Access and view data from HART-enabled devices, like sensors, pressure transmitters and other field instruments.

The Highway Addressable Remote Transducer Protocol (HART) protocol communicates digital data over standard 4-20mA analog current loops.

You can see measurement data in real time, configure and diagnose devices. The application allows you to send a command once or repeatedly. You can save the response or log it continuously.

You need a HART modem like ProComSol HM-USB-ISO which provides the HART data on a serial port.

Extendable command list

Universal Commands names are already included in the command list. You can add your own command names to the list using an XML file.
You can send any HART command by simply entering the command number in decimal and specifying the command payload as space-separated hexadecimal values.
