The EASY242 is a PLC core module with CODESYS PLC runtime system, integrated CANopen master / slave functionality and visualisation. In addition, a variety of software drivers and libraries for special functions such as serial interfaces, evaluation of encoders, pulse width modulation, positioning of stepper motors, interrupt handling and much more are integrated in the PLC operating system. The multitasking capability of the EASY242 makes it very attractive.

Via the serial interface a visualisation with control panels of the frenzel & berg electronic VISU-Pxxx series is possible. The system is particularly suited for building control systems or applications that require a responsive graphical user interface. The module is pin compatible to the systems EASY235, EASY237 and EASY238, so that a basic hardware can be adapted by replacing the CPU to different demands. The module is the ideal platform to realise your own controls with CODESYS visualisation.

Since the software is fully implemented and tested, the development time for OEMs can be reduced significantly by using our core modules. In combination with our CANopen chips I/O and peripherals can be extended to a complete modular system for implementing customer-specific control solutions.

Of course, we also implement customized versions with special features and libraries.
