  • Method for modifying a configuration and industrial plant system
    Patent number: 11307552
    Abstract: In order to enable a seamless configuration modification during operation, a first automation device sends a second automation device a request for parameter modification. The second automation device responds to the request, such that a standby acknowledgement of the request is sent. Immediately with the transmission of the standby acknowledgement in the second automation device, an output process image is frozen, and the modification of the communication parameters for the second automation device is carried out. The first automation device responds, such that after receiving the standby acknowledgement in the first automation device, the communication is immediately stopped and the modification of the communication parameters is carried out for the first automation device. An input process image is frozen.
