wireless sensors - Fieldbus Integration

WIRELESS FIELDBUS INTEGRATION:
Integrating wireless device networks with an existing fieldbus infrastructure can be surprisingly daunting. This is not usually due to deficiencies of either wireless or wired, but rather a reflection of the fact that both were developed completely independent of each other. Wireless Sensors therefore provides complete solutions that not only help customers attain the benefits of wireless, but also ensure that these benefits are not offset by additional efforts required for interworking with their existing systems. Profibus DP-V1 for cyclic and acyclic data exchanges and alarm handling. The Profibus protocol is in wide use in process automation and primarily used for communication between sensors or actuators and controllers such as PLCs or PCs. Modbus-TCP and Modbus-RTU. Modbus-RTU is widely adopted by SCADA systems, usually for communication over a RS485 physical interface. For communication over Ethernet, the more recent variant Modbus-TCP exists. The Controller Area Network (CAN) is another serial bus system used for industrial automation and control applications. The CAN protocol is well known for its high transmission reliability and real-time capabilities.
For deployments in remote locations where no infrastructure exists, Wireless Sensors additionally offers a GSM/GPRS option. The extra large 64 MByte gateway buffer ensures that no sensor readings are discarded even in the event of a temporarily lost or weak cellular signal.
