Motion logic and robotics controller has flexible profile

Rexroth MLC motion logic controller with Version 10 firmware is based on a powerful one-gigahertz PAC controls platform that provides high-performance motion logic and robotics capabilities.


The Rexroth MLC motion logic controller with Version 10 firmware is based on a powerful one-gigahertz PAC controls platform that provides high-performance motion logic and robotics capabilities.

Rexroth MLC motion logic controller with Version 10 firmwareThe advanced platform supports real-time Ethernet communication on Ethernet platforms, including SERCOS III, EtherNet/IP and ProfiNet for interfacing with connecting controls, drives, I/Os, safety, HMI, web and machine-to-machine synchronization, which helps to lower the controls cost and simplify integration for OEMs, systems integrators and end users, the company says. The MLC motion control, Version 10, has Web-based Service & Engineering Tool for easy access using a web browser to access the system data. With configuration tools for maintenance and commissioning. The system status and diagnosis of control hardware, drives and communication interfaces can all be viewed. Also, available is the parameter editor, PLC variables, and electronic name plate data.

It uses IndraLogic 2nd Generation (2G) PLC editor that offers the following extensions and enhancements: Object orientated programming in project structure, new data types, new operators and variables. IndraLogic 2G supports standard IEC 61131-3 program languages such as: function block diagrams (FBD), ladder diagrams (LD), instruction lists (IL), sequential function chart (SFC), and structured text (ST). It offers a new visualization concept for testing and monitoring functions as well as additional features. It is suitable for the most sophisticated packaging and high-speed robotics applications. The processor can control up to 32 robotic kinematics concurrently and up to 64 axes of motion and logic on a single controller. The latest firmware also provides advanced Flex Profile camming capabilities to help reduce engineering time and provide automatic cycle time optimization of machines and packaging lines.

With Flex Profile, cams can be multi-segmented and cycle times can be automatically optimized for velocity, acceleration, position or time to avoid having to rebuild cams each time a parameter changes. Provides masters as an axis, as a specific time, or a combination of both. By changing values in the segments the profile can be easily modified to accommodate any changes in products. It can generate PLC function blocks for online creation of FlexProfiles, CAM preview with several axes simultaneously and provide definition of FlexProfile events.

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.
