- Page 2 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.
- Page 3 Preface Purpose of the documentation This function manual provides an overview of the PROFINET communication system with SIMATIC STEP 7 V13. STEP 7 V13 is integrated into the powerful graphical Totally Integrated Automation Portal (TIA Portal), the new integration platform for all automation software tools. This function manual supports you in planning a PROFINET system.
- Page 4 Siemens recommends strongly that you regularly check for product updates. For the secure operation of Siemens products and solutions, it is necessary to take suitable preventive action (e.g. cell protection concept) and integrate each component into a holistic, state-of-the-art industrial security concept.

- Page 17 Description 2.1 Introduction to PROFINET Transparent data access Access to process data from different levels of the factory is supported by PROFINET communication. By using Industrial Ethernet, standard mechanisms of communication and information technology such as OPC/XML can now be used along with standard protocols such as UDP/TCP/IP and HTTP in automation engineering.
- Page 18 Description 2.1 Introduction to PROFINET Update time The update time is a time interval. IO controller and IO device/I-device exchange IO data cyclically in the IO system within this time interval. The update time can be configured separately for each IO device and determines the interval at which output data is sent from the IO controller to the IO device (output module/submodule) as well as input data from the IO device to the IO controller (input module/submodule).
