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).

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).

Wiring and block diagram
This section includes the block diagram of the DI 8x24VAC/48VUC BA module with the
terminal assignments for a 1-wire and 2-wire connection.
Information about wiring of the BaseUnit is available in the system manual ET 200SP
distributed I/O system (http://support.automation.siemens.com/WW/view/en/58649293).
Note
You may use and combine the different wiring options for all channels.
Note
Hazardous voltage, risk of fatal or serious injury
Always disconnect the system and module from the power supply before c
ommencing work.
Note
Limiting overvoltage
You must ensure overvoltage is limited to 1
kV for the encoder supply.
Note
Power limitation
To limit power, each input voltage must have a fuse with a maximum rating of 10
A tripping
current. The fuse must
be a quick-acting microfuse.

Parameters
Parameters of DI 8x24VAC/48VUC BA
During configuration of the module with STEP 7, define the properties of the module via
various parameters. The following table lists the configurable parameters. The effective
range of the configurable parameters depends on the type of configuration.
The following configurations are possible:
●Central operation with an ET 200SP CPU
●Distributed operation on PROFINET IO in an ET 200SP system
●Distributed operation with PROFIBUS DP in an ET 200SP system
When performing the configuration in the user program, use the "WRREC" instruction to
transfer the parameters to the module using data records (refer to the section Parameter
assignment and structure of parameter data record (Page 24)).
The following parameter settings are possible:

Explanation of parameters
Diagnostics No supply voltage L
Enabling of the diagnostics for no or insufficient supply voltage L.
Channel activated
Determines whether a channel is enabled or disabled.
Potential group
A potential group consists of a group of directly adjacent I/O modules within an ET 200SP
station, which are supplied via a common supply voltage.
A potential group begins with a light-colored BaseUnit through which the required voltage is
supplied for all modules of the potential group. The light-colored BaseUnit interrupts the
three self-assembling voltage buses P1, P2 and AUX to the left neighbor.
All additional I/O modules of this potential group are plugged into dark-colored BaseUnits.
You take the potential of the self-assembling voltage buses P1, P2 and AUX from the left
neighbor.
A potential group ends with the dark-colored BaseUnit, which is followed by a light-colored
BaseUnit or server module in the station configuration.
