Example:
Double reading and signal processing in two channels and diagnostics by means of
cross comparison in the DCS..B option (PES).
Option DCS..B ensures comprehensive diagnostic functions to achieve as high as
possible DC values (Diagnostic Coverage). These functions are executed permanently
or optionally (cross fault monitoring by means of pulse detection). You can use the DC
values for the input sensors given in chapter "Diagnostic values" for a safety-relevant
evaluation of the overall system.
