4 General Information
The RESI-MBUSxLVL-ETH gateways are designed for integrating MBUS smart meters via Ethernet interface
into an own building automation or industrial solution with a host system, which is able to interpret the MBUS
standard protocol.
The converters offer the following features:
RESI-MBUSxLVL-ETH: Serial communication with MBUS smart meters with 300-57600baud, even
parity, 1 stop bit.
Different versions of gateways for individual situations:
RESI-MBUS24LVL-ETH: Gateway for maximum of 24 MBUS meters
RESI-MBUS48LVL-ETH: Gateway for maximum of 48 MBUS meters
RESI-MBUS64LVL-ETH: Gateway for maximum of 64 MBUS meters
Transparent mode: The incoming data on the socket is directly written to the serial line. The received
serial characters are directly written to the socket
MODBUS/TCP to MODBUS/RTU conversion: The incoming MODBUS/TCP frame is internally converted
to a MODBUS/RTU frame and send to the serial line to the corresponding MODBUS/RTU slave device.
The serial answer of the MODBUS/RTU slave device is received by the gateway, converted into a
MODBUS/TCP frame and send to the socket.
Gateway configuration via special MODBUS/RTU or MODBUS/TCP frames or special ASCII ocmmands.
IP configuration via DIP switches and web page
Serial interface is electrically isolated from the Ethernet interface
Ethernet connection via 10/100Mbit Ethernet interface
