EC: IndraControl L85 CNC Controller with Multi-core Processor

Machine and Embedded Control - CNCs, board-level products: The IndraControl L85 is a CNC controller with multi-core processor that establishes new levels of sophistication, performance and processing power for advanced multi-axes CNC applications. This is a Control Engineering 2013 Engineers' Choice Awards Honorable Mention.


The IndraControl L85 is a CNC controller with multi-core processer that establishes new levels of sophistication, performance and processing power for advanced multi-axes CNC applications. This is a Control Engineering 2013 Engineers' Choice finalist.Enhancing productivity while reducing energy consumption, two key CNC operators requirements fully served by the advanced IndraControl L85 CNC controller. The IndraControl L85 is equipped with 16 MB SRAM and its multi-core processor has two 1.2 GHz CPU. The IndraControl L 85 multi-core processor was designed especially for machines with many axes and complex machining production processes that utilize multiple production technologies in a single work piece clamping.

Intelligent distribution of control sequences to the multi-core processor architecture delivers the added performance necessary to execute programs even faster. The control system reaches a CNC interpolation time that ranges from 0.25 ms to 1 ms, which decreases auxiliary process times and enhances productivity.  The IndraControl L85 controller has been designed to run the Rexroth IndraMotion MTX CNC advanced solution with integrated IEC 61131 PLC. The design of the IndraMotion MTX Runtime-system allows the execution of NC- and PLC-tasks in parallel, each on its own core of the processor -- enabling the performance of both systems (NC and PLC) to more than double.

The IndraControl L65 is equipped with an Ethernet field bus interface for multi-protocol operation, so manufacturers can choose between Profinet and Ethernet/IP. Depending on the specific system configuration, Sercos III, Profibus, Profinet, or EtherNet/IP can be configured to exchange data on the sensor-actuator level. Drive level communication is via Sercos III interface with Ethernet; so operators can control electrical and hydraulic motion with I/O and pneumatics, tightly synchronized with the interpolation update rate on a single bus.

The IndraMotion MTX platform also offers an optional energy monitoring module created to take advantage of the IndraControl L85's power. Operators can document the energy consumption of drive axes or ancillary units, even measure energy consumption per work piece.

Annual Salary Survey

After almost a decade of uncertainty, the confidence of plant floor managers is soaring. Even with a number of challenges and while implementing new technologies, there is a renewed sense of optimism among plant managers about their business and their future.

The respondents to the 2014 Plant Engineering Salary Survey come from throughout the U.S. and serve a variety of industries, but they are uniform in their optimism about manufacturing. This year’s survey found 79% consider manufacturing a secure career. That’s up from 75% in 2013 and significantly higher than the 63% figure when Plant Engineering first started asking that question a decade ago.
