FIELD DEVICE, COMMUNICATION CHIP, AND METHOD FOR A WEB ACCESS TO A FIELD DEVICE

The invention relates to a method for accessing a field device in order to simplify and/or improve web access to a field device. The field device is connected to a field bus designed for an Industrial Ethernet protocol or ProfiNET, and the method comprises transmitting a request from a web browser to a web server implemented in the field device, processing the received request in the field device by using a protocol stack of the Industrial Ethernet protocol, the protocol stack being stored in the field device, and transmitting response information from the web server to the web browser. The web server is implemented in the communication chip of the field device and both the communication with the controller and the web server use the same ProfiNET stack. The invention further relates to a field device designed to perform the method, and to a communication chip.
