HART-IP became part of the HART specification in 2012. But what exactly is HART-IP?
Let's first start with HART. HART is a command/response protocol. A host issues a command and a device responds. When there are many devices in an installation and a host is communicating with many of these devices, the host needs to know the name or address of the device it wants to issue a command to. This addressing scheme is defined in the HART protocol specification.
When internet protocol, or IP, is built into the device the addressing scheme defined by HART is no longer required. Rather, IP-addressing is used and each device is assigned an IP address. It's really as simple as that, HART-IP is the same as HART, but with IP addressing.
