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 visit (https://www.siemens.com/industrialsecurity).

TIA Selection Tool
With the TIA Selection Tool, you can select, configure and order devices for Totally Integrated
Automation (TIA).
This tool is the successor of the SIMATIC Selection Tool and combines the known
configurators for automation technology into one tool.
With the TIA Selection Tool, you can generate a complete order list from your product
selection or product configuration.
You can find the TIA Selection Tool on the Internet
(https://support.industry.siemens.com/cs/ww/en/view/109767888).
PRONETA
SIEMENS PRONETA (PROFINET network analysis) allows you to analyze the plant network
during commissioning. PRONETA has two core functions:
•The topology overview automatically scans the PROFINET and all connected components.
•The IO check is a fast test of the wiring and the module configuration of a plant.
You can find SIEMENS PRONETA on the Internet
(https://support.industry.siemens.com/cs/ww/en/view/67460624).
SIMATIC S7-PCT
The Port Configuration Tool ("PCT") is PC-based software for the parameter assignment of
Siemens IO-Link master-modules and IO-Link devices from any manufacturer.
The IO-Link devices are integrated using the standardized device description "IODD" that is
available from the respective device manufacturer. S7-PCT supports the version 1.0 as well as
V1.1 of the IODD.
S7-PCT is called via the hardware configuration of the IO-Link masters from STEP 7; however,
it can also be started as "standalone" if the IO-Link master is not operated on a SIMATIC
controller or when STEP 7 is not used.
You can find additional information on IO-Link on the Internet
(https://new.siemens.com/global/en/products/automation/industrial-communication/io-

4.4 IODD parameters
Device description IODD
An electronic device description is available for the DQ 8x24VDC/2A 8xM12 IO-Link digital
output module, the IODD file (IO Device Description). The IODD provides a wealth of
information for system integration:
•Communication properties
•Device parameters with value range and default value
•Identification, process and diagnostic data
•Device data
•Text description
•Image of the device
•Manufacturer logo
The structure of the IODD is identical for all devices from all manufacturers. The structure of
the IODD is always represented in the same manner by the IO-Link Configuration Tool of the
master manufacturer (for Siemens, S7-PCT). This ensures that the handling is the same for all
IO-Link devices regardless of the manufacturer.
IODDfinder
The IODDfinder is a cross-vendor, central IO-Link database.
This database provides you with the latest IODDs of the device manufacturers and offers an
information and download platform.
The IODDfinder is available on the Internet (https://ioddfinder.io-link.com).

5.2 Interrupts
The DQ 8x24VDC/2A 8xM12 IO-Link digital output module supports diagnostic interrupts.
Diagnostic interrupt
The digital output module generates a diagnostic interrupt at the following events:
•Short-circuit of outputs to ground
•Load voltage 2L+ missing or too low
5.3 Diagnostics alarms
For each diagnostic event, a diagnostics alarm is issued and the LED DIAG flashes red on the
digital output module. You can read out the diagnostics alarms, for example, from the status
of the IO-Link master. You can evaluate the error codes with the user program.
