HART
Process automation with digital fieldbus technology
Smart HART®
Intelligent measurement instruments of Endress+Hauser can be equipped with the standardised HART protocol. This will enable you to use the advantages of digital communication, e. g. the configuration of instrument parameters and status display, on basis of the proven 4...20 mA technology. And this with your existing instrumentation.
WirelessHART
WirelessHART is the wireless standard of the HART Communication Foundation for use in process automation. It adds wireless capabilities to the HART protocol while maintaining compatibility with existing HART devices, commands and tools.
Endress+Hauser WirelessHART products and solutions provide you with more information about your process and plant for less cost. In many fields of application, having more information available is synonymous with being more productive. Benefit from our experience at every stage of your project: site survey, network design, positioning of gateways, selection of devices through to the integration of the process values in your selected host system.
Command classes
The HART protocol defines three command classes. The universal commands are supported by all HART instruments. Universal commands offer a basic set of functions. These functions are used for the recognition of HART instruments and for reading the digital measured value. The generally used commands offer functions which are supported by many but not by all HART instruments.
They are used to read digitally up to four measured values and to handle basic configurations like the span. The commands specific to individual devices permit the access to instrument data which is not HART standardised. Examples for this are special items of service, diagnosis information and extended maintenance operations.
Device descriptions
Device descriptions (DD) need HART masters, e. g. hand-held terminal or PC-based operating programs, in order to permit access to all of the information in a HART device. DDÆs allow HART masters the execution of routines and the interpretation of information which may only be transferred via specific commands. HART masters which are able to process device descriptions offer maximum interoperability of HART devices of the most varied manufacturers. Device descriptions are available for all Endress+Hauser instruments. They have been registered at the HART Communication Foundation (HCF).
