What these documents are not
LADV controllers are virtual. There are no CE declarations, wiring diagrams or fieldbus device files, because there is no hardware to certify or wire. The controllers are for learning, for testing logic and for preparing for commissioning; they are not real time, not safety rated, and cannot control equipment. For 3D machine scenes and guided courses, practise on EDWartens Lab.
