Method and controller for controlling a safety-oriented industrial automation component

摘要

A method for a safety-oriented industrial automation component, wherein the controller is connected to the automation component by a data link includes providing, by a user, an input to the controller at a first user interface. The controller transmits a result of the input to the automation component. The result of the input is used in the automation component to calculate a first test value. The input is converted into a status display in the controller and is output at a second user interface. Here, the user or another user acknowledges the status display by inputting a confirmation, after which a second test value is formed from the status display and the confirmation in the controller, and the second test value is transmitted to the automation component. Finally, the first and second test values are compared in the automation component and the result of the input is used if the comparison is positive.

1. A method for controlling a safety-oriented industrial automation component arranged in an industrial automation arrangement with a controller which is connected by a data link to the safety-oriented industrial automation component arranged in the industrial automation arrangement, the method comprising:
acquiring a user input by the controller at a first user interface, and transmitting from the controller a result of the input to the safety-oriented industrial automation component arranged in the industrial automation arrangement, the safety-oriented industrial component comprising a parameter list associated with a failsafe program; calculating, in the safety-oriented industrial automation component arranged in the industrial automation arrangement, a first test value based on the result of the input; converting, in the controller, the input into a status display and outputting the status display at a second user interface, said converting comprising transmitting the result of the input, which is transmitted to the safety-oriented industrial automation component arranged in the industrial automation arrangement, back to the controller from the safety-oriented industrial automation component, and converting the result of the input into the status display; inputting, at the second interface, a confirmation comprising a graphical user event to acknowledge acceptance of the status display; forming, in the controller, a second test value from the status display and the confirmation indicating acceptance of the status display; transmitting from the controller the second test value to the safety-oriented industrial component; and comparing, at the safety-oriented industrial automation component arranged in the industrial automation arrangement, the first and second test values, and when the comparison is positive, accepting the result into the parameter list and subsequently using the result.
