In the other hand, can you also please advice how the "Data Log Open" ; "Data Log Close" ; "Data Log New File" work on your program ? Thanks & Regards |

Hello, I don't know the program you mentioned, but when you try to create a data log csv that already exists, the block "DataLogCreate" willreturn an error. In the following program there is a sequencer which reacts to such an error: http://support.automation.siemens.com/WW/view/en/64396156 |
