3Network PositioningEtherNet/IP Past/Present: Link to MES/ERP, Used for Programming, Controller to HMI, Some Controller to Controller,Present/Future: Present functionality, Controller to HMI, Controller to Controller Communications, and I/O. Backbone for lower-level networks.ControlNet Past/Present: Backbone, I/O, Controller to Controller, Controller to HMI,Programming, Information MessagingPresent/Future: High-performance, robust, secure network primarily for I/Oand interlocking. Backbone for lower-level networks.DeviceNet Past/Present: Simple distributed I/O devices, HMI, and 3rd Party devicessupporting configuration and diagnosticsPresent/Future: Present functionality and make it easier to user whileproviding lower node / installation / maintenance cost
4Strengths of DeviceNet Lower Acquisition and Installation CostReduction in plant wiring (eliminates hardwiring of I/O)Lower installation, start-up, and maintenance timesNetwork AttributesData flow is governed by the Producer/Consumer modelAbility to link smart factory floor devices togetherAbility to bridge to higher level networksSuperior device level diagnosticsDevice Plug and Play capabilities - add or remove nodes on the flyOptimized to handle small amounts of data8 bytes per messagesupports message fragmentation for larger data sizes)Media OptionsPassive bus media: nodes can enter and leave without affecting the networkSealed (IP67) and unsealed (IP65) mediaLow cost flat media
5Strengths of ControlNet High Speed DeterminismDeterministic data transfer - know when the data will arrive (Scheduled services)Repeatable data transfer - transmission times are consistent as devices enter and leave the networkRedundancyRedundant media is availableProcessor redundancyPLC-5 Hot BackupControlLogix Processor RedundancyIndustrial Hardened Physical MediaHigh noise immunity (coaxial and fiber optic cabling)Intrinsically-safe media and products (Flex Ex, fiber optic repeaters)Sealed (IP67) media currently being developedPassive MediaNodes can enter and leave without affecting the networkTrunkline topology
6Strengths of EtherNet/IP Highly efficient data transferIncreased baud rates (10Mb, 100Mb), use of switches (instead of hubs), full duplex data transmission to minimize effect of message collisions, and isolation from the office Ethernet networkUse of commercial off the shelf products and technologyCommon set of installation and support toolsWell established network standard, acceptance rate should be favorableCan take advantage of web browsing services in the productsMedia OptionsActive bus media: supports star network topologiesHigh noise immunity (fiber optic cabling)Extend bus length with multiple switches (copper and fiber)Sealed (IP67) media - emerging technology (Consortia lead by RA)
7General Network Selection Guidelines EtherNet/IP – more complex devices and larger I/O count blocks and racks where a combination of medium to high performance I/O and a large amount of messaging is requiredControlNet – more complex devices and larger I/O count blocks and racks where highly deterministic I/O performance with some messaging is requiredDeviceNet – simple distributed devices and small I/O count blocks installed along side electrical/mechanical equipmentThere is no absolute answer!

11OPC DXIndustry-standard set of interfaces that provides interoperable data exchange via server-to-server communications across Ethernet networksExtension of the existing data access (OPC DA) specificationEnables server-to-server data exchange during run-time.Defines a set of interfaces that can be used to remotely configure and manage the connections maintained by each OPC DX serverServer connections are remotely configuredCan be monitored for performance and diagnosticsIn addition to AND independent of any real-time application protocol - if any - that may be supported by the Ethernet TCP/IP network(s).

17Wireless Networking Strategy Offer Wireless LAN solutions with today’s existing RA, Encompass Partner, and other COTS productsGMS can/will assist on design and installation (site surveys, installation, etc.) of Wireless LAN solutionsRA to continue to pursue the wireless portable HMI marketKeep an eye on the wireless technologies and standardsWireless technology is still incredibly volatile. Stay abreast of the direction that wireless technology is heading.As the technologies mature and customer requirements expand, make sure that RA does not get closed out of a market due to lack of participation.
18Wireless Recommendations from ACIG 1) Offer Wireless LAN solutions with today’s existing RA and Encompass Partner products.Include complementary wireless Encompass Partner products to broaden wireless solution offering.Upon completing the wireless ethernet testing that Mike Pelley and Thomas Sugimoto are doing today in IFT, RA should be comfortable offering COTS wireless ethernet products in conjunction with RA and Encompass partner products as a wireless solution to a customer.Our Encompas partners have been offering various wireless solutions for years. We can couple those with the results of our wireless ethernet testing and offer a solution that can address a broader range of applications.
19Wireless Recommendations from ACIG 2) Use GMS as installation expert for Wireless LAN solutions.Incorporate WLAN expertise as part of Network Services within GMS organization.Site surveys done at customer facility.Recommends wireless RA and Encompass Partners products to solve customer problems.Provide installation and routine maintenance services.HMIMaintenance PCOnce the wireless ethernet testingn results are known, it would make sense for SSG to become the wireless experts. Offer this service as part of the Network Services group headed up by Darin Fleming.
20Wireless Recommendations from ACIG 3) Pursue wireless portable HMI market.IPB is shipping MobileView products todayHMIMaintenance PCTo fill the customer need of data collection, device configuration, and programming, IPB will be offering a line of wireless products called MobileView.The first series of products are scheduled to ship in July 2001.
21Wireless Recommendations from ACIG 3) Keep an eye on wireless technology and wireless standards.Wireless technology is still incredibly volatile. Stay abreast of the direction that wireless technology is heading.Wireless standards are still evolving. Make sure that RA does not get closed out of a market due to lack of participation.Contact Doug McEldowney or Stu Siegel if any issues/questionsRA needs to keep our eye on wireless technology to make sure that we do not get closed out of any markets if a wireless spec takes a new direction or adds additional functionality.If the coexistance problem between BT and b is solved. Then RA needs to re-evaluate our stance on BT.A company called Mobilian (www.mobilian.com) is doing development on a radio that can accommodate both radio types (BT & b).If a gains more steam in the market, then maybe we need to a closer look at that standard.
