The Sense IoT Serial Modbus Gateway (SMG) acts as a data concentrator for Sense IoT long range wireless sensor networks. This device allows you to connect up to 50 wireless sensing devices, per gateway, to your existing serial Modbus RS-232C and RS-485 sensing and control infrastructures. Sense IoT has recognized the importance of using open standards like Modbus, allowing Sense IoT wireless sensors to be used in the majority of industrial applications. Modbus is often used to connect a supervisory computer with a remote terminal unit (RTU) in supervisory control and data acquisition (SCADA) systems. Modbus allows for communication between many (approximately 247) devices connected to the same wired network. Therefore, Sense IoT's Serial Modbus Gateway allows for seemingly unlimited wireless expansion to a traditional wired network. A system incorporating a Sense IoT SMG would consists of the following: • Modbus Master – PLC, SCADA, etc. • Existing RS-232C or RS-485 Infrastructure • Serial Modbus Gateway (SMG) • Wireless Sensors
