Integrated safety functions in the Sinumerik drive from Siemens meet the requirements of safety Category 3, compliance with EN 954-1, and are an integral part of the basic system. Additional sensors are not necessary, which reduces machine installation effort and results in a "slimline" control cabinet. The scope of functions supported includes system monitoring at speed and standstill, as well as functions for safe travel range limiting and range detection.
A multi-processor architecture forms a dual-channel, system structure, and safety functions are redundantly integrated in NC, drive and internal PLC. Process variables and safety-relevant system data are cross monitored. Safety functions are available in all operating modes and communicate with the process using input/output signals.

New versions of BASF's Ecovio line are both compostable and designed for either injection molding or thermoforming. These combinations are becoming more common for the single-use bioplastics used in food service and food packaging applications, but are still not widely available.
For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This radio show will show what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
