Device Smart Communicators

• FDT technology gives users centralized access to all devices.
• FDT technology provides a common environment for configuring, operating, or maintaining any devices.

FieldMate application software runs mainly on a notebook PC and is a key component epitomizing Yokogawa's asset excellence (AE) concept together with Plant Resource Manager (PRM). FieldMate is available in basic and advanced versions. The basic version enables parameter setting and adjustment as well as status check of a field device by directly connecting a FieldMate-installed PC to a Highway Addressable Remote Transducer (HART) device or FOUNDATION™ fieldbus H1 device.

FieldMate is field device adjustment and configuration software applying Electric Device Description Language (EDDL) and Field Device Tool/Device Type Manager (FDT/ DTM) technologies. The FDT/DTM is being standardized and disseminated by the FDT Group, a nonprofit organization. Yokogawa is also aggressively participating in those activities.

Yokogawa FieldMate Advance software can configure and adjust intelligent field devices from different manufacturers and on multiple fieldbus protocols. This flexibility is possible thanks to the use of Field Device Tool (FDT) open standards developed by the FDT Group, of which Yokogawa is a board member.

This article describes how a multivariable pressure transmitter with built-in dynamic compensation can compensate for many of the errors and inaccuracies that can occur in differential pressure based flow measurements. It also shows how the built-in computing and communications capabilities of such modern flow meters ensure ease of integration with field device tool (FDT) and device type manager (DTM) tools in monitoring and control systems.
