PLC Family tackles wide array of machine applications
Rexroth’s IndraLogic XLC PLC family enables scalable, controller-based and embedded PC solutions in conjunction with the company’s latest IndraControl device platform. Industrial PC-based hardware variants will round off the device portfolio in 2011.
Rexroth advanced the PLC programming using state-of-the-art PLC kernel, IndraLogic 2G, integrated homogeneously into the company’s IndraWorks software tool and the multitasking runtime system. This allows users to take advantage of many new functions for creating modular software projects in an end-to-end overall system in less time than before. Functions include convenient editor tools, object orientation as an extension to IEC 61131-3, and comprehensive function libraries as well as fast compilers for efficient generation of machine codes. The modular GATcompact (Generic Application Template) project template simplifies the process of designing new machines with enhanced software quality while reducing effort considerably.
End-to-end communication between the controller and decentralized system peripherals, such as inputs and outputs or drives, takes place via real-time Ethernet SERCOS III. Fast PLC cycles to 250 µs enable optimum response times for handling time-critical process signals. IndraLogic XLC controllers come with versatile motion control functions, integrated into the run-time systems, to enhance the previous IndraLogic systems.
With its motion control functionality, the XLC handles machine applications ranging from simple point-to-point motion to the synchronization of multiple axes that use Rexroth’s FlexProfile to integrate complex motion sequences. The graphical profile editor in the Rexroth IndraWorks software tool offers numerous offline and online functions for this purpose. Master and slave interfaces for PROFINET RT, PROFIBUS and EtherNet/IP are also available, in addition to SERCOS III, for integrating into a wide range of communication networks.
