The iSMA-B-MG-IP device (meter gateway) has been created to convert data from Modbus RTU/ASCII and M-Bus protocols to corresponding TCP IP protocols (Modbus TCP IP and M-Bus TCP IP) and M-Bus UDP IP protocols. The iSMA-B-MG-IP meter gateway allows to use one type of these conversions or both at the same time, using the same Ethernet connection.
The iSMA-B-MG-IP allows to service up to 128 Modbus RTU/ASCII devices with unique addresses connected to a COM1 port and up to 60 M-Bus meters (with unique addresses) connected to an M-Bus interface. At the same time the iSMA-B-MG-IP can manage up to 2 M-Bus UDP IP clients, 4 M-Bus TCP IP clients, 4 Modbus TCP IP clients, which means it can effectively manage 10 clients.
The figure below shows an example of a system with iSMA-B-MG-IP.
