Applied in M2M (machine-to-machine) communication, AirGate-GPRS enables a Modbus RTU network to be monitored by more than one master. A remote master communicates using Modbus TCP through the Internet, reaching AirGate-GPRS through its GPRS connection to the cloud. A second master can be locally connected to a SCADA system using the USB port. One of its RS485 ports can be configured as a slave and connected to a third master, like an HMI, or like a master to start a new Modbus network segment with additional slaves. The other RS485 port will always connect to the main RS485 network segment, containing only slaves. Routing and multiplexing Modbus packets through its four communication interfaces adds innovative functionalities with minimum performance loss.
