Operator control unit for a field device used in automation technology

A generic communication driver for use in an operator control unit for a field device used in automation technology, the operator control unit having a first operating system, an application program executable on the first operating system and an emulation program configured to execute, on the application program, an application software which is executable on a second operating system, wherein the application system has at least one communication protocol for coding and/or decoding telegrams transmitted to and/or from the field device, wherein the application software is configured to read, display or modify parameters of the field device and/or read or display measured values of the field device, comprising:

• a DTM device driver or an FDI package executable in the application program for executing the emulation algorithm;
• wherein the operator control unit is a laptop, a workstation PC, or a tablet;
• wherein the operator control unit includes a communication interface for connecting the operator control unit to a wired or a wireless communication network, wherein the communication interface is accessible by the application software;
• wherein the first operating system is Microsoft Windows.
• wherein the second operating system is an operating system of a mobile terminal.
