Sorry!.. in fact this problem occurred several time after the installation of the System Automation for about 3 years now.

The Helpdesk people can't resolved the problem.. They proposes to change to a New Computer.

All that we know based on your information is that you have a system with an S7-1500 PLC and an Oracle database, and that on power loss the previous batch is not finished and 'data is lost'.
How the batch data is handled and how you send data from S7-1500 to the Oracle database, and where the data is lost is still a secret.

Is there a UPS? If not, add one.

My advice is to find someone who has knowledge on how the batch functionality is implemented in the S7-1500 and in the Oracle database, and how the two are interconnected. And then that person must investigate the problem.

Pay attention to the batch number.. when it goes down. Does it advance to the next one or jump back in sequence? It also may go to a specific number after a power failure which could indicate the PLC is restoring a program from onboard backup memory if it is configured to do so.
