System for testing the functioning of program controlled components of complex equipment or plant, whereby test command sequences can be recorded in a test script which can be used at a later time to simply reproduce the test

摘要

System for testing the functioning of one or more software based control components of a machine or plant, whereby the control component (1) controls one or more sub-components. The system comprises a computer (6) that communicates with the control component and has input means (7, 8) for input of test commands as well as a memory (14) for automatic storage of input test commands in the form of a software based test script, that can be recalled later for automatic repeat or new testing.
