The possibilities of the X20 System can be explained using examples. This is a machine constellation with two variations, A and B.
All of the necessary electronic modules for machine variation A are shown in the picture to the left. The bus modules needed for variation B are also present, but electronic modules are not assembled.

Variation B shows the necessary electronic modules but the modules necessary for variation A are missing. The distribution of the free bus modules for the variations is also clear: The varying input and output modules can be very easily connected to the necessary electrically isolated groups and don’t need to be hung up in the back. The involved process needed to take apart the configuration to expand existing electrically isolated groups is also eliminated. Simply insert the electronic module and put on the terminal block.

The features included in Automation Studio™ can also be used to achieve completely optimized hardware configurations without losing the advantage of comprehensive application software for all variations. As described earlier, simply switching physical I/O points to the application program makes it extremely easy to optimize the hardware variations without even needing compilation.
