HART Overview HART Technology It has undergone continuous development, up to and including automation products now shipping with built-in Wireless HART Communication. How does the HART protocol work? HART Communication protocol What is a Bell 202 telephone communication standard? Frequency Shift Keying HART Networks The HART Protocol allows digital communication with field devices in two …
The WirelessHART™ standard provides a robust wireless protocol for the full range of process measurement, control, and asset management applications. It adds wireless capabilities to the HART Protocol while maintaining compatibility with existing HART devices, commands, and tools. A wirelessHART device uses nominal 2.4GHz transmission frequency using IEEE 802.15.4 standard radios because meeting these criteria allows WirelessHART …
What is HART protocol? HART (Highway Addressable Remote Transducer) Protocol is the global standard for sending and receiving digital information across analog wires between smart devices and control or monitoring system. HART is owned by independent non-profit  HART communication foundation. HART is now a global standard because digital information from HART devices can simultaneously communicated with the …

What is HART? HART stands for highway addressable remote transducer. HART is a communication protocol for the process instrumentation. It is the global communication standard in process instrumentation. A transducer is a device that is capable to convert the physical variable into a similar electrical signal. HART communication protocol is the most used digital communication …
What is a foundation field bus? A field bus can be described as the connection between industrial devices. The major purpose of a field bus is to replace the point-to-point link between the field devices and control system, instead of that Fieldbus would provide a digital link. In a field bus, the transfer of information …

A HART communicator is a portable device, based on HART communication protocol. A HART communicator works as a secondary master in a control loop. A field communicator supports both HART and Foundation Fieldbus devices. HART communicator devices are used to check variables online and for calibration purposes. The communicator is portable, thus wireless runs in …
Introduction HART is a master-slave communication protocol  , which means that during normal operation, each  slave (field device) communication is initiated by a master  communication device. Two masters can connect to each HART loop. The primary master is generally a distributed control system (DCS), programmable logic controller (PLC), or a personal computer (PC). The secondary master can be a handheld terminal or another PC. Slave devices include transmitters, …
