HART communication adopts a half-duplex communication mode, which is characterized by digital signal communication on the existing analog signal transmission line, which is a transitional product in the transition from analog system to digital system, and thus has a strong transition period in the current transition period. The market competitiveness has been developed rapidly. HART specifies a series of commands that work as commands.
HART has three types of commands. The first type is called a general command, which is a command that all devices understand and execute. The second type is called a general behavior command. The functions provided can be implemented in many (though not all) of the field devices. Such commands include the library of functions of the most commonly used field devices; the third type is called special device commands, so that work can be implemented in some devices to achieve special functions. Such commands can be used both in the Foundation and in the Unique to the company that developed this order. These three types of commands can usually be found in one field device.
The
HART Communicator (https://www.china-transmitters.com/)combines the traditional functions of a multi-function calibrator with HART communication functions to perform routine calibrations including voltage, current, thermocouple, RTD, frequency, resistance, and pressure. Used to communicate directly with all popular HART smart transmitters and as a multi-function communicator for maintenance and diagnostics of HART instruments. It can be used to complete almost all on-site instrument inspection and debugging work, including fault diagnosis, routine maintenance, driving debugging, calibration and so on.
