Difficult, variable security environment – Best practices don’t exist Incomplete and conflicting standards Conflicting frequencies and protocols Haphazard growth & inconsistent quality of point solutions Not industrial quality Poor migration path for investment preservation Inconsistent support within IT organizations Cost of operation uncertainties Network management challenges
More measurement at lower cost Greater availability of real-time data integration Strategic measurements provide process improvements Eliminating wires means significant cost savings More capability for limited budgets More mobile workforce Connecting human, rolling, and remote assets with field applications New applications drive bottom line improvements Many maturing wireless point solutions offer key benefits for plant optimization & enterprise asset management New measurements address mandated requirements Personnel safety & plant security Wireless is key enabler for enterprise-wide solutions
There are many different organizations working on issues of co-existence and interoperability. This will take a long time to sort out. WINA and SP100 are leading the effort to make sense of all of this. Invensys is in a leadership position with both WINA and SP100 WINA activities include: Monthly Educative Webinars Major support and development for SP100 Writing the book on Wireless Best Practices (Winter ’06) 1451.5, 802.15.4, 802.11, 802.16 Interoperability Demonstration – ISA ‘05 Interoperability Test Bed – Ongoing User interface into numerous standards organizations SP100 activites include: The ISA-SP100 Committee will establish standards, recommended practices, technical reports, and related information that will define procedures for implementing wireless systems in the automation and control environment Guidance is directed towards those responsible for the complete life cycle including the designing, implementing, on-going maintenance, scalability or managing manufacturing and control systems, and shall apply to users, system integrators, practitioners, and control systems manufacturers and vendors. The Committee’s focus is to improve the confidence, integrity, and availability of components or systems used for manufacturing or control, and provide criteria for procuring and implementing wireless technology in the control system environment. Compliance with the Committee’s guidance will improve [wireless] manufacturing and control system deployment, and will help identify vulnerabilities and address them, thereby reducing the risk of compromising or causing manufacturing control systems degradation or failure.
In Wide Area Networks, the information is chopped into packets (a method of multiplexing). What is most common topology in industry? Bus for Ethernet, Modbus, etc. Star for RS232. Ring for token ring. Which one is practical only for wireless networks? - Mesh since connections are virtually free! There are no absolutes but architectures have interesting histories.
There are many different types of Wireless technology, each satisfying a different type of application. WiFi is probably the most well known type of Wireless technology, and satisfies the criteria for low range, good bandwidth computer applications, such as remote workstations, laptops, PDAs etc. WiFi is based on a NLOS (Non Line Of Sight) centralized Access Point model, that allows wider coverage through cells of APs. Typically range of a signle AP is in the hundreds of meters. WiMax lends itself to a different part of the network hierarchy and allows us to replace an area that has always historically been wired, the infrastructure backbone. A WiMax backbone gives you a long range, high bandwidth connection which can provide connectivity directly or via other wireless technologies through access points and gateways. WiMax can be installed as LOS (Line Of Sight) or NLOS, depending on the range requirements. Distances approaching 30-50KM are currently possible in LOS applications, whilst NLOS give ranges around 5-10KM. Wireless Sensor Networks are revolutionizing the ways in which wireless instruments and transmitters connect to control systems. Instrumentation has always been physically wired, which have led to expensive installations, and often lack of accessibility has restricted placement. WSN distinguishing feature is that they are designed to operate on very low power consumption with battery life in the 3-5 year range. There are several topologies in use depending on the vendor. Radio Frequency Identification is allowing plants to keep track of valuable inventory, parts and personnel. The exact location of an item can be tracked anywhere within the wireless infrastructure.
Before we discuss Microsoft’s offering for the Manufacturing Industry I would like to review with you a typical IT infrastructure of a Manufacturing company. In the 1970’s, the central theme of information systems was hardware, and the result was almost always a hierarchical system centered on the company mainframe for commercial systems and perhaps manufacturing planning, with separate design, engineering and shop floor solutions. By the 1980’s, information systems for manufacturing had become more focused on applications, with numerous applications economically available for tasks ranging from process control and manufacturing planning to product design. PC networks and UNIX based systems appeared in large numbers. ‘Open Systems’ promised easy integration and access to data as well as vendor independence. If a new application needed a new Operating System, then, so ,long as enough ‘Open System’ standards were supported, the new Operating System could fit into the enterprise’s Information Technology (IT) architecture. The result of this is a variety of different systems on different hardware platforms difficult to interface and sometimes impossible to integrate. Each Operating System needs its own specialist. Even dialects of UNIX each need their own specialist Another common factor is that these systems are not only complex and expensive to support they are also very difficult to change. Meeting the requirements (in terms of IT infrastructure) for BPR projects has become a nightmare for many IT departments adding additional cost and complexity.
Security is addressed at all levels of the system. There are data, configuration, access, device, and systems management security considerations. This slide describes some of the highlights around access and data management security.
OSHA would like automatic notification of a safety shower being activated to go straight to Emergency Services so EMT’s can be deployed immediately to the correct location. In this plant there are over 1000 showers. Wiring costs would be enormous Wireless sensors on a mesh network coming back into the system are the answer.
The first step is to develop a Site Assessment Study – jointly produced by a team from Invensys, Apprion, and the end user – consisting of members representing: Process Operations Process Engineering Maintenance Safety Security IT Together we can define a strategy, plan and roadmap that provides the correct systems architecture for the site and the applications being requested.
