于以太网交换。星形联网拓扑结构（10 Base T)最大的数据传输速率是10 Mbit/s，快速以太网的传输速率是100Mbits/s.

     Twisted pair cables with RJ45 connector are used as transmission medium. The maximum cable length is 100 m at a maximum transmission speed of Mbit/s.

     RJ45双绞线作为传输介质，在100MBits/s速率下最远传输距离是100米。

     Detailed diagnostic messages for rapid fault localization can be retrieved via the diagnostic interface and/or the Freelance Engineering software。

    通过诊断接口和/或freelance工程师软件，可以快速定位诊断信息的细节。

 

1.2.2 Fieldbusses

现场总线

PROFIBUS®

      PROFIBUS-DP is designed for rapid data exchange in the field area. Central control units communicate with decentralized field devices like remote I/O, transmitters or drives etc. using a fast serial connection. The data exchange with the distributed modules is mainly performed on a cyclic basis. PROFIBUS-DP is optimized in terms of high speed and simple device connection. This protocol variant is specifically designed for the communication between programmable controllers and a distributed I/O level. The AC 900F controller supports PROFIBUS Master redundancy.

        PROFIBUS-DP设计用于现场区域的快速数据交换。中央控制单元和分散现场设备——远程IO、变送器或者驱动等等——进行通讯。使用快速串口连接。在周期基础上执行和分布式模板的数据交换。PROFIBUS-DP在高速和简单设备连接上进行了优化。此协议变体专为可编程控制器与分布式 I/O 级别之间的通信而设计.AC900F控制器支持作为PROFIBUS主的冗余。

      For additional information on PROFIBUS-DP and the PROFIBUS CI/CM modules,please refer to Section 3, Modules as well as to the Engineering Manual,Communication and Fieldbusses.

      有关 PROFIBUS-DP 和 PROFIBUS CI/CM 模块的更多信息，请参阅第 3 节、模块以及工程手册、通信和现场总线。

 

Modbus

       Numerous automation systems support the Modbus protocol by default or as an optional feature. This ensures easy communication with the AC 900F process station via on-board SER interfaces using the RS232/RS485 standards (MODBUS®) or TCP/IP (MODBUS TCP®). The Modbus protocol also ensures process data exchange with other systems via the serial or the Ethernet interfaces of the AC 900F.

     多数控制系统默认支持Mdubus协议或者将其作为可选项。这确保了通过板载接口以RS232/RS485或者TCPIP与AC900F做MODBUS通讯。MODBUS协议确保了通过AC900F上的串口或者以太网接口与其他系统的过程数据交换。

    This protocol allows data to be transmitted in either master or slave mode. For the configuration with serial interface, a specific MODM_DEV interface object must be assigned in the hardware structure. The interface-specific parameters are defined in this block.

    协议允许数据以主或者从模式传输。对于串口配置，必须在硬件结构中分配MODM_DEV接口对象。界面特定参数在此块中进行定义。

    For the TCP configuration (Ethernet), a specific MTCP_DEV interface object must be assigned in the hardware structure。

    对于TCP配置（以太网），必须在硬件结构中分配特定的MTCP_DEV接口对象。

    Please refer to the Engineering Manual, Communication and Fieldbusses and the Engineering manual, System Configuration, Hardware Structure for more detailed information.

     有关详细信息，请参阅《工程手册》、《通信和现场建设手册》和《工程手册》、《系统配置》、《硬件结构》

 Telecontrol protocol

远程控制协议

 

       The function blocks of the Telecontrol library are designed for the connection between the Freelance Engineering tool and external systems. The link is made via the serial interface (RS-232) or the Ethernet interface of the CPU module. The Telecontrol protocol complying to IEC 60870-5-101 (serial)/IEC 60870-5-104 (TCP/Ethernet) is used. 

      远程控制库的函数功能块设计用于freelance工程工具和外部系统的连接。该链接通过串行接口 （RS-232） 或 CPU 模块的以太网接口进行。远程控制协议符合IEC 60870-5-101 (serial)/IEC 60870-5-104 (TCP/Ethernet) 。

      For the serial interface, the Telecontrol protocol provides device modules for symmetrical data transmission (FWK_DEV), asymmetrical data transmission as a master (FWK_DEV_M) and asymmetrical data transmission as a slave (FWK_DEV_SL). These modules are configured in the hardware structure. Please refer to the Engineering Manual, System Configuration, Hardware Structure for more detailed information.

     对于串口，远程控制协议为对称数据传输 （FWK_DEV）、主不对称数据传输（FWK_DEV_M）和从不对称数据传输(FWK_DEV_SL)提供设备模块。这些模块在硬件结构中进行配置。有关详细信息，请参阅《工程手册》、《系统配置》、《硬件结构》。

     For Ethernet-supported communication, the Ethernet interface and the parameters of the IEC 60870-5-104 compliant protocol must be set in the FWK_DEV_104 function block designed for Telecontrol connection in the Ethernet network. The FWK_DEV_104 device module can be configured in the hardware structure below the Ethernet interface of the AC 900F.

     对于以太网支持的通讯，以太网接口和IEC 60870-5-104合规协议的参数必须设置在FWK_DEV_104函数功能块，FWK_DEV_104设备模块可配置在 AC 900F 以太网接口下方的硬件结构中。

ABB CAN Bus protocol

ABB CAN总线协议

     The CAN Bus of the AC 900F controller is intended to be used for connecting rackbased Freelance I/O modules only. With this feature, all CPU module types of AC 900F can alternatively take over the tasks of the CPU module types DCP 02/10 of the Freelance rack system.

    AC 900F 控制器的 CAN 总线仅用于连接基于机架的freelance  I/O 模块。借此功能，AC 900F 的所有 CPU 模块类型都可以替代freelance机架系统的 CPU 模块类型 DCP 02/10 的任务
