FAQ  06/2016 Modbus/TCP with WinAC RTX (F) in TIA Portal V13 SP1 WinAC RTX, Modbus TCP https://support.industry.siemens.com/cs/ww/en/view/109482560

d e v r e s e r s t h g i r l l A 6 1 0 2 G A s n e m e S  i Security informa- tion This entry is from the Siemens Industry Online Support. The general terms of use (http://www.siemens.com/terms_of_use) apply. 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 only form one element of such a concept. Customer is responsible to prevent unauthorized access to its plants, systems, machines and networks. Systems, machines and components should only be connected to the enterprise network or the internet if and to the extent necessary and with appropriate security measures (e.g. use of firewalls and network segmentation) in place. Additionally, Siemens’ guidance on appropriate security measures should be taken into account. For more information about industrial security, please visit http://www.siemens.com/industrialsecurity. Siemens’ products and solutions undergo continuous development to make them more secure. Siemens strongly recommends to apply product updates as soon as available and to always use the latest product versions. Use of product versions that are no longer supported, and failure to apply latest updates may increase customer’s exposure to cyber threats. To stay informed about product updates, subscribe to the Siemens Industrial Security RSS Feed under http://www.siemens.com/industrialsecurity.

1 Introduction 1.1 Overview 1 Introduction 1.1 Overview These FAQs will provide you with a step-by-step instruction on how to configure the SIMATIC Modbus/TCP software under a WinAC RTX (F) Software PLC with TIA Portal V13 SP1. Figure 1-1 d e v r e s e r s t Note This description only refers to the configuration of the SIMATIC Modbus/TCP software under WinAC RTX (F) in the TIA Portal V13 SP1. For detailed information on Modbus/TCP, WinAC RTX (F) or the TIA Portal, refer to the corresponding documentation. h g i r l l i A 6 1 0 2 G A s n e m e S  SIMATIC WinAC RTX (F) SIMATIC WinAC RTX (F) is the SIMATIC software controller for PC-based automation solutions and allows real-time deterministic control on the PC. SIEMENS Modbus/TCP software MODBUS is a worldwide communication protocol which is open to all users and is used by many manufacturers. On this basis, MODBUS/TCP has been developed for the use in modern networks. In today’s industry, this protocol has become a de facto standard which has been introduced in the Internet Engineering Task Force (IETF) – an organization responsible for Internet standardization. The SIMATIC Modbus/TCP software packages offer ready-to-use blocks for simple and quick implementation of a MODBUS communication in SIMATIC controllers.
