With an installed base over 40 million instruments, HART is by far the most dominant communications protocol used in process manufacturing facilities around the world. HART embraced Internet Protocol (IP) in 2009, shortly after the release of the WirelessHART protocol. Now, as low-cost, 2-wire, Ethernet enabled solutions for field instrumentation get ready to enter the market, the time is right for HART-IP enabled wired instruments. Based on the popular Raspberry PI (3B+) system and using GitHub repositories, the HART-IP developer kit provides a path for process instrumentation manufacturers to prototype and demonstrate high speed HART-IP instruments with minimal engineering effort.
Initially configured to work with power-over-ethernet (PoE) solutions, the developer kit features a replaceable Ethernet module that will be upgraded to support 2-wire Ethernet-APL as components become available in the future. Planned upgrades also include incorporation of FieldComm Group’s OPC UA-centric Process Automation Device Information Model (PA-DIM), for interoperability with OPC UA based enterprise applications, as well as support for JSON and XML based DeviceInfo files for use with lightweight IIoT edge gateway solutions.
