Abstract
In a method for testing device descriptions for field devices of automation technology, a finite state machine is produced from a device description to serve as a basis for a test script. For testing the device description, the test script is executed, with data being sent to and received from the device description. In such case, it is tested whether desired values set in the test script agree with actual values delivered e.g. from the field device.

A method for testing device descriptions for field devices of automation technology, wherein the device descriptions are integrated into an operating program for servicing field devices, comprising the steps of:
- producing a finite state machine from a device description based on states and state transitions;
- producing a test script with help of the finite state machine;
- executing the test script, wherein data are sent to and received from the device description, for generating actual values;
- and
- comparing desired values predetermined by the test script with the actual values.
