Problems solved by technology

Due to the complex encryption and decryption of data telegrams with the required response times, the above known methods for securing communication can lead to signal failures or delays on the fieldbus
Delays or signal failures on the fieldbus often lead to downtime and associated production failures in plants operating with the fieldbus

Embodiment Construction

[0033] figure 1 A schematic chronological sequence of the transmitted data telegrams according to the invention is shown. exist figure 1 A communication system 7 , comprising a transmitter 1 and a receiver 2 , designed and arranged for carrying out the method according to the invention is shown. Both the transmitter 1 and the receiver 2 are identified as interrupted (dotted) rectangles and have a form which is usual in this context and which is not further described in this category.

[0034] The transmitter 1 comprises a processor or microcontroller 5 , a safety module or corresponding logic 8 and a fieldbus interface 10 . The receiver 2 comprises a processor or microcontroller 6 , a security module or corresponding logic 9 , a fieldbus interface 11 and a memory 4 . The two fieldbus interfaces 10 , 11 are connected to one another via the fieldbus 3 . The field bus 3 can be, for example, PROFIBUS, but is not limited thereto.

Abstract

A method for real-time-based transfer of data telegrams from a verified transmitter to a verified receiver without delays, wherein (a) each data telegram to be transferred from the transmitter to thereceiver is provided with an additional data index, (b) each received data is stored in a memory, along with the associated additional data index, (c) after elapse of a predetermined time interval, orafter transference of a defined number of data telegrams, the transmitter transfers a second time data telegram already transferred to the receiver which has an additional signature, and where the data telegram transferred the second time is additionally encrypted by the transmitter, and (d) after receiving the signed data telegram transferred the second time, the signed data telegram transferredthe second time is compared with the corresponding data telegram stored in the memory to verify the transmitter, and where (e) steps a) to d) are repeated.

Description

technical field [0001] The invention relates to a method for real-time transmission of a plurality of data telegrams from at least one transmitter to at least one receiver by means of a fieldbus in an industrial installation, in particular in an automation or process plant. Furthermore, the invention relates to a communication system and an industrial installation. Background technique [0002] In the context of industrial process, manufacturing and plant technology, fieldbuses are used which are based on conventional communication standards for communication between individual components of industrial installations. To ensure communication security when using these communication standards, various security measures should be implemented. [0003] On the one hand, communication participants participating in a fieldbus-based communication network must be authenticated as authentic. This is usually achieved through special signatures. [0004] On the other hand, data telegr...
