of error
LED display The PN/BACnet LINK signals its state with the
LEDs on the front of the housing. The meaning
of the LEDs is described in section Operating

diagnostic message and possible measures.

Below you will find a list of possible error situations and the corresponding response of the
PN/BACnet LINK.
Configuration error
During configuration, defective inputs and parameters are largely detected and reported
through compilation of the TIA Portal project. If the configuration does not correspond to the
associated system, error situations arise such as configuration errors (see following section).
Configuration error
If there is a configuration error, the configuration does not match the corresponding system,
or the system configuration changes in runtime. For example, BACnet objects are no longer
accessible or devices have been removed. The PN/BACnet LINK supports locating the
cause of the error as follows:
● If a configured BACnet object does not exist, the PN/BACnet LINK runs SIMATIC
diagnostics and sets the OUT_OF_SERVICE status bit for the S7 controller.
● If a configured BACnet device does not exist, the PN/BACnet LINK runs SIMATIC
diagnostics and sets the OUT_OF_SERVICE status bits for all objects of this device for
the S7 controller.
