SMG-5521 User Manual Ver. 1.0 1.2 Modbus Gateway Figure 1-1 Modbus Gateway The communication range of the Modbus RTU/ASCII device is restricted. However, the Modbus Gateway extends this range by collecting data from the Modbus device and transmitting it securely to the Sollae Cloud via the Internet. Within the Sollae Cloud platform, the data is efficiently managed, stored, and visualized in diverse ways.
Product Overview 2.1 Product Overview The SMG-5521 serves as an industrial Modbus Gateway, connecting your Modbus RTU/ASCII devices/sensors to the Sollae Cloud. Through the Sollae Cloud's web interface, you gain the ability to both retrieve data from and control your Modbus RTU/ASCII devices/sensors.
