Process Automation Controls meets Wireless!
The KWJ-WSN Serial MODBUS Gateway (SMG) acts as a data concentrator for KWJ-WSN wireless sensor networks. This device allows you to connect up to 100 wireless sensing devices, per gateway, to your existing serial MODBUS RS-232C and RS-485 sensing and control infrastructures.
KWJ Engineering has recognized the importance of using open standards like MODBUS, allowing KWJ-WSN 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, KWJ-WSN SMG’s allows for seemingly unlimited wireless expansion of a traditional wired network.
A system incorporating a KWJ-WSN SMG would consists of the the following:
• MODBUS Master – PLC, SCADA, etc.
• Existing RS-232C or RS-485 Infrastructure.
• KWJ-WSN Serial MODBUS Gateway (SMG).
• KWJ-WSN Wireless Sensors
Works with KWJ-WSN 900, 868 and 433MHz
