<p>WAGO's communication module extends the WAGO Energy Meters and other Modbus RTU slaves with ETHERNET access. The Modbus TCP Module’s design is based on the 879 Series Energy Meters and has the same profile as these. There are various options for connecting the communication module to the energy meters:</p><p>1. Connection to the energy meter via UART interface (one communication module per energy meter)</p><p>2. Connection via RS-485 interface (up to 32 generic Modbus® slaves)</p><p><b>Features:</b></p><ul><li>Communication module snaps onto WAGO's energy meter</li><li>Modbus TCP</li><li>Direct connection to the energy meters via RS-232 lateral UART interface</li><li>RS-485 interface for connecting up to 32 generic Modbus RTU slaves</li><li>Configuration via configuration software or Modbus<sup>®</sup> function codes</li><li>Maximum number of permitted Modbus TCP connections: 4</li></ul>
