The primary master is generally a distributed control system (DCS), programmable logic controller (PLC), or a personal computer (PC). Two masters can connect to each HART loop. More than 105 manufacturers support HART with a choice of more than 170 different field instruments. Introduction HART is a master-slave communication protocol, which means that during normal operation, each slave (field device) communication is initiated by a master communication device. In Multi-Drop mode, sev-eral HART instruments can be bussed together. Today, HART is the most widely used digital communications protocol for instruments in the process control industry.

The PTQ-HART module is the perfect solution for industrial applications in chemical and refining operations, to gas and liquid distribution systems, and remote offshore monitoring stations are addressing virtually all aspects of control, data acquisition, and maintenance.

The HART protocol is supported by major instrument suppliers and the HART Communication Foundation (HCF). The database is user-defined and stored in the module to hold the data required by the protocol.

Compatible devices include a large array of field devices including pressure, temperature, metering, and many other instruments.ĭata is exchanged between the HART network and the Quantum processor backplane using the internal database contained in the module. The four ports on the module support HART master commands to interface with slave devices on their own networks. The PTQ-HART module interfaces up to 15 devices on each of four HART Multi-drop channels with a Quantum processor.
