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 can 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).

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).

Wire-break detection
When wire-break detection is configured the module requires a low quiescent current at the
digital input in case of "0" signal for the monitoring. The parallel connection of a resistor with
25 kΩto 45 kΩis required in order that this quiescent current can flow when mechanical
transducer contacts are open.
If wire-break detection is disabled in the configuration, no parallel connection of the resistor
is required.
If wire-break detection is configured, connect a resistor with 25 kΩto 45 kΩparallel to each
mechanical transducer contact.

4.1 Parameters
Parameters for DI 8x24VDC ST
Specify the module properties with the various parameters in the course of your STEP 7
configuration. The following table lists the configurable parameters. The effective range of
the 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 assigning parameters in the user program, use the "WRREC" instruction to transfer
the parameters to the module using the data records; refer to the section Parameter
assignment and structure of the parameter data record (Page 27).

Due to the limited number of parameters of a maximum of 244 bytes per ET 200SP station with a PROFIBUS GSD
configuration, the parameter assignment options are restricted. The parameter length of the I/O module is 3 bytes with
PROFIBUS GSD configuration. If necessary, you can set this parameter by using the data record 128, see the appendix
"Parameter data record".

18 Manual, 02/2019, A5E03574157-AF
4.2 Explanation of the parameters
Diagnostics no supply voltage L+
Enabling of the diagnostics for no or insufficient supply voltage L+.
Diagnostics short-circuit to ground
Enabling of the diagnostics if a short-circuit of the encoder supply to ground occurs.
Diagnostics wire break
Enabling of the diagnostics if the module has no current flow or the current is too weak to be
measured at the relevant input.
Channel activated
Determines whether a channel is enabled or disabled.
Input delay
This parameter can be used to avoid signal faults. Changes to the signal are only detected if
they are constantly pending longer than the set input delay time.
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 follows a light-colored
BaseUnit or server module in the station configuration.

The module can be configured differently in STEP 7; see following table. Depending on the
configuration, additional/different addresses are assigned in the process image of the inputs.
Configuration options of DI 8x24VDC ST
You can configure the module with STEP 7 (TIA Portal) or with a GSD file. If you configure
the module using a GSD file, the configurations are available under various short
designations/module names; see the table below. The following configurations are possible:

Evaluating the value status
An additional byte is allocated in the input address space if you enable the value status for
the digital module. Bits 0 to 7 in this byte are assigned to a channel. They provide
information about the validity of the digital value.
Bit = 1: No fault is present on the channel.
Bit = 0: Channel is disabled or there is a fault/error on the module.
If a fault/error occurs on a channel with this module, the value status for all channels is 0.
Address space
The following figure shows the assignment of the address space for the DI 8×24VDC ST with
value status (Quality Information (QI)). The addresses for the value status are only available
if the value status is enabled.
