Abstract
In connection with a method for the data exchange between an operating and monitoring program BA and a field device, which is connected via a field bus adapter with the internet, the operating and monitoring program BA accesses a serial interface, which is connected with an internet interface. By means of this a data exchange between the operating and monitoring program BA via the internet is possible without extensive program changes.
Claims10
A method for a data exchange between an operating and monitoring program BA which is running on a computing unit and a field device, comprising the steps of:
- connecting the field device to the internet via a field bus adapter;
- connecting the computing unit with the internet via an internet interface;
- providing a connection in the computer unit between the internet interface and a serial interface;
- and
- the operating and monitoring program BA accesses the serial interface in a customary manner thereby exchanging data between the field device and the operating and monitoring program BA over the internet.
A computer unit for exchanging data between an operating and monitoring program and a field device, comprising:
- an internet interface for connecting the computer unit with the field device via the internet and a fieldbus adapter;
- a serial interface which is accessed by the operating and monitoring program;
- and
- a connection between the serial interface and the internet interface for transferring data between the operating and monitoring program and the field device.
