HART-Ethernet Converter One

(HART-Ethernet Converter One)

The EM203A HART CONVERTER device is a HART protocol converter to MODBUS TCP or MODBUS RTU over TCP, through which the readings of an arbitrary HART device (transmitter, flowmeter, etc.) can be monitored via PLC or PC directly via an Ethernet network or over the Internet. The output protocol is selected at configure time.

Only one HART device, could be read at a time, with polling address 0 and its current signal can also be used. Data extraction period from the HART device is 2 sec.

The HART converter has two autonomous (ethernet) channels, each of which has its own own settings (IP, port, Modbus number, etc.) and can be connected to two different (physical and logical) networks.

The setting of the converter is done via web interface by web browser. Default addresses are for "channel 1" and for "channel 2".

The data read by the HART device are as follows:

  • Current output value in mA (float IEEE754)
  • First parameter value (Pv) (float IEEE754)
  • Second parameter value (Sv) (float IEEE754)
  • Third parameter value (Tv) (float IEEE754)
  • Fourth parameter value (Fv) (float IEEE754)
  • UOM codes for the four parameters
  • Status
