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.
