General knowledge of CAN bus (Controller Area Network) is
required in order to understand the document. Furthermore, the
planning and use of measuring and control technology and the
CAN bus (Controller Area Network) requires technical specialist
knowledge, which is not communicated in this document.

The CAN bus is an industrial fieldbus designed for stringent safety
requirements. The CAN bus is produced in line topology. Line top‐
ology means that there are only very short connection cables
leading to the end devices from one backbone, which is up to 400
m in length. You must avoid using a star topology or creating
islands with more than four end devices. All M12 round plug con‐
nectors are water- and dust-proof to IP67 when fully screw-con‐
nected. When installing, you must only tighten the M12 round plug
connectors by hand. If using a tool, you must take care to ensure
