Configuration of the interface to the PLC — how the
data are transferred
The configuration steps in this section specify how the data on the higher-level PLC are
transferred. Different operating modes can be selected to this purpose. The number of
possible connections to the PLC depends on whether the UE410-EN3 is operated as a
master or slave. Depending on the setting, up to 32 PLCs can address the UE410-EN3 at
the same time.
