Hart To Modbus Indicator
HMI, HART to MODBUS Indicator is designed to accept HART signals from field instruments in multi drop mode and convert standard variables into fixed MODBUS address registers. This is useful to accept / read exact values available for Flow, Pressure, Temperature transmitters in digital form in the control room eliminating errors in Analog input acquisition and process systems. User friendly messages to understand status of the instrument and actual values of HART slaves connected on the loop.The engineering units are acquired from the HART slaves hence reduced efforts for programming. User selectable baud rate for MODBUS Master on DIP switch. Isolated HART and RS485 port is available.
