Wireless standard update: call for proposals, use case studies
Research Triangle Park , NC —ISA's standards committee on wireless systems for automation, ISA-SP100, issued calls for proposals (CFPs) to encourage a variety of experts to collaboratively create a new series of wireless communication standards for industrial monitoring and control. In a separate development, at Sensors Expo in Chicago, the committee announced completion of several use case studies and plans for continued efforts.
The ISA-SP100 committee is establishing standards, recommended practices, technical reports, and related information that will define procedures for implementing wireless systems in the automation and control environment with a focus on the field level. Guidance is directed toward those responsible for the complete life cycle, including the designing, implementing, on-going maintenance, scalability or managing manufacturing and control systems, and will apply to users, system integrators, practitioners, and control systems manufacturers, and vendors.
Two working groups of ISA-SP100, WG3 and WG4, issued calls for proposals to provide input to the committee and encourage a variety of experts, who may not be members of ISA-SP100, to participate in this process. The CFP process is intended to solicit input that addresses and helps solve critical issues associated with the deployment of wireless technology for industrial automation. During the evaluation process, preference will be given to proposals where sufficient technical detail and performance data is readily available to assess the validity of claims.
WG3 is developing ISA-100.11 on wireless communication standard(s) optimized for industrial loop control. Typical applications include: automatic, direct control of primary actuators for process loops in a plant; controlling flow, temperature, pressure; cascaded loops controlling a process variable (such as low frequency temperature loops); coordinated interlocks between automation cells; closed loop speed controls for rotating equipment; and mobile workers with handheld devices manually initiating process actions. WG4 is preparing ISA-100.14, wireless communication standard(s) optimized for monitoring and logging. Typical applications include: process monitoring, equipment health monitoring, asset management, file uploading/downloading, validation, and potentially open-loop control. The groups say they intend to be open and collaborative, with the goal of achieving consensus when possible, to create the best possible wireless communication standards for industrial monitoring and control.
The use case study allows end-users to describe their specific industrial wireless application requirements in their own words, and will provide structure to ensure adequate detail for the committee's working groups. The use case project, a task under the Marketing Working Group of the committee, is well underway with nearly a dozen studies completed from a variety of industries, such as oil refinery, oil drilling platform, food processing plant, or a paper mill. Tasks that wireless might accomplish include tank level monitoring, perimeter security monitoring, temperature or pressure sensing, etc. Quality of service is also covered; a user might require periodic reporting of monitoring valves, alerting and alarming services, or device diagnostics and maintenance. ISA and Chevron hosted a free seminar in San Ramon, CA, July 26, for end-users interested in participating in the studies; future seminars are planned.
