3. Network Positioning
EtherNet/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 Messaging
Present/Future: High-performance, robust, secure network primarily for I/O
and interlocking. Backbone for lower-level networks.
DeviceNet Past/Present: Simple distributed I/O devices, HMI, and 3rd Party devices
supporting configuration and diagnostics
Present/Future: Present functionality and make it easier to user while
providing lower node / installation / maintenance cost

4. Strengths of DeviceNet
Lower Acquisition and Installation Cost
Reduction in plant wiring (eliminates hardwiring of I/O)
Lower installation, start-up, and maintenance times
Network Attributes
Data flow is governed by the Producer/Consumer model
Ability to link smart factory floor devices together
Ability to bridge to higher level networks
Superior device level diagnostics
Device Plug and Play capabilities - add or remove nodes on the fly
Optimized to handle small amounts of data
8 bytes per message
supports message fragmentation for larger data sizes)
Media Options
Passive bus media: nodes can enter and leave without affecting the network
Sealed (IP67) and unsealed (IP65) media
Low cost flat media

5. Strengths of ControlNet
High Speed Determinism
Deterministic data transfer - know when the data will arrive (Scheduled services)
Repeatable data transfer - transmission times are consistent as devices enter and leave the network
Redundancy
Redundant media is available
Processor redundancy
PLC-5 Hot Backup
ControlLogix Processor Redundancy
Industrial Hardened Physical Media
High noise immunity (coaxial and fiber optic cabling)
Intrinsically-safe media and products (Flex Ex, fiber optic repeaters)
Sealed (IP67) media currently being developed
Passive Media
Nodes can enter and leave without affecting the network
Trunkline topology

6. Strengths of EtherNet/IP
Highly efficient data transfer
Increased 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 network
Use of commercial off the shelf products and technology
Common set of installation and support tools
Well established network standard, acceptance rate should be favorable
Can take advantage of web browsing services in the products
Media Options
Active bus media: supports star network topologies
High noise immunity (fiber optic cabling)
Extend bus length with multiple switches (copper and fiber)
Sealed (IP67) media - emerging technology (Consortia lead by RA)

7. General 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 required
ControlNet – more complex devices and larger I/O count blocks and racks where highly deterministic I/O performance with some messaging is required
DeviceNet – simple distributed devices and small I/O count blocks installed along side electrical/mechanical equipment
There is no absolute answer!

11. OPC DX
Industry-standard set of interfaces that provides interoperable data exchange via server-to-server communications across Ethernet networks
Extension of the existing data access (OPC DA) specification
Enables 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 server
Server connections are remotely configured
Can be monitored for performance and diagnostics
In addition to AND independent of any real-time application protocol - if any - that may be supported by the Ethernet TCP/IP network(s).

17. Wireless Networking Strategy
Offer Wireless LAN solutions with today’s existing RA, Encompass Partner, and other COTS products
GMS can/will assist on design and installation (site surveys, installation, etc.) of Wireless LAN solutions
RA to continue to pursue the wireless portable HMI market
Keep an eye on the wireless technologies and standards
Wireless 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.

18. Wireless 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.

19. Wireless 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.
HMI
Maintenance PC
Once 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.

20. Wireless Recommendations from ACIG
3) Pursue wireless portable HMI market.
IPB is shipping MobileView products today
HMI
Maintenance PC
To 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.

21. Wireless 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/questions
RA 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 ( 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.
