Moore’s HCS converts HART digital protocol to Modbus RTU

North Hills, CA—Moore Industries reports that its HART Concentrator System (HCS) converts a HART digital signal to a serial (RS-485) Modbus RTU communication protocol. This permits up to 16 smart HART-capable transmitters and valves to interface directly with Modbus-based monitoring and control systems.

North Hills, CA— Moore Industries reports that its HART Concentrator System (HCS) converts a HART digital signal to a serial (RS-485) Modbus RTU communication protocol. This permits up to 16 smart HART-capable transmitters and valves to interface directly with Modbus-based monitoring and control systems.

HCS interfaces all HART parameters to Modbus. This includes the ability to monitor primary and non-primary (second, third and fourth) process variables from 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.

HCS also allows monitoring by a Modbus system of HART instrument diagnostics using field device status byte data available in HART’s digital information. This includes: smart device configuration changed; primary and non-primary variable out of limits; primary variable analog output fixed; cold start; field device malfunction; and more HART status data available.

HCS is programmed in minutes using Moore’s free Windows PC configuration software. It is housed in an industrial metal and RFI protected housing that snaps onto standard DIN-style rails.
