(3d) Utilizing WirelessHART for Modular Design, Validation, and Deployment

Many organizations are using or exploring use of modular construction. Modular construction enables organizations to design, construct, and validate modules utilizing flow, pressure, temperature and other measurements along with on/off valves, regulatory values, and discrete devices. Their objectives reflect changing business conditions and the need to reduce development timelines. Once concepts are designed, which often include first principle models, these modules may be deployed for field testing. Applications include separation and absorption of liquids and gases. A key design criterion is that these modular designs must be easy to reconfigure and calibrate, add or change sensors, adjust control strategies, and reconfigure valves. They must also be easy to monitor and able to operate standalone or integrated with existing systems.

One technique that is being used to support this modular design is WirelessHART. WirelessHART includes a wide range of measurement devices, a growing number of wireless actuators, and THUMs, which may be added to wired HART devices, which in-effect converts them to WirelessHART devices. This presentation addresses how to apply WirelessHART to modular design. A combination of event triggered, and periodic execution is used to address control of faster processes such as liquid and gas flow using wireless transmitters and wireless valves. Examples are used to demonstrate how this capability has been incorporated into working systems. Information will be provided on the control performance achieved in field applications using wireless transmitters and/or wireless throttling valves.
