Preface
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
2.1 Properties
● Supported control gear types and input device types:
– Fluorescent (control gear type 00)
– Emergency lamp (control gear type 01)
– Discharge lamp (control gear type 02)
– Halogen (control gear type 03)
– Incandescent (control gear type 04)
– Voltage converter (control gear type 05)
– LED (control gear type 06)
– Switch function (control gear type 07)
– Color control (control gear type 08)
– Push button (input device type 01)
– Absolute input device (input device type 02)
– Occupancy sensor (input device type 03)
– Light sensor (input device type 04)
– Other types by generic commands
● 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

3.1 Important notes on using the device
If the equipment is installed within an ultimate enclosure, the inner service temperature of
the enclosure corresponds to the ambient temperature of the module.
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.
Do not disconnect equipment unless power has been switched off or the area is known to
be non-hazardous.
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.
The equipment shall only be used in an area of not more than pollution degree 2.

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.

Enable or disable the diagnostic message on DALI bus.
• Enable: When the DALI bus is connected to a fault
over voltage (FOV) by mistake, the CM 1xDALI reports an error of over voltage and the FOV LED
(Page 109) is on.
• Disable: When the DALI bus is connected to a fault
over voltage by mistake, only the FOV LED is on.
Monitor the short circuit on DALI bus. This function is only
available when the integrated DALI bus power supply is
enabled:
• Enable: When a short circuit occurs on the DALI bus,
the module reports a diagnostic error and shuts down
the bus power.
• Disable: When a short circuit occurs on the DALI bus,
the module only shuts down the bus power.
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. As a result, the status that
is saved in CM 1xDALI cannot be updated in time to get
the latest status information in the CM 1xDALI. 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, con-
trol gear type and extended status
• For sensor: the information of device status, number
of instances and type of each instance

CM 1xDALI data storage model
CM 1xDALI data storage model
CM 1xDALI library is a SIMATIC CPU program library. You use the CM 1xDALI library to
program for the CM 1xDALI. It helps you easily access CM 1xDALI from the SIMATIC CPU.
CM 1xDALI library can be used on S7-1500 based CPUs (CPU 15xx).
CM 1xDALI library contains several CM 1xDALI function blocks (FB) in the STEP 7. The CM
1xDALI function blocks are collected in several functions groups, such as Addressing
function blocks (Page 32), Control gear dimming function blocks (Page 40), Diagnostic
function blocks (Page 52) and Configuration function blocks (Page 67).
Download the CM 1xDALI library from the Internet
(https://support.industry.siemens.com/cs/ww/en/view/109767048). For more information
about using libraries, refer to STEP 7 online help.
A DALI device can be a control gear or input device. The term "sensor" refers to the input
device in this documentation.
Each of the CM 1xDALI and DALI devices has its own database to store status and address
information.
The following figure shows the CM 1xDALI data storage model and data flow.

● The outputs of the FBs are kept when the processing of job is done:
– For the FBs with an input of CANCEL, only when both the trigger and input of
CANCEL turn to zero, their output is reset.
– For the FBs without the input CANCEL, when the trigger turns to zero, the output of
these FBs is reset.
● If the triggering input is reset before the FB has finished, the output parameters are set at
least for one cycle.
● The output of
the inputs ON_UP or OFF_DOWN; the output of this FB will not be reset all of the time.
● Most of the FBs have the following output parameters:
– BUSY: Shows whether the FB is being committed. When BUSY = 1, the FB is
triggered but not finished yet.
– ACTIVE: Shows whether the FB is being executed. When ACTIVE = 1, the FB is
communicating with the CM 1xDALI.
– DONE: Shows whether the FB is executed without errors. When DONE = 1, the FB is
executed without any error. You can check the result of execution in the output of this
FB.
– ERROR: Shows whether an error occurs during the process. When ERROR = 1, the
FB is stopped with some errors. You can check the error code in STATUS of this FB.
– STATUS: Shows the FB progress or detailed error code. When ERROR = 0, STATUS
shows the FB progress; when ERROR = 1, STATUS shows the detailed error code.
