1. Introduction

USB HART Interface is a PC link that lets HART application software communicate with any HART instrument via PC´s USB port through which we can analyse and reconfigure any instrumentation device that supports HART. For example, all KROHNE devices support HART communication and KROHNE offer the PACTware (software used for managing and configuring the devices) and the DTM files (drivers to allow the PACTware recognize the devices) free of charge on their website.

2. Advantage of the HART Interface


Using the HART Interface we can easily connect any field device to a PC. Then after installing the device DTM file on the PC, the PACTware program will recognize the device and then can review device readings, modify device parameters, analyze errors, review trends and history. Also configuration can be saved to reuse it with other instruments. All that is done without interrupting the sensor readings.
