HART-Ethernet Converter Multi
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 converter can be connected to eight HART devices in "multidrop" mode, with their polling address being between 1 and 15. If the HART device is only one, its number can be 0 to 15. Data retrieval period is equal to the number of devices multiplied by 1.5 seconds.
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:
