With the CFC block Fault Recorder Trigger, you can form a group indication of the connected
inputs. This happens because only positive edges (from 0 to 1) are recognized by the circuit
and these are combined via an OR operation

The CFC block Connector loops the values of up to 10 inputs X0 to X9 directly through to the
outputs Y0 to Y9. From 4 connections on, this Connector is more effective than the CONNECT
block.

The CFC block Status Feedback switches between the inputs a_52 and b_52 and the status
SIM_52_A at Own_a and Own_b. By allocating the input SIM_ON to 1, the status of the input
SIM_52_a is forwarded to the outputs Own_a and Own_b.
