Hi, What do you mean by saying "loose values". When ? After restart ? Keep in mind that by default data in DB are not retentive. You must check option for retentivity. Also please upgrade firmware of PLC because it has some issues with DB data. Look here http://support.automation.siemens.com/WW/view/en/34612486/133100 and choose appropriate PLC. |
Best regards, |
