Moore Industries HCS HART Concentrator System

The HCS HART Concentrator System from Moore Industries converts HART digital signals to the serial (RS485 or RS232) Modbus RTU communications protocol. It monitors a single instrument in point-to-point HART mode or it can allow up to 16 HART instruments to digitally communicate on the same wires in a digital multidrop HART network.

The HCS maps all HART variables to Modbus registers so Modbus host systems can have access to the multiple HART process variables found in instruments such as smart multivariable mass flow, pressure, pH and temperature transmitters; Coriolis, magnetic, ultrasonic and vortex flow meters; radar and hydrostatic level transmitters; and valve positioners and damper operators.

The HCS also allows a Modbus host system to monitor critical HART instrument diagnostics by using the field device Status byte information. HART status data available includes smart device configuration changes; primary and non-primary variables out of limits; primary variable analog output fixed; cold start; and field device malfunction.
