Problems solved by technology

[0008] However, during initial operation and repeated start-up of the control and data transfer system, it cannot be reliably tested whether the safety component is actually connected to the desired installation location of the control and data transfer system without using address translation of the safety component

Embodiment Construction

[0039] Figure 1 shows in a schematic block diagram a control and data transmission system designated as 10 as a whole, in which bus components are connected to each other in a ring. In this example, the control and data transmission system 10 is an Interbus transmission system implementing the present invention. For example, the Interbus transmission system is described in the reference book "Interbus-S: Grundlagen und Praxis [Interbus-S: Fundamentals and Practice]" written by A. Baginski of Hüthig Buchverlag GmbH in Heidelberg in 1994.

[0040] The Interbus transmission system 10 shown in FIG. 1 includes a bus component 30 used as a non-safety communication control device, and is hereinafter referred to as the Interbus master device for short. The Interbus master device 30 is connected to the field bus 70 of the Interbus transmission system 10 and is connected to the safety control device 50 via a coupling memory 40, for example. The safety control device 50 is a device having a ...

Abstract

The invention relates to a method and to a control and data transmission system which can verify the installation location of at least one secure bus component that is connected to the control and data transmission system (10). To achieve this, a respective location identifier, which has been assigned to the secure bus components (60) in a previous configuration process, is transmitted in two separate communication cycles to the respective secure bus components via a non-secure communications control unit (30). The secure bus components compare the location identifiers received in the two communication cycles with the contents of a memory, in which a reference location identifier has already been stored, or which is still empty. A comparison of the transmitted location identifier, the reference location identifier and the configuration data record that is stored in a secure control unit (50) allows a verification to be made as to whether the respective secure bus component is connected at the predetermined installation location in the control and data transmission system (10).

Description

Technical field [0001] The present invention relates to a method for checking the installation location of at least one secure communication component connected to a control and data transmission system, and a control and data transmission system particularly suitable for carrying out the method. Background technique [0002] Nowadays, control and data transmission systems occupy a prominent position in industrial production and factory control due to the high degree of automation possible. The communication system is very widely used. Through the use of the communication system, many decentralized input and output units are connected to the central control device. [0003] In order to ensure safety standards in the execution of safety-critical processing, communication systems mainly used in automation technology include, for example, CAN bus, profibus or INTERBUS connected to safety-oriented bus components. Safety-oriented processing includes, for example, monitoring of protect...
