Engineering with ETS
Notes

When using the ETS engineering tool, e.g. in plants with third-party devices, the
ETS product database of Synco bus devices must be imported into ETS.
Note especially the following when engineering with ETS:
ETS does not allow access to the LTE filter table (to filter zone addresses).
ETS allows access to the S-Mode filter table (to filter group addresses).
Fixed group addresses are defined in the KNX standard for some system
functions, including, e.g., group address 30/3/254 for the system time and
30/3/250 for fault information.
Group addresses30/3/254 and 30/3/250 are factory-set in the Synco bus
devices.
When downloading new group addresses into Synco bus devices, the group
addresses 30/3/254 and 30/3/250 referred to above must be set up in the ETS tool
and connected. Only then can the download be initiated.
Without group address 30/3/254 and a connection for the system time, the time
between the Synco bus devices after the first download can no longer be
synchronized.
If a different group address is used for the system time, this group address must be
entered and downloaded to all devices with system time communication (master
and all slaves).
It is not possible to set up group address 30/3/xxx (main group 30) in ETS with
default values. However, it is possible to enable the setting of main groups > 15 via
the Windows registry. Please address questions about the required entries for this
purpose to your ETS supplier.
The special group addresses can also be downloaded via the HIT Info Center ->
Product Overview -> Synco (www.siemens.com/hit) and imported in ETS.
