Benefit :

※The ideal solution for simple automation tasks.
※Minimizes costs - replaces many conventional switching control devices.  
※Reduces time requirements – simplified wiring and panel layout.
※Saves much space in the switching cabinet - modules based on a 4 width industry standard dimension replace a wide
     variety of relays, timer switches and contactor relays.
※Furnishes the widest range of capabilities and successful implementation of extensive applications with the option of
    selecting from 70 integrated functions and linking up to 512 of them in the user program.
※Additional external text display extends the possibilities for operator control and monitoring.  
※Password protection – Protects your engineering IP.
※70 integrated, pre-tested functions – No additional devices, such as elapsed time counter, are required.
※Linking of 512 functions is possible – Extensive applications can be implemented without restrictions.
※Display of message texts, action items and current values as well as direct modification of the values on the display .
※Retentive data memory – Protects current values against loss in the event of a power failure.
※Together with the xLogic software, configuring of the xLogic is simply intuitive: program generation, project
    simulation
  and documentation are accomplished using drag and drop functionality, allowing maximum ease of
    operation
