5.1 Network topology

Reader connector system
A reader always occupies one M12 socket on the RF18xC/RF18xCI. You can connect the
reader to the communication module using a preassembled cable. The connection cable is
available in lengths of 2, 5, 10, 20 and 50 m as standard. If necessary, these can be extended.

5.1 Network topology
The communication network can be designed as line/series, star or ring topology. Also, note
the information in the section "Supply voltage and PROFINET IO loop-through (Page 46)".
Figure 5-2
With a line/series topology, remember that if the communication connection of a
communication module to the controller is interrupted, the communication connection to all
downstream communication modules is also interrupted.
