DALI communication library
The current DALI standard does not guarantee a genuine multi-master function. Multi-master capable products such as those
of Tridonic, Osram or Zumtobel are either based on the new draft DALI extension E DIN 62386-103 (2011-08) or accept the loss
of telegrams in bus collisions. Permanent polling, e.g. of the status, should therefore be avoided in “multi-master” projects.
The maximum number of DALI master devices can be restricted to 8 units, for example, depending on the product and hard-
ware manufacturer.
Commissioning and servicing made easy
When initialising, the “DALI F26x Driver” FBox is positioned once only when the program starts.
The “Configuration Manager” FBox then parameterises all the DALI participants on the bus.
The FBox also provides predefined symbols for further use, e.g. in S-Web. The parameters can
also be used securely in the PCD file system. The “Backup to Flash” FBox stores all DALI para-
meters in parallel in two files. This guarantees the retention of data in PCD systems with no
batteries, e.g. in the Smart RIO PCD3.T666, required.
When commissioning DALI systems, it is usual to install all DALI participants then issue the ad-
dresses and set the parameters via the DALI commissioning software. The "Random addressing"
and "Exchange addresses" modules are in the Saia PG5® – DALI library.
Parameterisation takes place after the addressing process using the “Configuration manager”
FBox. Group and scene parameters can alternatively be set using the “Edit Groups” and “Edit
Scene Levels” FBoxes to provide a better overview.
Web visualisation for commissioning
Operation
The “Send Command Inputs”, “Send Command Online”, “Send Power Control” and “Send Scene”
FBoxes are available for transmitting DALI commands. These FBoxes cover all standard DALI
commands.
The receipt of master telegrams is also supported by the “Receive Commands” and “Receive Raw”
FBoxes. “Receive Raw” is useful for receiving non-standard telegrams. The raw data can then be
processed further in the application program.
The lamp status can be requested using the “Read Status” FBox. The “Query numeric” FBox pro-
vides the application program with access to a further 21 DALI standard data points such as the
current light level.
The “Read Memory” FBox is used to read any data from a DALI device. It is therefore possible to
request brightness and presence information from one sensor, which would not be accessible
with the DALI standard methods.

eration for this interface.
