CX controller with extension via EK1100
If, in the case of a CX controller with a PROFIBUS/PROFINET interface, the E-bus employed is extended by
an EK1100 coupler, an EL9930 must be used behind the EL6910 and in front of the EK1100, as otherwise
the PROFIsafe telegram would leave the E-bus via EtherCAT.
