Wire the required input and output modules for the digital bus inputs and outputs. The output signals of the
modules must be configured in accordance with the levels of the circuit-breaker actuators.
Fig. 13 illustrates this connection with reference to a SIMATIC ET 200 U with an input signal level of
24 V DC and an output signal of 230 V AC.

This assumes that conventional copper conductors are used for PROFIBUS-DP. If fiber optic conductors
are used, converters from fiber optic to copper conductors must be fitted.
