Hello Tony, 1. the parameter "HEADER" is hidden. It will be displayed when you click on the arrow in the buttom of the block. 2. chapter "Calculating the size of a data log file" (page 394) in http://support.automation.siemens.com/WW/view/en/91696622 Yes, you can delete the csv-file in the webserver only. Do you know this application? http://support.automation.siemens.com/WW/view/en/64396156 |

Hi Tony, "DataLogCreate.Status" = 16#7000 means "No job processing active." You must set the bit "DataLogCreate.REQ" to create the data log file (csv) on the webserver. Then ckeck if the data log file (csv) exists on the webserver by typing the IP address in your browser. The application (http://support.automation.siemens.com/WW/view/en/64396156) works. I upgrated it to V13 and updated the CPU to V3. Perhaps you have to delete the csv files on your webserver by resetting the CPU via "Online & diagnostics > Functions > Reset the CPU to factory settings" and download the project again. |
