The IO Controller establishes a connection to its IO Devices based on the configuration which has been given
by the user. The Application Relation (AR) includes all data needed to achieve this data exchange. A single AR
can include multiple Communication Relations (CRs). For implementation of different communication profiles,
such as PROFIdrive, the PROFINET IO contains special addressing elements. These elements are called
Application Process Identifier (APIs).
The following CRs are possible for each API.

The data exchange between the IO Device and the IO Controller occurs in a poll cycle as configured by the IO
Controller. The user is capable to set this update cycle in the IO Controller configuration for each of the IO
Devices. This results in mutual monitoring of functional operability (watchdog function). All cyclic data is
provided with a status that encodes the validity of the data.
