PROFIBUS connection - devices with M12 connectors

The electrical connection of the PROFIBUS is easily performed using M12 connectors. Ready-made
connection cables are available as accessories both for connecting the incoming bus as well as for
connecting the continuing bus (see chapter 14 "Accessories").
For all M12 device models, the connection is made via the two left, B-coded connectors BUS IN and
BUS OUT (see Figure 5.2).
