HART Protocol Communication Solution
Keywords:
HART protocol, protocol conversion, Modbus, Profibus DP, EtherNet/IP
Background:
HART protocol was introduced in 1985 for a communication protocol between field intelligent instrument and control room equipment. With 30 years’ development, HART technology has become very mature and has been the industry standard for global intelligent instrument.
HART technology is a master / slave protocol, the slave devices will not send a signal until the master device sends a signal, . The HART protocol can be used in a variety of modes, such as single point mode or multipoint mode, to transfer information between the HART instrument and the central control or monitoring system.
The HART protocol can have up to two master devices (first master and second master). When using the second master to control, the control/monitoring system communication of the first master station won’t be interfered.
Key Features of HART series gateways:
1. Powerful function: Support the interconnection between HART and Modbus serial/Modbus TCP, PROFIBUS DP, EtherNet/IP, etc.
2. The HART side can be configured as first or second master.
3. Supports single-point and multi-point mode at the HART side.
4. Easy to configure by configuration software-No programming required.
5. Installation: 1.38in (35mm) DIN RAIL.
6. Protection level: IP20.
For different protocol conversion applications, we have different gateways, More details, please kindly check company website (www.sstcomm.com)
