As concerns over global warming continue to grow, green technologies are becoming increasingly popular. Wind turbine companies provide an excellent alternative to burning fossil fuels by harnessing kinetic energy from the wind and converting it into electricity. A typical wind farm may include over 80 wind turbines so efficient and reliable networks to manage and control these installations are imperative. Each wind turbine includes a generator and a variety of serial components such as a water cooler, high voltage transformer, ultrasonic wind sensors, yaw gear, blade bearing, pitch cylinder, and hub controller. All of these components are controlled by a PLC and communicate with the ground host. Due to the total integration of these devices into an Ethernet network, one of our customers in the wind turbine industry needed a serial-to-Ethernet solution that can operate reliably for years without interruption.

A startup company was developing a product which provides service partners with an integrated e-services platform that allows customers to remotely monitor and control devices in their home or business. In order to complete their project, the startup needed a control system that could monitor and control the many different devices used by their potential customers, preferably with an open protocol for greater flexibility. SNMP was their first choice, as it is commonly used and well understood in the IT field. The next step was to choose an I/O server to connect to the sensors in a home automation system. System Requirements - Open Ethernet-based procotol - SNMP protocol for I/O control - Compact size to save space - Long-term support and services
