Fieldbus Foundation issues preliminary specification for ISA100.11a transducer block
August 6, 2013 by Manufacturing AUTOMATION
The Fieldbus Foundation has issued a FOUNDATION fieldbus Preliminary Specification (PS) addressing fieldbus transducer blocks for ISA100.11a wireless devices. ISA100.11a is an industrial wireless networking technology standard developed by the International Society of Automation (ISA).
As part of the FOUNDATION for Remote Operations Management (ROM) solution implementing wireless and remote I/O, the new technical specification defines a fieldbus transducer block used within FOUNDATION for ROM devices to communicate with ISA100.11a instruments. In addition, it describes the method for configuring tools and asset-managing hosts to access ISA100.11a devices, as well as structures to identify and maintain device status in ISA100.11a networks connected to FOUNDATION for ROM devices.
The new transducer block specification will enable automation end users to interface ISA100.11a devices to FOUNDATION fieldbus for better integration with a control system, or with FOUNDATION devices. The technology also supports a networked method for asset-managing hosts to access an installed base of ISA100.11a devices for configuration and maintenance purposes.
HSE provides an efficient way to bring large concentrations of discrete and analog field I/O from modular devices back to the control room using a high-speed HSE connection. Employing HSE equipment functioning like a smart remote terminal unit (RTU), the technology brings all forms of conventional I/O into the native fieldbus environment easily. This solution makes discrete I/O, analog I/O, H1 fieldbus, HART® and WirelessHART available over common Transport Control Protocol/Internet Protocol (TCP/IP) networks. The addition of the new ISA100.11a transducer block further expands the integration of process instrumentation within a FOUNDATION control system infrastructure.
