CM 1xDALI Functionality
● CM 1xDALI controls the DALI bus and holds the parameters of the DALI devices. The
parameters are stored in the module even if power is off. The parameters can be read
from the CPU and deployed to the devices. There can be connected more than 64 sensor
instances in 1 DALI bus, but a maximum of 64 instance data sets can be stored in the
module.
● CM 1xDALI sends all received CPU commands from the CPU to the DALI bus, more
complex CPU commands (like setting parameters) are split into several DALI commands
by the module.
● CM 1xDALI has an operating hour counter for every device that can be read and set from
the CPU.
● If necessary, the module can scan the bus and assign short addresses to a newly
installed device on DALI bus with one command.
● CM 1xDALI queries the status of the devices cyclically, this action is called "background
detection". The CM 1xDALI periodically sends DALI commands to query the status of all
the devices on the bus and stores the information in the module. The query period can be
set by module parameters. The program blocks of the CPU have a higher priority when
accessing the DALI bus. If the program blocks of the CPU continuously access the DALI
bus, the background detection may be blocked. The background detection can detect the
following results:
– Whether each DALI device has a short address
– For control gear: the information of basic status, control gear type and extended status
– For sensor: the information of device status, number of instances and type of each
