HART is an industrial standard with a very large installed base worldwide. It is a “smart” technology, i.e. it supports the simultaneous transmission of a 4...20 mA analog signal and digital communication over the same pair of wires.
In almost all applications the HART signal is used for parameterization only. With the appropriate tools, however, HART puts continuous device monitoring, real-time device diagnostics and multi-variable process information for new and old devices within your grasp.
Exploit the potential of HART with us as your partner:
Over 20 years experience with a proven technology
Comprehensive range of HART measuring instruments
Advanced diagnostics and intelligent multivariable devices
Simple commissioning and device management
Simple integration into control systems
Auxiliary hardware and handheld
Worldwide service and support
There are three basic ways of integrating the measurements provided by HART devices into a control system:
Point-to-point connection of the 4...20 mA signal
Connection via a remote I/O or HART multiplexer to a superordinated bus system, e.g. PROFIBUS
On rare occasions, connection of a HART multidrop bus to a HART I/O card
Only in the two latter cases is the full device information available to the control system.
HART device information (parameters, status etc.) can be accessed by:
An FDT frame, e.g. FieldCare, which requires a so-called DTM for each device type
A DD/EDD operating tool such as Field Xpert SFX350/SFX370 handheld, Asset Management Solution (AMS) and Process Device Manager (PDM)
We offer DTMs, DDs and EDDs for all our HART devices and ensure they are integrated into the above-mentioned tools.
The device description files and certificates can be obtained from the download area of each product.
