If the manual assignment of IP addresses is selected (instead of DHCP), the 4-byte
IP address can be programmed in ACS.
Other IP settings in ACS
• IP routing multicast address
• IP subnet mask
• IP standard gateway
When using the ETS3 engineering tool, e.g. in systems with third-party devices, the
ETS product database of Synco bus devices must be imported into ETS3.
Pay special attention to the following points when engineering with ETS3:
• ETS3 does not allow access to the LTE filter table (for filtering zone addresses).
• ETS3 does allow access to the S-mode filter table (for filtering group addresses).
• Fixed group addresses are defined in the KNX standard for some system
functions, including, for example, group address 30/3/254 for the system time.
• Group address 30/3/254 is set in the Synco bus devices before they leave the
factory.
When downloading new group addresses into Synco bus devices, the group
address 30/3/254 referred to above must be set up in the ETS3 tool and connected.
Only then can the download be initiated.
Without group address 30/3/254 and a connection for the system time, it will no
longer be possible to synchronize the time between the Synco bus devices after
the first download.
If a different group address is used for the system time, then 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 30/3/254 (main group 30) in the ETS3
with the default values. However, it is possible to enable the setting up of main
groups > 15 via the Windows Registry entries. Questions about the required entries
for this purpose should be addressed to your ETS3 supplier.
