Warning notice system
This manual contains notices you have to observe in order to ensure your personal safety, as well as to prevent
damage to property. The notices referring to your personal safety are highlighted in the manual by a safety alert
symbol, notices referring only to property damage have no safety alert symbol. These notices shown below are
graded according to the degree of danger.
DANGER
indicates that death or severe personal injury will result if proper precautions are not taken.
WARNING
indicates that death or severe personal injury may result if proper precautions are not taken.
CAUTION
indicates that minor personal injury can result if proper precautions are not taken.
NOTICE
indicates that property damage can result if proper precautions are not taken.
If more than one degree of danger is present, the warning notice representing the highest degree of danger will
be used. A notice warning of injury to persons with a safety alert symbol may also include a warning relating to
property damage.

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.

Feed visit (https://www.siemens.com/industrialsecurity).

Overview of system diagnostics

2.1 Properties of system diagnostics
Introduction
In the SIMATIC environment, the term "system diagnostics" refers to diagnostics of devices
and modules.
All SIMATIC products have integrated diagnostic functions that you can use to detect and
remedy faults. The components automatically flag a potential fault in the operation and
provide detailed information. You can minimize unscheduled standstill times with plant-wide
diagnostics.
The SIMATIC automation system monitors the following states in the running plant:
●Device failure/recovery
●Insert/remove event
●Module fault
●I/O access error
●Channel fault
●Parameter assignment error
●Failure of the external auxiliary voltage
Properties ofSIMATIC system diagnostics
●Integrated as standard in the hardware
●System-wide across bus limits
●Automatic localization of the error source
●Automatic output of the cause of the error in plain text
●Plant-wide diagnostics of all components
●Archiving and logging of alarms
●Configurability of alarms

Consistent diagnostics from the field level all the way to the management level
The various diagnostics media give you a uniform view of maintenance-related information of
every automation component in the plant: System status (module and network status, alarms
for system errors) are available plant-wide in a uniform display.

2.2 Benefits of innovative system diagnostics
System diagnostics is also possible in STOP
The system diagnostics is integrated in the firmware of the CPU and works independently of
the cyclic user program. This means it is also available in the STOP CPU operating mode.
Faults are detected immediately and signaled to the higher-level HMI devices, the Web
server and the display of the SIMATIC S7-1500 CPU, even in STOP mode. This makes
system diagnostics consistent with the actual plant state at all times.
Uniform display concept
All clients of a system are provided with diagnostics information by a uniform mechanism.
The same system diagnostics information is used regardless of the display medium.
Step
Description
①
The device detects an error and sends diagnostics data to the assigned CPU.
②
The CPU informs the connected display media. The display of the system diagnostics is
updated.
