<p>The invention relates to a method for data exchange between an operating and monitoring program (BA) and a field device (10, 20, 30), connected to the internet by means of a field bus adapter (5). The operating and application program (BA) accesses a serial interface (8), connected to an internet interface (13). A data exchange between the operating and monitoring program (BA) via the internet is thus possible without significant program changes.</p> |
