    5. 5 | ISA Oct. 2008 | Ira Sharp | Interface | 10/21/2008 Wireless Technologies Different wiring types Sensor (Parallel cable) 4-20mA, 0-20mA, 0-10V, RTD, Thermocouple Actuators (Parallel cable) Digital (On/Off) PLC to PLC (Serial) RS-232, 422, 485, Ethernet Different wiring types for different applications.

    6. 6 | ISA Oct. 2008 | Ira Sharp | Interface | 10/21/2008 Wireless Technologies Different wireless types Sensors & Actuators (Similar to Parallel cable) I/O to I/O proprietary solutions (Wire in Wire Out) PLC to PLC (Similar to Serial cable) Serial proprietary solutions, Bluetooth, 802.11, UHF, etc. ISA100 There is no One Size Fits All wireless solution. There are many different solutions for different applications.

    7. 7 | ISA Oct. 2008 | Ira Sharp | Interface | 10/21/2008 Selecting the correct technology There is no One Size Fits All

    8. 8 | ISA Oct. 2008 | Ira Sharp | Interface | 10/21/2008 Which is faster (better)?

    9. 9 | ISA Oct. 2008 | Ira Sharp | Interface | 10/21/2008 Which is faster (better)?

    10. 10 | ISA Oct. 2008 | Ira Sharp | Interface | 10/21/2008 Which is faster (better)?

    11. 11 | ISA Oct. 2008 | Ira Sharp | Interface | 10/21/2008 Selecting the correct technology There is no One Size Fits All Why the difference? Energy Per Bit

    12. 12 | ISA Oct. 2008 | Ira Sharp | Interface | 10/21/2008 RF Technology Spread Spectrum Use only a portion of available bandwidth at any given time Different modulations offer different throughputs

    13. 13 | ISA Oct. 2008 | Ira Sharp | Interface | 10/21/2008

    14. 14 | ISA Oct. 2008 | Ira Sharp | Interface | 10/21/2008

    15. 15 | ISA Oct. 2008 | Ira Sharp | Interface | 10/21/2008 Selecting the correct technology Different Technologies (Today)

    16. 16 | ISA Oct. 2008 | Ira Sharp | Interface | 10/21/2008 Selecting the correct technology Different Technologies (Tomorrow)

    17. 17 | ISA Oct. 2008 | Ira Sharp | Interface | 10/21/2008 ISA100 What is it? Establish standards and related information that will define procedures for implementing wireless systems in the automation and control environment with a focus on the field level.

    18. 18 | ISA Oct. 2008 | Ira Sharp | Interface | 10/21/2008 ISA100.11a Update ISA100.11a Draft 2 (10/14) Failed to pass (63% Supported) 2-3 months expected for Draft 3 ISA100.11a Key Components Low Energy Wireless Infrastructure Robustness Coexistence Interoperability

    19. 19 | ISA Oct. 2008 | Ira Sharp | Interface | 10/21/2008

    20. 20 | ISA Oct. 2008 | Ira Sharp | Interface | 10/21/2008 ISA100 and WirelessHART (WSN)

    21. 21 | ISA Oct. 2008 | Ira Sharp | Interface | 10/21/2008 WSN and Gateways

    22. 22 | ISA Oct. 2008 | Ira Sharp | Interface | 10/21/2008 Select the correct technology for the application

    23. 23 | ISA Oct. 2008 | Ira Sharp | Interface | 10/21/2008 Application Wireless I/O (Long Distance) Application An analog signal needs to be collected from a remote pumping station. Which reports the level of the water tank. Problem Laying cable and conduit is simply to costly. The distance was 5200’ and cable must be run under two roads.

    24. 24 | ISA Oct. 2008 | Ira Sharp | Interface | 10/21/2008 Application Long distance communications at 5200 feet Wire in/ Wire out need

    25. 25 | ISA Oct. 2008 | Ira Sharp | Interface | 10/21/2008 Application Wireless I/O (Short Distance) Application Collect data from various sensors located on machinery that will be used for predictive maintenance. Problem There is no easy way to wire sensors located on the machinery back to a PLC to be monitored. There are many obstructions and this is a high noise environment that does not lend well to parallel wiring.

    26. 26 | ISA Oct. 2008 | Ira Sharp | Interface | 10/21/2008 Application Proprietary Wireless Solution Make a wired sensor, wireless Wire in/ Wire out technology can make this happen today Radios must be wired for power or solar powered

    27. 27 | ISA Oct. 2008 | Ira Sharp | Interface | 10/21/2008 Application WSN Solution Wired sensors can still be made wireless The WSN radios will “Mesh” in small clusters WSN radios are battery powered. No hard wiring needed. WSN is made for short distances a Long Hall radio will be needed

    28. 28 | ISA Oct. 2008 | Ira Sharp | Interface | 10/21/2008 Application Serial Application Tank levels must be monitored from a verity of tanks. This information must be collected by a PLC. Problem The tanks are spread over a vary large area and it is simply to costly to run cable and conduit to each location.

    29. 29 | ISA Oct. 2008 | Ira Sharp | Interface | 10/21/2008 Application I/O is collected at each tank, reported to the radio, Then sent to the master PLC. This can be more reliable then wired connections as there is no worry that a trenched cable will become damaged over time.

    30. 30 | ISA Oct. 2008 | Ira Sharp | Interface | 10/21/2008 Application Ethernet Application An existing security system has become antiquated. This system needs updated and new cameras must be installed. Problem The locations where new cameras must be installed are to difficult or expensive to wire for connection.

    31. 31 | ISA Oct. 2008 | Ira Sharp | Interface | 10/21/2008 Application Ethernet Cameras or Analog cameras processed with a video server can be connected to the Ethernet Radios The video will be streamed to the master radio and can be archived or viewed at the master station

    32. 32 | ISA Oct. 2008 | Ira Sharp | Interface | 10/21/2008 Application Serial and IO Application The contents of trucks transporting various materials needs to be monitored for temperature, quantity, and location for quality purposes. Problem The trucks transport these materials around the United States and Canada. Currently a PLC is used to monitor temperature and quantity of the material although this data can only be downloaded when the truck is parked at its destination.

    33. 33 | ISA Oct. 2008 | Ira Sharp | Interface | 10/21/2008 Application GSM/GPRS Data-loggers or PLCs are used to collect and archive data GSM/GPRS modem will provide international access to the cellular network. This allows for monitoring of the truck and its contents.

    34. 34 | ISA Oct. 2008 | Ira Sharp | Interface | 10/21/2008 Applications Different applications have different requirements Things to consider How far does the signal need to go? Feet, Miles, Country, World What is the density of the nodes? Remote, Dense What update times are required? Days, Hours, Minuets, Seconds, Milliseconds What type of data will be communicated? I/O, Serial, Kbps, Mbps, Gbps Is power available? Hardwired, Battery, Solar

    35. 35 | ISA Oct. 2008 | Ira Sharp | Interface | 10/21/2008 Selecting the correct technology There is no One Size Fits All
