METHOD FOR REPRODUCING THE SEQUENCE OF A PROGRAM IN AN AUTOMATION DEVICE
First Claim
1. A method for reproducing a sequence of a program provided for process control in an automation device, comprising:
- providing a backup program which corresponds to the program in the automation device with regard to process control for processing using a backup device;
utilizing the automation device to store an image in a backup memory at at least one predefined or predefinable time during process control, the image representing an internal state of the automation device at this time;
utilizing the automation device to store releases and process input values in the backup memory during the process control, the releases indicating which processing sections of the program have already been processed by the automation device;
utilizing the backup device to read the image as well as the releases and the process input values from the backup memory; and
utilizing the backup device to process processing sections of the backup program, which correspond to those processing sections of the program in the automation device which have already been processed, based on the releases and the process input values taking into account the image.
