  • EDDL enhancements gain momentum

    Several major vendors have now announced plans to fully support enhancements to the electronic device description language (EDDL) used by HART devices, reports Ed Ladd of the HART Communication Foundation. These enhancements will allow users to interact with their intelligent devices in new ways. They ease configuration, even of complex instruments, and support storage of historical data for troubleshooting and diagnostics.

  • Software Drives OEM Toward Efficiency and Energy Savings

    ABB designed software for its ACS800 drive so Curtis-Toledo could improve the operation of its rotary-screw compressors. The customized software can control the system pressure, air delivery, oil temperature and duty cycle directly from the drive.

  • Process Engineering: HART Offers Value in Plant Control Systems

    There's a myth in plants that HART offers little for Plant Control Systems and Enterprise Level Networks. But Ed Ladd from the HART Communication Foundation writes that by accessing the data in HART devices on a "full-time" routine basis increases performance, integrity, and reliability of plant control and enterprise level systems.
