MODBUS is very popular in the oil and gas upstream market while loop-powered HART transmitters still dominate and minimize your wiring. The problem is combining the two protocols effectively and economically.
The Moore Industries HCS HART Concentrator System HART-to-MODBUS RTU Converter is a very popular solution. The front-end of the HCS is a HART master which polls each of the HART devices grabbing all the Dynamic Variables and all the diagnostic bytes if desired. The data is stored In MODBUS registers waiting for the SCADA or RTU to make the request. The communication physical layer is RS-485 serial.
Should Ethernet communications be preferred instead of serial, the HCS has a sister product, HES HART to Ethernet Gateway System, which uses MODBUS/TCP over Ethernet
