Wireless Introduction and RA Strategy Overview
Agenda
• What problems are we trying to solve?• Application Matrix• Technologies• Strategy Overview• Recommendations• Chief Considerations• Readiness Assessment• Encompass Partners
What problems are we trying to solve?
• Eliminating Wires and Cables– Increase Reliability
• Replace Festoon cables (Moving machinery)– Reduce Installation Cost
• Wireless I/O, Wireless Sensor and mesh networks• Reach great distances (SCADA)• Cross electrical and physical barriers
• Enabling Portability and Mobility– Mobile HMI (People)– AGVs (Equipment)
• Tracking Assets– RFID (Coarse)– RTLS (Fine)
• Combinations– AGVs w/Active RFIDs, etc.

Wireless Technology Evolution
• Just as Ethernet has evolved from an office network, to a network that could be applied in some industrial applications, to a network suitable for real-time plant floor control today…
Evolution of “wired” Ethernet for control applications
Past Today Future
10M 100M 1000M
Half-duplex Full-duplex
Hubs Switches Enhanced Features
…so too will wireless technology evolve for easily deployable, real-time, plant floor control applications.
Wireless for “real-time” applications is where Ethernet for control applications were 3-
5 years ago. Commercial needs (i.e. Voice over IP) will help drive solutions that can be leveraged by EtherNet/IP.
RA Wireless Strategy Summary
• RA offers wireless solutions by leveraging available COTS and Encompass Partner products and solutions– EtherNet/IP uses standard 802.3 Ethernet and is therefore compatible with standard
wireless infrastructure products and solutions• For wireless LAN applications, promote 802.11 wireless standards
– RA Encompass Partners offer standard and non-standard wireless products and solutions for a broad range of applications
• Services– Offered by Encompass Partners to complement their solutions
• Continue to track wireless technologies and standards– Wireless technology standards continue to evolve– As wireless technologies and standards mature, work closely with customers to identify
requirements and deliver best-in-class solutions• Wireless LAN applications• Wireless I/O applications• Sensor-based applications• Other application-specific products
Recommendations
• Understand where wireless is appropriate– No fully wireless factory (still need power cables) - still many excellent applications– Mostly for information, limited control usage possible today – more in the future ???
• Understand where wireless is beneficial– More efficient workflow
• Access to multiple information sources without travel or second party involvement• Information entry for paperwork reduction, auditing, and alert
– Legacy retrofit for automatic information gathering• Maintenance, temporary or experimental deployment
– Cable replacement for festoon or great distance• Determine IT involvement
– Security, LAN re-use, maintenance • Perform a site survey• Get a partner with industrial wireless packaging and installation
experience
Chief Considerations
• Wireless device power– Battery power– Power scavenging : Vibration, Light– RF power
• Environment compatibility– Indoor/outdoor, temperature,
contaminants, wash-down • Achieving proper coverage
– Antennas / placement, reliable bandwidth, minimize radios, channel usage (3D), redundancy
• Cost– Installation, power, communication,
enclosures
• Data Reliability– Slow updates allow retries– Ensure safe state on link loss
• Transmission reliability– Noise and interference immunity
• Existing wireless, legacy radios, microwave ovens, cordless phones, emerging radios, process, fusion lighting
– Alternative routing paths• Quality of service
– Guaranteed bandwidth– Deterministic transmission delay
• Security– User authentication, Access control, RF
Signal leaks, good antennas can pick up signals from far away
…control of the application or process• Where variance of a few 100ms between packets is unlikely to be within acceptable
limits.• Solutions available, proceed with caution• Recommend consultation
…data collection• Where variance of a few 100ms between packets
is likely to be within acceptable limits.• Solutions readily available, proceed with caution
If the wireless application is for…
…system / device configuration• Where variance of a few 100ms between
packets is not visible to the user.• Solutions readily available
