摘要

The system has a program unit (2) that stores a program, and an input unit (3) for changing a parameter that is stored in an online-memory (4). An offline-data file serves for cyclic writing of the parameters selected from the memory. A restore function in the program is activated based on predetermined criteria and loads parameter that is stored in an external file (5) in to the memory for operation of the program.
