Validity period of the process data
Data sources that write data to the input area of the central memory
are called producers because they produce process data. The Data
Broker collects this data and copies it into the output area of the
central memory. From there, the data is sent to its target, the so-
called consumer, via the corresponding interfaces.

Distribution to producers/consumers
Process data is normally exchanged cyclically between producers
and consumers. If a producer fails (e.g. a connector is removed or a
cable is broken), the consumer must be able to deal with this
situation appropriately. For this reason, you can define in advance
which values the producer will receive in exchange for the failed
process data.
