In order to protect plants, systems, machines and networks against cyber threats, it is
necessary to implement – and continuously maintain – a holistic, state-of-the-art industrial
security concept. Siemens’ products and solutions constitute one element of such a concept.
Customers are responsible for preventing unauthorized access to their plants, systems,
machines and networks. Such systems, machines and components should only be
connected to an enterprise network or the internet if and to the extent such a connection is
necessary and only when appropriate security measures (e.g. firewalls and/or network
segmentation) are in place.
For additional information on industrial security measures that may be implemented, please
visit (https://www.siemens.com/industrialsecurity).
Siemens' products and solutions undergo continuous development to make them more
secure. Siemens strongly recommends that product updates are applied as soon as they are
available and that the latest product versions are used. Use of product versions that are no
longer supported, and failure to apply the latest updates may increase customers' exposure
to cyber threats.
To stay informed about product updates, subscribe to the Siemens Industrial Security RSS
Feed visit (https://www.siemens.com/industrialsecurity).

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
instance

General notices on use in hazardous areas according to FM
WARNING
Requirement for the installing enclosure
If the equipment is installed within an ultimate enclosure, the inner service temperature of
the enclosure corresponds to the ambient temperature of the module.
WARNING
Risk of burn injury
If a device is operated in an ambient temperature of more than 50 °C, the temperature of
the device housing may be higher than 70 °C. The device must therefore be installed so
that it is only accessible to service personnel or users that are aware of the reason for
restricted access and the required safety measures at an ambient temperature higher than
50 °C.
WARNING
Explosion hazard
Do not disconnect equipment unless power has been switched off or the area is known to
be non-hazardous.
WARNING
Cable
The equipment is intended to be installed within an enclosure/control cabinet. The inner
service temperature of the enclosure/control cabinet corresponds to the ambient
temperature of the module. Use cables with a maximum permitted operating temperature of
at least 30 °C higher than the maximum ambient temperature.
WARNING
Hazardous location
The equipment shall only be used in an area of not more than pollution degree 2.

DALI bus cable
Pay attention to the following requirements when you set up a DALI system.
Requirement for DALI cable
●The voltage drop between the DALI power supply and any DALI device on the DALI bus
must be less than 2 V.
●The cable length between DALI power supply and the DALI device should be less than
300 m. The recommend minimum-cross-section of the conductors depends on the cable
length.

Note
It is not necessary to use special bus cables (twisted or shielded).
Maximum current permitted for integrated DALI power
When use the integrated DALI power, the DALI bus load ∑ IDALI cannot exceeds 160 mA.
You can calculate the DALI bus load with the following formula:
∑ IDALI = IDALI_1 + IDALI_2 + IDALI_3 + ... + IDALI_n
∑ IDALI : Load of the DALI supply including all extension terminals
IDALI_1: Load of the first device on DALI bus
n: Total number of the devices on DALI bus
Example
You need to set up a DALI system with some control gears and sensors. At first, you add 64
control gears whose respective current consumption is 2 mA. Then you need to add a kind
of sensor whose respective current consumption is 5 mA.
The number of sensor you can add is:
(160 mA - 64 x 2 mA) / 5 mA = 6.4
So the maximum number of this kind sensor you can add in this DALI system is 6.

DALI bus topology
CM 1xDALI is a gateway between automation system and DALI system. At the CPU side,
CM 1xDALI works as a communication module and gateway to the system. At DALI side,
CM 1xDALI works as an application controller. You can use line, tree, star or mixed
structures to set up the DALI system.
NOTICE
Important notes on setting up DALI system
•Do not use ring structure to set up a DALI system.
•Use the input devices which fulfill the DALI-2 standard.
•CM 1xDALI module cannot work until CPU and IM are ready. Make sure CPUs are
ready before you start up the DALI communication.
The following figure shows an example of a DALI topology containing 4 DALI systems.
