Communication Architecture Examples with Modbus SL Hub
Modbus SL Hub Stacked with IFE Server and IFM Interface
Modbus SL hub can be directly stacked with IFE server or IFM interface with the help of stacking accessory (TRV00217) as shown in the following architecture. In this architecture, both 24 Vdc supply and Modbus connection flows via the stacking accessory.
