s Preliminary SIMATIC WinCC Thin-Client Solutions with the WinCC/Web Navigator Overview Operating and Monitoring Across the Worldwide Web The WinCC/Web Navigator option package represents the arrival of process visualization via the Internet in industrial applications. WinCC/Web Navigator allows you to visualize and operate your plant via the Internet or your company s Intranet or LAN. For a configuration like this you need a Web Navigator Server on which the SIMATIC WinCC V5 software is installed as a single-user or server version and a Web Navigator Client. The Web Navigator Client is a thin client that makes possible operating and monitoring of an ongoing WinCC project by means of an Internet browser with ActiveX support without needing the WinCC basic system on the client computer. Thin² Client: Merging Web and Terminal Server Technologies Siemens A&D is now also introducing WinCC for client-server applications in which you can use simply equipped Window PCs, rugged Windows CEbased terminals or mobile handheld devices as operating stations. Siemens is the first company on the market to use an innovative thin²-client strategy that combines the advantages of the Web and terminal server technologies. This strategy is based on the terminal service of Windows 2000, which is supported by Version 1.1 of the WinCC/ Web Navigator. This makes possible thin-client solutions on different platforms, including clients at the machine based on the Windows CE 3.0 real-timecapable operating system (e.g. the rugged industrial SIMATIC MP370 with touchscreen), mobile clients such as Personal Digital Assistants (PDAs) or industrial Web Pads like MOBIC T8 running Windows CE, standard PCs running a Window PC operating system (e.g. Windows 3.1 or MS Windows 9x) as well as Linux and Unix clients (using third-party products). This means that users can be particularly flexible when choosing their hardware, since in a physically distributed WinCC multi-user solution they can use specialized equipment on the one hand or even integrate computers as clients that have relatively low specifications or run relatively old operating system versions.
Your Benefits at-a-glance Distributed multi-user solutions with any type of target clients Free choice of clients: rugged, mobile extremely low-priced Server in a safe environment Centralized software administration High performance also in case of undersized client hardware Scalable, highly available, secure Intelligent session management Mixed operation of real web clients and terminal sessions Easily expandable if necessary Technical Implementation WinCC, Web Navigator Server and Client are installed on a Windows 2000 Server computer on which the terminal service was activated. By contrast with typical Web Navigator installations, the thin clients are generally located on the same LAN as the server. However, accesses are also permissible via WAN, RAS and even the intranet/internet. You can integrate mobile equipment using different media, like mobile radio connections (e.g. HSCSD) or Wireless LAN. The network connection between the server and the clients is by means of the TCP/IP protocol. When you use MetaFrame, the system supports IPX/ SPX and NetBUIE as communications protocols in addition to TCP/IP. The RDP protocol (Remote Desktop Protocol) is used as the transport protocol to transfer the user interface and console activity between the client and the server. This protocol complies with the T.120 standard and is also used by Microsoft s NetMeeting. Overview of Thin-Client Technologies Terminal-Service in Windows 2000 The principle of thin-client/-server computing is based on the physical separation of data, applications and screen output. The terminal services of Windows 2000 allow undersized PCs or specialized thinclients to run applications such as the Internet Explorer or typical office applications - in the main memory of a central Windows 2000 terminal server instead of their own. In this case, client PCs are turned into terminals that only serve for the purpose of entering data (via keyboard or mouse) and of sending this data to a terminal server. The terminal server carries out the actual processing (for instance, the loading of When you operate WinCC/Web Navigator under Windows 2000 Terminal Services, you can connect up to 25 thin clients. If you want to connect more clients, it is advisable to separate the WinCC/Web Navigator server and the terminal server. In this connection, it is then possible to supply in-parallel several terminal servers from one WinCC/Web Navigator server. The process link to the PLC and other data a Web document or the updating of process pictures) and returns the resulting screen output to the client PC, which then displays it on its monitor. Such client sessions can be transferred from one operating station to the next. Compared to traditional client-server architectures, the yearly administration and maintenance costs of thinclients is 3 to 5 times less. HMI/ SCADA systems often only carry out one or a few applications on the client workstations. In this respect, they are also ideally suited for the use of the terminal server techno-logy. sources is established using appropriate WinCC process links.

