4.1 Example of a flowchart
The following figure shows an example of a flowchart for redundant I/O modules
and the signal processing in the AS.
Note
The example shows the use of two sensors. In the process industry, the
connection of a sensor to a redundant module pair is also typical
(see chapter 2.3).
