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.

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
Pulse-width modulation (PWM)
Channels 0 and 4 of the module support the pulse width modulation (PWM) function. The
pulse width modulation function can be used to easily generate periodic pulses with a
constant rated voltage and a variable pulse duration for the above-mentioned channels.
Advantages
●Automatic generation of periodic signals (without user program).
●Possibility of power reduction, e.g. in solenoid valves.
Typical areas of application:
●Control of proportional valves and way values (e.g. energy saving by reducing the holding
current).
●Heating control e.g. via an external additional power unit.
Requirement
Firmware version as of V2.1.0 of the module.
Rules
Channels 0 and 4 can be used together and individually in pulse width modulation mode.
The remaining channels can continue to be used as digital outputs.
Configuration
You configure the pulse width modulation with the following parameters:
●Pulse width modulation mode for activating the function
●Pulse width modulation (time period)

14 Manual, 06/2018, A5E03485650-AF
How it works
In the pulse width modulation mode, the two outputs (channels 0 and 4) provide one pulse
width modulated output signal.
Pulse width modulation is characterized by its time period (frequency) and its duty factor
(also referred to as ON period or Duty Cycle ). The duty factor describes the relation
between pulse duration and time period.
The pulse duration is derived from the time period and the duty factor: Pulse duration = duty
factor x time period.
Example for duty factor of 50% and time period of 10 ms:
Pulse duration 0.5 x 10 ms = 5 ms
You define the duty factor for channels 0 and 4 in the user program using the output value
(0 ... 1000) in the process image output; see section Address space operating mode pulse-
width modulation (Page 29).
The output signal is a square wave signal (pulse sequence of on and off pulses).
①
Time period T (2 to 100 ms); Frequency of the pulse width modulation: f = 1/T (10 to 500 Hz)
②
Pulse duration (duty factor x time period)
Figure 2-2 How pulse width modulation works
Minimum pulse duration
The minimum pulse duration is 300 μs due to the hardware. The duty factor can be adjusted
from 0.0 to 100.0%. The time period can be adjusted from 2 to 100 ms.
Example: If you configure a time period of 2 ms and set a duty factor of 10% for the output,
this results in a pulse duration of 200 μs. In fact, the output works with a minimum pulse
duration of 300 μs.

16 Manual, 06/2018, A5E03485650-AF
Example for energy saving by reducing the holding current
High starting current is required to activate a solenoid valve. When the solenoid valve is
activated, the current requirement is lower; it only has to be held in position. This time-
dependent current requirement can be met well with the PWM function.
The "ValveControl" function block shown below sets the holding current required by a
solenoid valve only after the configured time (HoldTime) has expired. You can generate the
required holding current with a duty factor (PWM duty cycle << 100%). While "HoldTime" is
running, the output is set (duty factor = 100 %) to generate a high starting torque for the
solenoid valve.

2.2.2
Switching cycle counter
The function records the number of switching cycles of the output and thus the switching
cycles of a connected actuator, such as those of solenoid valves. When the specified
number of switching cycles is reached, the "Limit value warning" maintenance interrupt is
triggered, provided it is configured and enabled. When replacing the actuator, you can reset
the switching cycle counter from the user program.
When replacing modules, you have the option of pre-initializing the switching cycle counter
from the user program.
Typical areas of application:
●Recording the number of switching cycles of the connected devices, e.g. solenoid valves
or load contactors
●Predictive maintenance
Advantages
●You configure this function instead of programming.
●"Monitoring" of each individual channel is possible. You can select which outputs are
"monitored".
●You can adapt the plant configuration flexibly and individually.
●Easy to service and maintain. You can enable and disable the switching cycle counter via
the user program.
●Increase in plant availability. You can schedule actuator replacement in advance for the
next maintenance cycle.
Requirement
Firmware version as of V2.2.0 of the module.
Configuration
You configure the switching cycle counter with the following parameters:
●Switching cycle counter enabled/disabled
●Trigger maintenance interrupt when the limit is reached
●Set limit for maintenance interrupt

DQ 8x24VDC/2A HF Digital Output Module (6ES7522-1BF00-0AB0)
18 Manual, 06/2018, A5E03485650-AF
How it works
The module counts the switching cycles by evaluating the rising edges of an output signal. If
the module detects a rising edge, the switching cycle counter (24-bit) for the respective
channel is incremented. After an overflow of the switching cycle counter, it starts again with
0.
If you activate the "Maintenance switching cycles" parameter, the "Limit warning" of the
maintenance interrupt is triggered when the limit is exceeded. Alternatively, activate the
maintenance interrupt in the parameter data sets starting at DS 64.
The current counter states are stored on the module cyclically (approx. every 20 seconds)
and retentively. The switching cycle counters are reset each time the module is restarted
(power off/on).
You activate the function with the "Switching cycle counter" parameter or in the parameter
data sets starting at DS 64.
You can read the current counter states with data set DS 129. Data set DS 129 contains the
counter status for each channel in UDINT format.
You can read the limits for each channel in UDINT format with data set DS 130.
Data set DS 131 enables you to overwrite the current counter value for each switching cycle
counter.
You can set a limit for each switching cycle counter with the "Switching cycle limit" parameter
or with data set DS 131.