Thin-Client Technology in Detail Any type of target clients WinCC/Web Navigator under Windows 2000 Terminal Services allows operation and monitoring of unchanged WinCC process pictures including all the dynamics on virtually any target systems you like. These include primarily all Windows operating systems (Windows 3.1 and above, Windows CE, Embedded NT etc.) as well as other operating systems like Linux, UNIX, MacOS and others. For MacOS, you must use the MetaFrame operating system extension for Windows 2000 by Citrix. Depending on the hardware that you use, there may be limitations on the display, e.g. the resolution, colour palette, etc. Free choice of clients: rugged, mobile extremely low-priced For their part, you can deploy the clients under the most rugged operating conditions (vibrations, high temperatures, hazardous locations), since the clients do not necessarily need a hard drive or a fan. If a client should fail, you can replace it within a very short time. All you need to do is physically connect a new unconfigured thin client to the Network. The ongoing session on the server can be applied without being interrupted. The most suitable client platforms are of course the Siemens system-tested ones (MP370-Thin Client and MOBIC); apart from this, you can use PCs and thin clients made by any manufacturers, which can be function as RDP and ICA clients. You can integrate mobile equipment using different media like mobile radio connections or Wireless LAN. Server in a safe environment One advantage is that the entire application logic executes on a central server and only exchanges screen contents and keyboard and mouse inputs with the connected clients. This makes it possible to separate the server and clients, which mirrors the natural separation of tasks in many companies. The server is run by the IT department, which administers and archives it and keeps it highly available. Centralized software administration Since the entire application logic is concentrated on the central terminal server, you only need to install once the operating system and the WinCC software. This means that whenever you need to make changes on the server or in the user project, you only need to do it once with all the clients being updated automatically. High performance in the case of lowspecification client hardware too When carrying out processing on the thin clients, the same performance is available as on conventional clients. This is guaranteed by the adequate network bandwidth (20 kbps per client) and the server s generous hardware configuration. Since the complete WinCC is not executed several times but rather only the Web Navigator Client, which is itself a thin client, the advantages increase even further. This makes Thin²-Design is just one of the features that make the product unique on the market. Scalable, highly available, secure Once several clients are operating on one server, handling failures becomes a critical point in all the applications. This is particularly significant, since the server gathers all the functions including the client logic on the same hardware. Precautions against this cannot just be taken by using hardware redundancy (RAID systems). There is also the option of grouping several terminal servers in clusters or server farms. This spreads the server load to several machines. On the one hand, this is for dynamic load distribution with a large number of active clients, and on the other for carrying out repairs and maintenance during ongoing operation. Apart from this, WinCC s integrated redundancy function (WinCC/Redundancy option) offers automatic archive matching that makes possible consistent data storage, e.g. for quality assurance systems, even if a subsystem fails. In addition to offering consulting services at the design stage of corresponding server systems, Siemens can also configure and supply Fujitsu Siemens server systems. The use of thin clients offers the same security mechanisms that are you are familiar with from the Web Navigator. These include authentication of users using a login and password, secure communications connections and access only to resources that are activated for specific users. In this connection, the system uses both operating system and WinCC mechanisms. Mixed operation of real web clients and terminal sessions Users can start operator activities at an operator terminal and arrange a userspecific window layout. If you have to work at another operator station, e.g. to view a process directly, you can apply the session directly there. If process situations occur that inexperience users are not able to cope with, a supervisor can mirror this operator session and carry out operator activities together with the plant operator. Mirroring is also possible across the intranet/internet. Using the solution presented here, you can not only solve conventional system configurations in a different way, it also enables slow migration, since you can mix both real clients and terminal clients on one network (hybrid operation of clients/thin clients). Easily expandable if necessary The terminal application can grow with your requirements. You can simply connect more clients to the network and they function straight away. The hardware configuration of the server must of course grow at the same rate as the number of clients increases. If necessary, you can group several terminal servers into a virtual network to better distribute the communications load.
Complete Range of Products and Services from one Hand With its many years of experience in the field of industrial Operator Panels and its innovation leadership with CEbased devices ( Multifunctional Platform ), Siemens A&D was able to be the first provider of complete thinclient solutions. In a first step, the new 12" touchscreen device, the MP370 Thin-Client and the mobile Industrial Web Pad MOBIC were optimized and system-tested for the operation with WinCC. This means that customers not only receive the solution from a single source, but also a guarantee that these components are ideally matched to each other. However, a thin-client solution can only be as good as the server hardware employed, since this is where the actual processing is carried out. For this reason, the server systems that are SIMATIC MP370 Thin Client The multifunctional platform combines the ruggedness of dedicated hardware solutions with the flexibility of the PC world. The products in this category the Multi Panels (MP) are based on Microsoft Windows CE and like Operator Panels before them they can be used for on-site machine control and monitoring. In addition to visualization, these devices can also perform other automation tasks, for example in the PLC area. Windows CE creates the basics for the application in harsh industrial environments. Since they do not operate with hard drives or fans, the SIMATIC Multi Panels can also be used for visualizations in areas, where vibration and dust would limit the application of a PC. Short startup times make the Multi Panels ready for work quickly. In the thin-client version, the MP370 Touchscreen comes equipped with terminal server client application. In addition to performing on-site automation tasks, the device also functions as a thin client in conjunction with the Web Navigator, which is easily implemented with its integrated Ethernet connection. Mobile Industrial Communicator MOBIC T8 Thin Client The Mobile Industrial Communicator is a mobile, industrial Web Pad for the local or world-wide access to the Intranet and Internet. The MOBIC T8 can be integrated into any IT network infrastructure via wireless LAN or via Ethernet at 10/100 Mbps. It can be used in production and service areas (for displaying production and quality data). Service technicians can be notified by the control room, edit a job request or acknowledge operations. As a thin client on the Web Navigator, they have access to current process data (errors, process values, production data). based on proven Fujitsu Siemens products are also part of the complete thin-client solution. These systems must be scaled according to the respective application and be designed with regard to the availability requirements. Siemens offers this service as well as consultation and configuration within the framework of a complete solution. This means that customers will always find a customized range of products and services from components right up to the on-site installation of the complete solution.
