Intelligent software functions from Rexroth increase productivity and protect know-how

The Open Core Interface allows OEMs to realize individual functions and to seamlessly integrate devices such as smartphones and tablets into machine concepts.

CNC system solution IndraMotion MTX with enhanced functionalities through Open Core Engineering

A higher productivity through intelligent functions is increasingly determining the competitive ability of machine tools. Machinery manufacturers are therefore searching for options to ensure their success with new and partially unique functions while simultaneously protecting their know-how. Rexroth fulfills these requirements within the framework of Open Core Engineering with functional advancements to the CNC system solution IndraMotion MTX.

With Open Core Engineering, Rexroth enhances the classic PLC programming by bridging the gap to IT automation. It increases engineering efficiency thanks to open standards, software tools, and function toolkits. Rexroth is now also offering machinery manufacturers the option of creating individual software functions independently, thereby allowing them to access the control via defined interfaces in real time. Therefore, the CNC specialist provides with the Open Core Interface a new interface technology for Rexroth controls. It allows OEMs to realize individual functions and thus set themselves apart from the competition. The Open Core Interface also enables the seamless integration of smartphones and tablets into machine concepts. Apps for these smart devices allow service technicians to perform wireless, remote machine diagnostics from anywhere, for example.

In a wide range of predefined function toolkits, Rexroth has modeled the application know-how in software, meaning that machinery manufacturers need only to parameterize. With the new IndraMotion MTX vcp function toolkit for volumetric error compensation, Rexroth's CNC automatically compensates for mechanical inaccuracies in the entire machining area. The three-dimensional compensation of deviations in position, straightness, rotation, and perpendicularity is a particular advantage in the case of large-volume components because errors outside of the margins are particularly cost-intensive in such cases. The necessary compensation values are recorded with a laser interferometer and saved in tables that the control system offsets in the process without performance losses. The bigger the machine workspace, the more significant the software function's correction effect. IndraMotion MTX vcp was able to improve volumetric accuracy in applications by over 90%.

The growing importance of software functions in machine tools means a correspondingly increased need to protect know-how. With the IndraMotion MTX encrypt function toolkit, machinery manufacturers and users now have a way to protect user programs from unauthorized third party access. Users can select and run encrypted programs on the machine. At the same time, the program code is saved on the control exclusively in an unreadable format. The encryption can also be additionally bound to a certain control hardware. In this way encrypted programs then only run on this one machine. Encrypted files need only be transferred to the machine. No interventions in parameters or software are necessary, giving machine users with a global production network an efficient way to protect their know-how.

In the field of machine safety, Rexroth offers additional options for increasing economic efficiency and availability. The enhancement of the CNC system solution with a safety function module from the Open Core Engineering environment and the Safety PLC SafeLogic reduce programming time and effort, because process modifications have no feedback effects on the safety control, thus allowing machinery manufacturers to realize standardized safety from the control unit to the secure drive – all with minimal time and effort.

Rexroth meets user demands for greater energy efficiency with the IndraMotion MTX cta/ega software assistant, which is integrated into the control unit. It analyzes the duration and energy consumption of each machine movement. This database then lets programmers optimize motion control to increase energy efficiency while maintaining maximum productivity.
