Gateway Mode
The iSMA-B-AAC20 controller can work as a Modbus TCP/RS485 gateway. By default, this option is enabled until there is no ModbusAsyncNetwork component in the Sedona application or the component is disabled (ModbusAsyncNetwork -> Enable slot in the false state).
The RS485 communication parameters can be set up by:
Controller configuration web page (RS485 Configuration tab);
ModbusAsyncNetwork component (remember to set false in the Enable slot);
Controller Modbus register table (see the iSMA-B-AAC20 Modbus table chapter).
