Eibtelegramm
This function creates KNX telegrams at lowest application level. For instance, devices can be
addressed with their physical address, which is the case of the programming of application data. The
Enertex® EibPC internally works in the group message mode and therefore only logs group
telegrams sent to a group address. Should other messages (e.g. sent to a physical address) is
observed in the integrated bus monitor of EibStudio. In order to watch such telegrams, use the ETS
bus monitor with a bus monitor enabled interface. Such interfaces are:
●
EIBMarkt IF-RS232
●
EIB-IP-Router N146 (Work with ets bus monitor and in routing-mode)
●
EIB KNX IP interface PoE (Work with ets bus monitor)

b) routing-Counter Bits 4..6
Counter 7:
A telegram will be sent without change through any coupler
Counter 6..1:
A telegram will be sent through any coupler, but
the counter will be decremented by 1 when passing it
Counter 0:
A telegram will not be sent through any coupler
c) The length of the given data Bits 0..3
The length is calculated by the given data and therefore this will be calculated
properly by the Enertex® EibPC itself. The given value will be ignored.
