The HART® Test System is an all-in-one HART appliance used for the development and testing of HART 4-20mA Field Devices. Developers should begin using the HART Test System as soon as communications with the field device are functional.

It is a complete development tool produced on the Linux operating system that includes the build software, test automation, application layer, and analysis software for the implementation and verification of a device’s conformance to the HART Communication standard. The system automates device testing and verifies compliance to all revisions of the HART Protocol standard. It allows the user to run their product against the same test cases run in our conformance test lab ensuring device interoperability of both wired and wireless HART-enabled devices. The system acts as the core component for all HART and WirelessHART device testing.
