L-DALI User Manual 70 LOYTEC
Version 5.2 LOYTEC electronics GmbH
Figure 62: BACnet Access Control List (ACL).
The user can add and delete entries to the ACL. Each entry contains a source specification,
which consists of an IP address and an IP mask, and an action (allow or deny). For
specifying single hosts use the IP address and the mask '255.255.255.255'. For an address
range specify an appropriate mask. For example use '10.101.17.0' and the mask
'255.255.255.0' to specify all hosts with IP addresses '10.101.17.xxx'. To specify all IP
addresses use '0.0.0.0' and the mask '0.0.0.0'.
The ACL is evaluated from specific host entries down to wider ranges. When adding new
entries the ACL is automatically sorted, having the most precise definition at the top and the
most general one at the bottom. The default behavior is to allow packets from all IP
addresses. This is also the default entry in the ACL.
The example shown in Figure 62 specifies the following behavior for BACnet/IP:
1. Allow packets from the device 192.168.1.64
2. Otherwise allow packets from devices in the network 10.101.17.xxx
3. Otherwise deny packets from all (other) IP addresses. Note, that a "deny" overrules an
"allow".
5.2.17 Backup and Restore
A configuration backup of the L-DALI device can be downloaded via the Web interface.
Press the Backup/Restore link as shown in Figure 63 to start the download. The L-DALI
device assembles a single file including all required files. A file requestor dialog allows
specifying the location where the backup file shall be stored.
To restore the device settings, simply select a previously generated backup file in the
Restore Configuration section of the page by clicking the button next to the Filename
field. Then press the Restore button.
The backed up configuration data consists of:
Device settings (Passwords, IP settings, e-mail config, etc.),
Data point configuration and persistent values,
CEA-709 binding information,
AST settings,
Light and sunblind application parameters (incl. CLC Bindings),
DALI configuration,
Uploaded documentation and documentation links.
