PROFINET-IO – star topology
The BCL 548
i
can be operated as a single device (standalone) with individual device name
in a star topology. The PLC must communicate this device name to the participant during
the "device naming".

PROFINET-IO – line topology
The innovative further development of the BCL 548
i
with integrated switch functionality
offers the option of connecting multiple bar code readers of type BCL 548
i
to one another
without direct connection to a switch. In addition to the classic "star topology", a "linear
topology" is thus also possible.

PROFINET-IO in a line topology
Each participant in this network requires its own unique device name that is assigned by
the PLC during the "device naming". For specific information, please refer to chapter "Step
5 – Configuration of the device name - naming the device" on page 121.
The maximum length of a segment (connection from the hub to the last participant) is limited
to 100m.
