New functions have been added to the Step 7 engineering software, which contain an XML interface for exchanging data with CAE systems. This will allow for the simple transfer of data from CAE systems. When CAE data is imported, the user is supported by plain text messages to enable the data to be adapted in the event of data conflicts or gaps. It also provides users with a change management system. Siemens Automation and Drives, Nuremberg, Germany, www.siemens.com.
