However, no data exchange takes place. As there is no cyclic process data, the
general error bit continues to be set.
With suitable settings, or immediately after initialization (if already set be-
forehand), the module can change to communication mode.
If the module is started in communication mode, profiles are first loaded and
quality-of-service procedures are prepared. Finally, the connection to precon-
figured devices is configured. Display LED 1 lights up green. The display of
the remaining LEDs depends on the configuration and the communication pro-
file that has been set (see Sections 2.1.1.3.1 and 2.1.1.3.2).
Before the master and slaves exchange process data, they are synchronized to
a common process data size. This is then used from then on for data exchange.
