bus errors
Basically, the reliability of an FT1.2 interface can be verified by the bus monitor of the ETS. If the
FT1.2 interface works properly, it can be concluded that this will be the same with the Enertex®
EibPC.
Figure 12: Problems caused by an excessive rate of telegrams when using an FT1.2 interface
To check if your project generates such a rate of telegrams that messages are already lost at the
hardware level, proceed as follows:
1.
First, connect the FT1.2 interface to the ets.
2.
Open the project in the ets and start the
bus monitor
. Be careful
not to use the group
monitor
of the ets.
3.
If the bus monitor of the ets displays telegrams with a green background (Figure 12), the
installation is not free of problems. In this case, reduce the frequency of the telegrams by
parametrizing the respective actuator with telegram rate limitation.
4.
If the previously noticed faulty telegrams do not appear any more, you have achieved an
error-free installation relating to the traffic of the KNX
TM
bus and are now able to connect
the FT1.2 interface to the Enertex® EibPC.
