HART to MODBUS Gateway

There many HART smart instruments installed throughout all manufacturing facilities, many of which are multivariable instruments which have additional process variables that are available via the HART signal.

When you need access to these additional HART variables and diagnostic data, but don’t have a HART based DCS or asset manager, consider the HCS HART Concentrator System. The HCS polls between one and 16 HART smart instruments on one twisted pair and maps all of the process variable and diagnostic data to an internal MODBUS memory map. This then allows the HCS to be polled by a MODBUS RTU host making all of the HART data available. The HCS is approved for installation in Class I Div 2/Zone 2 areas and supports both RS-232 and RS-485 physical layer networks. The HCS is configuring via a free Windows PC program and sets up in just a few minutes.

Key Attributes:

  • Polls between one and 16 HART instruments and converts data to MODBUS RTU
  • Class I Div 2/Zone 2 approval
  • -40 to 85C ambient operating temperature
