Warning notice system
This manual contains notices you have to observe in order to ensure your personal safety, as well as to prevent
damage to property. The notices referring to your personal safety are highlighted in the manual by a safety alert
symbol, notices referring only to property damage have no safety alert symbol. These notices shown below are
graded according to the degree of danger.
DANGER
indicates that death or severe personal injury will result if proper precautions are not taken.
WARNING
indicates that death or severe personal injury may result if proper precautions are not taken.
CAUTION
indicates that minor personal injury can result if proper precautions are not taken.
NOTICE
indicates that property damage can result if proper precautions are not taken.
If more than one degree of danger is present, the warning notice representing the highest degree of danger will
be used. A notice warning of injury to persons with a safety alert symbol may also include a warning relating to
property damage.

Security information
Siemens provides products and solutions with industrial security functions that support the
secure operation of plants, systems, machines and networks.
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 under (https://www.siemens.com/industrialsecurity).

SIMATIC Automation Tool
You can use the SIMATIC Automation Tool to run commissioning and maintenance activities
simultaneously on various SIMATIC S7 stations as a bulk operation independently of the TIA
Portal.
The SIMATIC Automation Tool provides a multitude of functions:
●Scanning of a PROFINET/Ethernet network and identification of all connected CPUs
●Address assignment (IP, subnet, gateway) and station name (PROFINET device) to a
CPU
●Transfer of the data and the programming device/PC time converted to UTC time to the
module
●Program download to CPU
●Operating mode switchover RUN/STOP
●Localization of the CPU by means of LED flashing
●Reading out CPU error information
●Reading the CPU diagnostic buffer
●Reset to factory settings
●Updating the firmware of the CPU and connected modules
You can find the SIMATIC Automation Tool on the Internet
(https://support.industry.siemens.com/cs/ww/en/view/98161300).
PRONETA
With SIEMENS PRONETA (PROFINET network analysis), you analyze the plant network
during commissioning. PRONETA features two core functions:
●The topology overview independently scans PROFINET and all connected components.
●The IO check is a fast test of the wiring and the module configuration of a system.
You can find SIEMENS PRONETA on the Internet
(https://support.industry.siemens.com/cs/ww/en/view/67460624).

SINETPLAN
SINETPLAN, the Siemens Network Planner, supports you in planning automation systems
and networks based on PROFINET. The tool facilitates professional and predictive
dimensioning of your PROFINET installation as early as in the planning stage. In addition,
SINETPLAN supports you during network optimization and helps you to exploit network
resources optimally and to plan reserves. This helps to prevent problems in commissioning
or failures during productive operation even in advance of a planned operation. This
increases the availability of the production plant and helps improve operational safety.
The advantages at a glance
●Network optimization thanks to port-specific calculation of the network load
●Increased production availability thanks to online scan and verification of existing systems
●Transparency before commissioning through importing and simulation of existing STEP 7
projects
●Efficiency through securing existing investments in the long term and optimal exploitation
of resources
You can find SINETPLAN on the Internet (https://www.siemens.com/sinetplan).

●DQ 4×24VDC/2A HS MCC MtM (...)
Evaluating the value status
If you enable the value status function for the digital module, a byte in the input address
space is additionally assigned. Bits 0 to 3 of this byte are each assigned to one channel.
They provide information about the validity of the digital value.
●Bit = 1: No error is present on the channel.
●Bit = 0: Channel is disabled or there is an error in the module.
If an error occurs on a channel of this module, the value status for all channels is 0.

You can find information on wiring the BaseUnit in the ET 200SP distributed I/O system
(https://support.industry.siemens.com/cs/ww/en/view/58649293) system manual.
Note
You can connect 2 actuators per output.
Note
Cross circuit at output
Be aware that voltage from a cross circuit at the output can feed L+ to modules.
Note
•
The load group of the module must begin with a light BaseUnit. Keep this in mind also
during the configuration.
•
The connection of actuators with 1-wire connection is not permitted.
Note
You may use and combine the different wiring options for all channels.
Note
Outputs DQ
n- must not be connected with ground.
