    New ISA100 Wireless capabilities demonstrated at recent trade shows

    ISA100 Wireless™ product demonstrations at the 2013 Hannover Messe Fair and the ISA Calgary show were met with record user interest and highlighted the ISA100 WCI supplier innovations that are evolving the industrial process automation industry.   Demonstrations showcased peer-to-peer control, support for three different legacy protocols in a single ISA100 Wireless mesh network, and a gas sensor designed for SIL2 safety applications.

    Wireless in Safety Systems

    New this year, GasSecure demonstrated a wireless gas sensor product designed for use in SIL2 certified safety systems. GasSecure's product revealed the flexibility of the ISA100 Wireless protocol through creative integration of a PROFIsafe layer over the ISA100 Wireless mesh network communication layers.

    Legacy Protocol Support

    The object-oriented characteristics of ISA100 Wireless enable support for legacy (proprietary) protocols in wireless industrial networks. The demonstration involved devices from FlowServe, Honeywell, and GE, independently transmitting control information using proprietary protocols, on a single ISA100 Wireless network.  ISA100 Wireless' object-oriented technology assures interoperability within a flexible framework, protects users' existing investments in already installed applications, and supports new protocol adoption in the future. In addition, proprietary protocol support enables device suppliers to easily participate in ISA100 Wireless networks by opening up new market opportunities while mitigating the need/costs to convert their core technology.

    Peer-to-peer Control

    Peer-to-peer control was demonstrated using an ISA100 Wireless Yokogawa pressure transmitter communicating directly with an ISA100 Wireless Flowserve smart valve positioner. Valve control communication was direct and did not pass through a gateway device or host system. 

    Duo-cast Technology

    Duo-cast technology for reliability, only available with ISA100 Wireless, was highlighted in the Yokogawa product, which demonstrated superior data throughput for critical applications such as control in the field.

    Key Technology Characteristics of ISA100 Wireless

    • True, distributed control in the field (object technology in smart devices)
    • Multiple protocols, including wired HART®, supported in a single network (object technology)
    • Functionality beyond traditional WSN applications
    • Time-enhanced, two-layer AES-128 based security, and support for all AES security levels.
    • Ease of use through provision over the air (OTA) or directly using out of band (OOB)
    • Scalable and reliable network tested to 500 devices
    • Proven reliability in congested wireless environments
    • IPv6 based technology (6LoWPAN) for industrial applications, supports the 'internet of things'

    ISA100 Wireless History

    ISA100 Wireless is the first international, industrial wireless networking standard in the ISA100 open family of standards, and it focuses on the needs of process industries. The ISA100 Wireless Compliant™ certification gives users choice between best-of-breed  ISA100 Wireless devices from  a large pool of suppliers. As a result, automation engineers are able to quickly create, modify, optimize, and scale wireless networks that are open, interoperable, and reliable for their most critical applications.

    The ISA100 Wireless standard received ISA committee approval in 2011 and formal ANSI approval in January 2012.  Headed toward internationalization, the formal standard, ANSI/ISA-100.11a-2011 was accepted as new work in IEC SC65C and as a Publicly Available Specification (PAS) IEC 62734 in 2011.
