The modularity of the hardware and software portfolio enables users to configure a controller that exactly matches the performance requirements of their system and allows subsequent extensions and modifications – such as for example a retrofit of Condition Monitoring functions, without great expense. The operation and maintenance of modern wind turbines incurs considerable costs. To maintain competitiveness, operators must minimise failure risks, reduce maintenance costs and increase the availability and energy efficiency of the system. This is where Condition Monitoring enters the game: seamless monitoring of gear units and System-integrated Condition Monitoring • Time-synchronous data logging in

Suppliers generators is generally recommended, not just for offshore wind turbines or systems in remote regions, but for all. Beckhoff marries the powerful processors of modern PC technology together with EtherCAT as fast communication system, integrating Condition Monitoring functionality seamlessly into the controller. The vibrations of bearings or electrical machines are picked up by standard measurement terminals from Beckhoff and transmitted to the controller via EtherCAT. Configuration, programming and diagnostics are carried out within one system using TwinCAT. System-integrated Condition Monitoring With improved error detection and holistic system analysis capabilities, the control system-integrated Condition Monitoring from Beckhoff is superior to conventional hardware-based Condition Monitoring solutions. High-frequency data acquisition via EtherCAT Terminals For grid voltage monitoring, two EtherCAT Terminals are available from Beckhoff: the EL3783 power measurement terminal with oversampling function for status monitoring in a 3-phase AC network, and the EL1252 digital input terminal with timestamp function for the chronologically precise detection of binary control signals. The retrofit of a wind turbine with Condition Monitoring can be realised by simply adding a terminal block with the corresponding EtherCAT measurement terminals to the turbine controller. A multi-functional input for analog measurement technology is available in the EL3751 EtherCAT Terminal. The EL3632 enables the direct connection of various acceleration sensors via an IEPE interface and performs high-precision vibration measurement. Strain gauges (SG) can be evaluated via the EL3356-0010. The raw data are recorded synchronously (
