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).

SIMATIC Automation Tool
You can use the SIMATIC Automation Tool to perform commissioning and maintenance
activities simultaneously on various SIMATIC S7 stations as a bulk operation independent of
TIA Portal.
The SIMATIC Automation Tool provides a multitude of functions:
•Scanning of a PROFINET/Ethernet system network and identification of all connected CPUs
•Address assignment (IP, subnet, gateway) and station name (PROFINET device) to a CPU
•Transfer of the date and the PG/PC time converted to UTC time to the module
•Program download to CPU
•RUN/STOP mode switchover
•CPU localization by means of LED flashing
•Reading out of CPU error information
•Reading the CPU diagnostics buffer
•Reset to factory settings
•Firmware update of the CPU and connected modules
You can find the SIMATIC Automation Tool on the Internet
(https://support.industry.siemens.com/cs/ww/en/view/98161300).
PRONETA
SIEMENS PRONETA (PROFINET network analysis) allows you to analyze the plant network
during commissioning. PRONETA features two core functions:

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 the optimal use of
resources

18 Equipment Manual, 06/2021, A5E46570510-AB
4.2 Explanation of the parameters
Diagnostics: Undervoltage 1L+
Enabling of diagnostics for insufficient supply voltage 1L+.
Undervoltage at 1L+ triggers the "Undervoltage" maintenance event. You can find more
information in section Maintenance events (Page 28).
Diagnostics: Short-circuit
Enabling of diagnostics for short-circuit to ground at transducer supply
Diagnostics: Wire break detection and alarm
Activation of wire break detection and enabling of diagnostics. In the event of an interruption
of the line between the encoder and I/O device, a diagnostics alarm is generated.
Note
Effect on the value status
When the parameter is deactivated, wire break detection is switched off. A wire break does
not have an effect on the value status.
Input delay
This parameter can be used to suppress signal interference. Changes to the signal are only
detected if they are present consistently for longer than the set input delay time.
In isochronous mode, the terminal signal is read in at the time Ti(time for reading the input
data). The read-in time T relates to the channel for which an input delay time of 0.05 ms was
configured.
For input channels with longer input delays, the read-in time is moved accordingly. This
means individual channels can be assigned input delays, if necessary, without having a
negative impact on the possible cycle time.
Isochronous configuration is only possible if there an input delay of 0.05 ms is configured for
at least one channel. Otherwise, the "Parameter assignment error" diagnostics alarm is
output.
Hardware interrupt on rising edge
Specifies whether a hardware interrupt is generated for a rising edge on the channel.
Hardware interrupt on falling edge
Specifies whether a hardware interrupt is generated for a falling edge on the channel.
