  • Fieldbus Wars continue: EDDL vs. FDT/DTM

    Fieldbus technology expert Dick Caro predicts that as Ethernet-based control networks converge into the domain of fieldbus, there will eventually be a conflict between OPC/DX, FDT/DTM, and EDDL.

  • Don't Let Phase Changes Faze You

    Phase changes in the downstream processing or handling of solids cause many process problems that have inexpensive solutions.

  • 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.

  • Getting batch material transfers under control

    Batch material transfer control seems an easy task to carry out, but the reality is that many functions are necessary if the system is to accomplish accurate batch material transfer control. Weighing systems with device-level controls can help.

  • Efficient batch control

    Efficient batch control can be both an art and science, so act accordingly for best results, and always remember "it's survival of the fittest" out there.
