Method for assessing a use of a service and/or function provided or called by a web service (AK1;...; AK11), comprising the process steps: recognizing a web service call, recognizing information concerning the service and/or function provided or called by the web service (WS1; WS11), and assessing the use of the service and/or function provided or called, on the basis of parameters and the information captured, wherein the web service (WS1;...; WS 11) is implemented in an automation component (AK1;...; AK11) characterized in that the web service (WS1;...; WS11) implemented in the automation component (AK1;...; AK11) is called locally for the performance of the service and/or function by a web service call, in that the web service call or a function call generated by the web service (WS1;...; WS11) is locally recognized by means of a recognition module (ERKM1;...; ERKM11) implemented in the automation component (AK1;...; AK11), in that component-specific parameters (P, SLAG) are stored for the recognizing and capturing of web service calls in the form of service level agreements locally in a storage element of the automation components (AK1;...; AK11), in that service and/or function information concerning the called service and/or function and contained in the web service call or in the function call is locally read out by means of the recognition module (ERKM1;...; ERKM11) and locally stored in the storage element and compared to the stored capturing parameters, in that the web service (WS1;...; WS11) in the case of conformity of a recognition parameter is approved and performed by the recognition module (ERKM1;...; ERKM11), in that, during the performance of the web service (WS1;...; WS11), service and/or function-specific data is captured by means of a capturing module (ERFM1;...; ERFM11) locally implemented in the automation component, and stored in the storage module, and in that the service and/or function provided by the automation component (AK1;...; AK11) is(are) locally assessed on the basis of the service and/or function information, of the service- and/or function-specific data, and of the locally defined assessment parameters. recognizing a web service call, recognizing information concerning the service and/or function provided or called by the web service (WS1; WS11), and assessing the use of the service and/or function provided or called, on the basis of parameters and the information captured, wherein the web service (WS1;...; WS 11) is implemented in an automation component (AK1;...; AK11) characterized in that the web service (WS1;...; WS11) implemented in the automation component (AK1;...; AK11) is called locally for the performance of the service and/or function by a web service call, in that the web service call or a function call generated by the web service (WS1;...; WS11) is locally recognized by means of a recognition module (ERKM1;...; ERKM11) implemented in the automation component (AK1;...; AK11), in that component-specific parameters (P, SLAG) are stored for the recognizing and capturing of web service calls in the form of service level agreements locally in a storage element of the automation components (AK1;...; AK11), in that service and/or function information concerning the called service and/or function and contained in the web service call or in the function call is locally read out by means of the recognition module (ERKM1;...; ERKM11) and locally stored in the storage element and compared to the stored capturing parameters, in that the web service (WS1;...; WS11) in the case of conformity of a recognition parameter is approved and performed by the recognition module (ERKM1;...; ERKM11), in that, during the performance of the web service (WS1;...; WS11), service and/or function-specific data is captured by means of a capturing module (ERFM1;...; ERFM11) locally implemented in the automation component, and stored in the storage module, and in that the service and/or function provided by the automation component (AK1;...; AK11) is(are) locally assessed on the basis of the service and/or function information, of the service- and/or function-specific data, and of the locally defined assessment parameters.
