2 通 信 透 明 从 传 感 器／执 行 器 到 区 域 控 制 器 工厂级 Ethernet/TCP/IP TCP/IP/Ethernet
PC/VME 总线 循环时间 < 1000 ms CNC 车间级 PROFIBUS-FMS VME/PC 总线 循环时间 < 100 ms PLC DCS PROFIBUS consists of 3 compatible variations. PROFIBUS-FMS is suitable for the communication between intelligent field devices like PLCs and PCs. PROFIBUS-FMS offers a wide range of powerful application services which meet the communication requirements between intelligent devices. PROFIBUS-DP is used for the communication between intelligent devices and the distributed I/Os. PROFIBUS-DP is very fast, very efficient and easy to use. PROFIBUS-FMS and PROFIBUS-DP operate on the same cable and are using the same transmission technology - so they can be combined in any way on the same cable. PROFIBUS-PA is dedicated to the process industry. PROFIBUS-PA uses the PROFIBUS-DP protocol and the IEC transmission technology. PA can operate in intrinsically safe areas and offers the possibility to power the field devices over the bus. Today, PROFIBUS is the only Fieldbus system offering a complete and proven solution for both manufacturing (H2) and process (H1). 现场级 PROFIBUS-DP PROFIBUS-PA 总线 循环时间 < 10 ms

PROFIBUS-FMS is the universal solution dedicated to the automation for general purposes. It offers a large variety of applications and it offers the possibility for multi-master communication between intelligent devices. PROFIBUS-DP is the solution especially dedicated to the factory automation. It is very fast, offers plug-and-play systems, and is efficient and cost-effective. PROFIBUS-PA is dedicated to process automation. It uses the PROFIBUS-DP protocol and the IEC transmission technology and offers the possibility to power the stations over the bus. The protocol functions of PROFIBUS are supplemented by profiles which describe how to use PROFIBUS in special application areas. Examples for device profiles are: drives, encoders, NC/RC. Branch profiles include the PROFIBUS-PA profile for instruments e.g. temperature, pressure, .... as well as profiles for building automation. Profiles are defined in the guidelines of PROFIBUS International. Application Profiles Device Profiles - 大 范 围 的 应 用 - 多 主 通 信 - 即 插 即 用 - 高 效、廉 价 - 总 线 供 电 - 本 质 安 全

4 PROFIBUS 是 国 际 性 的 开 放 的 现 场 总 线 标 准
EN 50170 PROFIBUS 是 国 际 性 的 开 放 的 现 场 总 线 标 准 PROFIBUS 标准 EN 是完整的、开放的、与制造商无关的、已经生效的 稳固的 PROFIBUS 标准保护世界范围的用户和制造商的投资 PROFIBUS 经实践证明并在世界范围内已安装使用的设备超过3,000,000 个。（截止于１９９９年3季度） The European standardization of PROFIBUS saves users' and vendors' investments. EN has been ratified by all 18 European countries and achieves world-wide acceptance. The standardization of PROFIBUS guarantees that the technology is open for everybody, vendor-independent and free of intellectual property rights. Today (Q1/98) EN contains the full specification of PROFIBUS-FMS and DP. In Q1/98 the Amendment 2 to EN has been issued for voting. This part describes the use of the IEC transmission technology for PROFIBUS. The voting will be finished in Q3/98. PROFIBUS International is actively supporting the IEC standardization with proven PROFIBUS technology. Since IEC standardization is mainly politically influenced, the future IEC Fieldbus Standard might not include all parts of the PROFIBUS technology and define a solution that will not fulfill the user requirements. Even in this case, the PROFIBUS technology will be kept stable and will be available for all users and vendors world-wide.

5 PROFIBUS 给客户的好处 节省硬件和安装费用 减少硬件成份 (I/O, 终端块、隔离栅) 更容易、更快捷和低成本的安装
节省工程费用 更容易组态(对所有设备只需一套工具) 更容易保养和维修 更容易和更快捷的系统起动 更大的制造灵活性 改进功能 减少故障时间 准确、可靠的诊断数据 可靠的数字传输技术 Users benefit from the use of PROFIBUS in their plants. The customer's advantages are listed on the slide. Further information and detailed examples are given in part 6 of this slide set.

工 程 费 22% 组 装 费 51% The use of PROFIBUS reduces the efforts in wiring up to 40 %. This has been proven by a study of NAMUR (the leading user organization of the chemical industry in Germany) as well as in many successful applications world-wide. User reports (e.g. General Motors, Wacker Chemie ...) clearly confirm these cost reductions. The reports are available in the publications of PROFIBUS International (Web Site, Electronic Product Guide). The cost reductions in hardware are caused by less I/O modules in the PLCs and less wiring cost. Additional savings in the process automation occur due to less power supplies, isolators and barriers. Cost savings in assembly are mainly caused by simple two-wire connections instead of many separate parallel wires. This also leads to cost savings due to reduced maintenance efforts. 23% 硬 件 费 0% Today (4...20mA) PROFIBUS 硬 件 组 装 工 程 来源：: Namur, AK 3.5

