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).
Open Source Software
Open-source software is used in the firmware of the I/O modules. Open Source Software is
provided free of charge. We are liable for the product described, including the open-source
software contained in it, pursuant to the conditions applicable to the product. Siemens
accepts no liability for the use of the open source software over and above the intended
program sequence, or for any faults caused by modifications to the software.

PRONETA
With SIEMENS PRONETA (PROFINET network analysis), you analyze the PROFINET
network during commissioning. PRONETA features two core functions:
●The topology overview independently scans PROFINET network 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).

Functions
2.2.1
Count
Introduction
As of firmware version V2.1.0 of the module you have the option of using channels 0 and 1
in the "Count" mode. The other channels can be used as standard inputs (DI mode).
If do not use channels 0 and 1 in the "Count" mode, these channels can also be used as
digital inputs. The two channels 0 and 1 can only be used as counter inputs together.
When counting, the edges of the digital input are acquired and evaluated accordingly e.g.:
●For counting single items up to a maximum limit
●For applications with repeating counting procedures
Reference
You will find the basics and additional information on the counting function in the function
manual Counting, measuring and position detection
(http://support.automation.siemens.com/WW/view/en/59709820).
Counting with channel 0 and channel 1
You control the counting function via the IO addresses of the module. These IO addresses
are also known as the control interface (output addresses) and feedback interface (input
addresses), see section AUTOHOTSPOT.
If you set the parameters of channels 0 and 1 for counting, you then have the following
options:
●You influence the behavior if one of the counting limits is exceeded using
–Stop counting.
–Continue counting.
●The bit STS_DQ (bit in the feedback interface) signals that the counted value is in one of
the following ranges depending on the parameter assignment:
–Between a comparison value and the high counting limit.
–Between a comparison value and the low counting limit.
●You can set a parameter for a hardware interrupt if a comparison event occurs for DQ.
●You can define counting limits and comparison values for counting from 0 ... 4294967295
(232-1).
●You can set start values or have the user program set load values for counting.
The count direction is only up.

You will find examples of counting with channels 0 and 1 in the section Examples of counting

Wiring

This section contains the block diagram of the module and outlines various wiring options.
You can find information on wiring the front connector, creating a cable shield, etc. in the
Wiring section of the S7-1500/ET 200MP
(http://support.automation.siemens.com/WW/view/en/59191792) system manual.
Wiring and block diagram
The figure below shows you how to wire the module and the assignment of the channels to
the addresses (input byte a to input byte b). You can set parameters so that channels 0 and
1 are used for counting. Channels 2 to 15 can continue to be used as digital inputs.

Manual, 08/2018, A5E03485952-AG 15
Resistor circuitry of the encoders
To detect a wire break, it is necessary that enough quiescent current is flowing even when
the encoder contacts are open. Connect a resistor of 25 kΩ to 45 kΩ with 0.25 W to the
encoder contacts for this reason.
Figure 3-2 Resistor circuitry of the encoders
Tip: Using the potential jumpers
Use the potential jumpers supplied with the front connector if you want to distribute the 24V
DC supply voltage to a neighboring module. This helps you to avoid having to terminate two
wires to one terminal.
Proceed as follows:
1. Connect the 24 V DC supply voltage to terminals 19 and 20.
2. Insert the potential jumpers between terminals 19 and 39 (L+) and between terminals 20
and 40 (M).
3. Use the terminals 39 and 40 to distribute the potential to the next module
Figure 3-3 Using the potential jumpers
Note
Ensure that the maximum current load of 8 A per potential jumper is not exceeded.

Parameters
DI 16x24VDC HF parameters
When you assign the module parameters in STEP 7, you use various parameters to specify
the module properties. The parameters that can be set depend on whether you use the
module in standard mode or in counter mode. You will find the parameters in section
Parameters DI mode (Page 17) or section Parameters of the Counting mode (Page 19). The
effective range of the configurable parameters depends on the type of configuration. The
following configurations are possible:
●Central operation with a S7-1500 CPU
●Distributed operation on PROFINET IO in an ET 200MP system
●Distributed operation on PROFIBUS DP in an ET 200MP system
For parameter assignment in the user program, the parameters are transferred to the
module using the WRREC instruction (parameter reassignment in RUN) and data records;
see chapter Parameter assignment and structure of the parameter data records (Page 45).
