DESCRIPTION OF HART INTERFACE 9 OPTIWAVE 7400-24 C 9.1 General description The HART® Protocol is an open digital communication protocol for industry. It is free to use by anyone. It is included in the software embedded in signal converters of HART-compatible devices. There are 2 classes of devices which support the HART® Protocol: operating devices and field devices. There are 2 classes of operating devices (Master): PC-supported workstations (Primary Master) and manual control units (Secondary Master).
9 DESCRIPTION OF HART INTERFACE OPTIWAVE 7400-24 C 9.3 Connection variants The signal converter is a 2-wire device with 4...20 mA current output and HART® interface. • Multi-Drop Mode is supported In a Multi-Drop communication system, more than 1 device is connected to a common transmission cable. • Burst Mode is not supported There are two ways of using the HART® communication: • as Point-to-Point connection and • as Multi-Drop connection with 2-wire connection. 9.3.