10 经认证的产品确保互操作性 Device PROFIBUS 国际已经建立了质量认证系统，包括产品的一致性和互操作性的测试
几百个产品已经通过了认证 在欧洲和美国建有这样的测试实验室 经认证的产品都有一个认证号，它们已在 PROFIBUS 电子产品指南中列出 在测试实验室 进行测试 No OK ? PROFIBUS International has established a qualified certification procedure according to EN Certified products ensure interoperability and conformity. This means that products from different vendors can communicate together without any problems. Each certificate has an individual certification number for reference. The certified products with their certification number are listed in the Electronic Product Guide. They have been tested for their conformity to the PROFIBUS standard. Furthermore the interoperability of the devices from different vendors is part of the test. The tests are performed by accredited test laboratories in Europe or the US. Most of the important users like General Motors require certified products to be used in their plants. The certification is done in 2 steps: First of all the products are tested for their interoperability and conformity to the standard at a test laboratory. Having successfully passed the test procedure they are formally certified by PROFIBUS International. Yes 由PROFIBUS 国际认证

11 PROFIBUS 是领先的开放的现场总线系统
独立的市场研究证实， PROFIBUS 在欧洲是市场的领导者，且在世界范围内有最高的增长率。在１９９７年已安装的PROFIBUS 基本设备超过了 1,500,0001 个，年增长到约 % 。 市场总值 根据 1997 ARC 的市场研究现场总线的世界市场总值大于2 百 万个节点， 50％以上是用在欧洲。 The market for Fieldbus systems has grown very rapidly in the past few years and has now reached a world-wide volume of approx. 2 Mio. nodes per year. The clear winners are open and vendor independent Fieldbus systems while the market share of proprietary networks is rapidly decreasing. In Europe, Fieldbus technology is more popular than in other parts of the world. More than 90% of the installed nodes are used in manufacturing and building automation. After the availibility of real PROFIBUS-PA devices in mid 1997, first digital Fieldbus systems were installed in process automation, and after a period of only three months, more than 15,000 PROFIBUS-PA devices were sold. The market shares of the different Fieldbus systems have been analysed by three different market research companies. Two of them Consultic (Germany) and IMS (United Kingdom), were based on several hundreds of end user interviews. They are focused on market shares during 1996 and a forecast until year Both studies came to the conclusion that PROFIBUS is the clear market leader in Europe. The third study from ARC (USA) is based on vendor interviews only. This study came to the conclusion that INTERBUS-S is the world-market leader. The reasons for the different conclusion are as follows: The ARC study is based on the installed base and not on the actual use (like Consultic and IMS). Due to the fact that Interbus-S has been available on the market for two years longer, the installed base is higher than for PROFIBUS. In contrast to ARC, Consultic and IMS focused on current sales and not on the already installed base. Consultic and IMS clearly state that PROFIBUS is currently the most often used system. ARC is mainly based on vendor interviews with chip manufacturers. ARC did not take into account that a lot of PROFIBUS devices are pure software solutions on standard micro processors. Different market segments have been analysed. 市场份额 根据 1996 Consultic 关于德国和欧洲市场的市场研究2 。PROFIBUS 在欧洲市场中约占 41% 。 1 Status: Q4/1997 2 Details are available for all paid-up members of PROFIBUS International

In this model, every transmission layer handles precisely defined tasks. Layer 1 (physical layer) defines the physical transmission characteristics, Layer 2 (data link layer) defines the bus access protocol. Layer 7 (application layer) defines the application functions. The use of the IEC transmission technology (IEC ) with PROFIBUS = PROFIBUS-PA has been standardized in DIN E part 4 which is currently under vote as amendment 2 to the European standard EN volume 2. The end of the voting period is expected in Q3/1998. (3)-(6) 未用 数据链路层 现场总线数据链路 IEC 接口 (2) 物理层 RS-485 / 光纤 IEC (1) EN PROFIBUS 导则 + 行规

13 三种有效的传输技术: 提供三种不同的物理层选择: PROFIBUS 使用两端有终端的总线拓扑
站 1 ..... 站 n 终端 PROFIBUS 使用两端有终端的总线拓扑 在运行期间，接入和断开一个或几个站不会影响其他站的工作，即使 在本质安全区也如此。 提供三种不同的物理层选择: The transmission technology of PROFIBUS is based on a two-wire twisted pair cable with termination at both ends. The devices are connected in a bus topology. This ensures that all devices can be coupled or un-coupled even in intrinsically safe areas during operation without affecting other devices. This is a very important benefit of PROFIBUS in comparison with other fieldbus systems. 3 different physical layer options are permitted: RS 485 which is used at PROFIBUS-DP and PROFIBUS-FMS. It uses a simple shielded twisted pair cable and can operate on baud-rates up to 12MBit. For PROFIBUS-PA, the IEC transmission technology is used which offers intrinsic safety and powering of the devices over the bus. (Further details see next slide) Fibre optic components are available for use with PROFIBUS. This enables the application of PROFIBUS even in areas with high requirements on electromagnetic compatibility or at very long distances. RS 485: 用于 DP 和 FMS IEC : 用于 PA 光纤: 用于 DP 和 FMS

