DALI Multi-Master module
753-647
The DALI Multi-Master module occupies a total of 24 bytes in the input and
output process image.
The DALI Multi-Master module can be operated in “Easy” mode (default) and
“Full” mode. "Easy" mode is used to transmit simply binary signals for lighting
control. Configuration or programming via DALI master module is unnecessary
in “Easy” mode.
Changes to individual bits of the process image are converted directly into DALI
commands for a pre-configured DALI network. 22 bytes of the 24-byte process
image can be used directly for switching of ECGs, groups or scenes in the Easy
mode. Switching commands are transmitted via DALI and group addresses, where
each DALI and each group address is represented by a 2-bit pair.
The structure of the process data is described in detail in the following tables.
