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.

Qualified Personnel

The product/system described in this documentation may be operated only by

personnel qualified

for the specific

task in accordance with the relevant documentation, in particular its warning notices and safety instructions.

Qualified personnel are those who, based on their training and experience, are capable of identifying risks and

avoiding potential hazards when working with these products/systems.

Note the following:

WARNING

Siemens products may only be used for the applications described in the catalog and in the relevant technical

documentation. If products and components from other manufacturers are used, these must be recommended

or approved by Siemens. Proper transport, storage, installation, assembly, commissioning, operation and

maintenance are required to ensure that the products operate safely and without any problems. The permissible

ambient conditions must be complied with. The information in the relevant documentation must be observed.

Preface

Purpose of the documentation

The controller offers various options for program execution with different run priorities.

Cyclic-driven and time-driven program execution have the largest share. The response times

of a controller are therefore significantly determined by the processing cycles.

There is also the possibility of event-driven program execution. The event-driven program

execution is normally limited to a few selected events.

This manual provides information on the following topics:

●Types of program execution

●Run priorities

●Cycle and response times, and the influences to which they are subject

●Configuration options for the optimization of your user program

Basic knowledge required

The following knowledge is required in order to understand the documentation:

●General knowledge of automation technology

●Knowledge of the SIMATIC industrial automation system

●Knowledge of the use of Windows-based computers

●Knowledge of working with STEP 7

Conventions

STEP 7: In this documentation, "STEP 7" is used as a synonym for all versions of the

configuration and programming software "STEP 7 (TIA Portal)".

Please also observe notes marked as follows:

Note

A note contains important information on the product described in the documentation, on the

handling of the product or on the section of the documentation to which particular attention

should be paid.

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).