14 PROFIBUS 协议 PROFIBUS 总线访问协议（第二层）对三种PROFIBUS 版本 (FMS/DP/PA)均相同
因为 FMS/DP 使用相同的物理介质 (RS-485/FO) ，因此它们 能组合在同一根电缆上。 主设备间的逻辑令牌环 主动站、主设备 PLC PC PLC This slide shows the PROFIBUS bus access mechanism. PROFIBUS distinguishes between active stations like PLCs or PCs - they are called Master devices - and passive stations like sensors or actuators - they are called Slave devices. A logical token ring is established by the bus access protocol between the intelligent stations. The right to access the bus is passed between the stations by means of the token. The token is a special telegram which is transmitted over the bus. When a master station owns the token, it has the right to access the bus and to communicate with all other active or passive stations. The overall Token Rotation Time is user defined during configuration. Each station calculates the individual Token Hold Time and ensures that the overall Token Rotation Time is not expired. This guarantees fair bus access for all stations. Simple devices like sensors and actuators need not implement the logical token passing protocol. The advantage is that the protocol is very simple for passive stations which can be realized cost-efficiently by single-chip ASIC technology. All PROFIBUS variations use the same bus access protocol.

This means that one master station, for example a PLC, is connected by PROFIBUS-DP with the distributed peripherals like inputs and outputs or sensors and actuators. PROFIBUS-DP replaces the parallel wiring between the PLC and the peripherals. This reduces costs up to 40%. A PROFIBUS-DP mono-master system consists of 1 to 125 Slaves; i.e one Master class 1 - this is the PLC - and up to 125 Slaves. The mono-master systems reach the shortest bus-cycle time and are able to transmit 1 kByte of input and output data in less than 2 ms. It is also permitted to build Multi-Master Systems with PROFIBUS-DP. Details are described later. 从站 从站 从站 从站

17 PA = Process Automation
PROFIBUS-PA 的特点 PA = Process Automation 基于扩展的 PROFIBUS-DP 协议和 IEC 传输技术 适用于代替现今的 mA 技术 仅用一根双绞线进行数据通信和供电 通过串行总线联接仪器仪表与控制系统 适用于本质安全的 EEx 应用区域 可靠的串行数字传输 通过一根双绞电缆进行控制、调节和监视 对所有设备只需一个工程工具 由于 PROFIBUS-PA 行规，保证了互操作性和互换性 仪器仪表的维护和诊断信息 PROFIBUS-PA is the PROFIBUS solution dedicated to the process industry. It is suitable to replace today's mA technology and it offers functional improvements and a reliable digital transmission technology. Control, regulation and monitoring can be done via a simple twisted pair cable. It is permitted e.g. to transmit the measured value together with the related status of the field device over the bus. PROFIBUS-PA can be used in intrinsic safe areas and offers the possibility to power the field devices over the bus. The PROFIBUS-PA profile ensures full interoperability of devices from different vendors. It is based on the internationally accepted function block technology.

18 + 带有 PROFIBUS-PA 的典型系统配置 H2 H1 I 区域控制器 (PLC) PROFIBUS-DP 工程或 HMI 工具
RS 485 up to 12 MBit/s PROFIBUS-DP + I IEC with kBit/s Usually, the DCS controller as well as the engineering tool are located in the non-intrinsic safe area and therefore they are connected to the high speed (H2) PROFIBUS-DP network. The barrier between the intrinsic safe area (H1) and the non-intrinsic safe area (H2) is realized by a segment coupler or link which optionally provides the power for the instruments. The intrinsic safe field devices may be powered over the bus or - if they have higher requirements for powering - they can be externally powered using Ex d protection. From the view of the DCS controller there is no difference if a field device is located in the intrinsic safe area or the non-intrinsic safe area because in both areas the same protocol is used. PROFIBUS is the only Fieldbus system which has a complete H1 and H2 technology available and that provides such an elegant transition between the two application areas. PROFIBUS-PA H1 段合器／链接器 变送器

21 开放的组态允许即插即用 系统组态 PLC PLC 电子设备数据单 (GSD-files) PROFIBUS PROFIBUS 组态工具
PROFIBUS does not only describe the communication of the devices, the PROFIBUS specification also includes a complete description for open and vendor independent configuration. The configuration tools use electronic data sheets of the devices. These electronic data sheets are designated as device data base files or GSD files. The vendors of the devices describe the functionality of their devices by means of a GSD file. The format of the GSD file is clearly defined by the PROFIBUS standard. The configuration tool reads the GSD files into its internal data base and takes all characteristics of the individual devices into account. The advantage is that the configuration is very simple and can be done by a vendor-independent configuration tool. So PROFIBUS-DP really offers plug-and-play solutions and reduces the engineering costs. GSD files are simular to Windows INF files for printer or modem definitions. 电子设备数据单 (GSD-files) PROFIBUS
