Autem, founded 1993 in Germany, has developed intelligent and high quality software tools to analyze and diagnose automation systems. The software tools are capable of analyzing signals from a wide range of PLC’s, and are able to analyze non-PLC signals as well. These are useful tools for finding and correcting systematic or sporadic errors in your automation system, without even having to learn how to use the PLC’s programming software. They are also capable of long-term data storage, from which you can graph the data, and make hourly, daily or even yearly comparisons.
