If you have never used Selmostudio before please follow the link:
Here you can see the modelled demo project in the Selmostudio.
In this demo we have 6 steps and 8 zones.
The steps describe how the machine works.
The zones represent all machine states and contain all important information for the system.
For safety reasons, certain components are locked against simultaneous movement.
For example, the ejector should only extend if the lifter is in the work position.
