HCSHART HART Concentrator System RTU Converter
Brand: Yokogawa Electric CorporationThe HCS HART Concentrator System converts a HART digital signal to a serial (RS-485 or RS-232) MODBUS RTU communication protocol.
This allows HART transmitters and valves to interface directly with MODBUS-based monitoring and control systems.
Operates in Point-to-Point and Digital Multidrop HART Networks: In point-to-point HART mode, the HCS is set to monitor a single instrument.
All process and diagnostic data carried on the HART data string is converted to MODBUS RTU.
Up to 16 HART Devices Per HCS: In a digital multidrop HART network, up to 16 HART instruments digitally communicate on the same wires.
The HCS can be set to monitor any or all instruments and/or valves within the network.
Only one MODBUS address, and one communication link (such as twisted wire pair), is needed to send the process and diagnostic data from up to 16 HART devices to a MODBUS host.
