8.7 Reading the Analog Values

8.7.1 Messages of the Analog Inputs

The transmission types for the analog inputs are described in the following:

acyclic, synchronous: The transmission is initiated if a SYNC-message has been received (PDO-
transmission type 0) and data has changed.

cyclic, synchronous: The transmission is initiated if a defined number of SYNC-messages have
been received (PDO-transmission type 1...240).

event controlled, asynchronous: The transmission is initiated if the state of selected inputs has
changed (PDO-transmission type 254, 255).
