Transfer of KNX bus state
If the special function "KNX bus state" is configured, the current KNX bus state is transferred
directly to the LOGO!. This means that the value is "1" if communication to KNX is OK. The
value is "0" if an error has occurred.
It may be the case that an error on the KNX bus is only detected following a delay of
several seconds.
The last transferred KNX bus state is retained in the event of loss of the Ethernet
connection.
