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 http://192.168.1.200 for "channel 1" and http://192.168.1.201 for "channel 2".
The data read by the HART device are as follows:
