A HART communicator is a handheld or software-based device used to communicate with and configure smart field devices that use the HART (Highway Addressable Remote Transducer) protocol. The HART protocol is a digital communication protocol superimposed on a traditional 4-20 mA analog signal. This allows for two-way communication with the field device without disrupting the primary 4-20 mA signal used for process control. The HART communicator's primary function is to access and modify the parameters and settings of HART-enabled field devices, facilitating commissi....
