The uaGate 840D gateway from Softing is dealing with this challenge and, for the first time, provides access to the complete machine tool data. ![]() The uaGate 840D gateway can be connected directly to the SINUMERIK 840D sl CNC controller without requiring a system adaptation and any additional licenses. Thus, the CNC controller prevents the integration in an overall application by not providing open and standardized communication capabilities. However, when checking the requirements for a future use, it turns out that only the data from the integrated SIMATIC S7 controller can be re-used outside the machine tool, while the NC and drive data is not accessible by external applications. The SINUMERIK 840D CNC controller from Siemens has been available on the market for about 25 years and is used in many machine tools for implementing milling, turning, grinding, nibbling and punching technologies. But now, new gateway technology opens the door to external access to SIMATIC S7 controllers, as well as NC and drive data of the SINUMERIK 840D solution line. Since many machine tools, however, already have been developed years ago, these controllers often do not provide any open and standardized interface for data integration. ![]() To fully implement Industrie 4.0 applications in the future, the internal data of CNC controllers needs to be available in a digitalized way.
