Screenshot via HTTP Request

If, for example, decisions are made on the shop floor on the basis of a visualization, it is necessary to document the decision basis. This can be done, for example, by taking a screenshot of the visualization.

This command looks like this:

HTTP Get Request

The request URL is as follows, where GET is used as the method:

[Box name]:8080/api/iot/screenshot

If the request is successful, you receive a screenshot of the current display for further processing from the box.
