3.1.2 Basic module structure
All modules have a plastic housing made of PPE. Depending on version their
overall width differs (30mm / 45mm).There is a plug on the reverse side for the
electrical connection to the back plane BUS and the slots for mechanical fixing.
The front area is subdivided into a display area and a connection/operating area.
The modules have different colour markings for faster identification.
