Initially it worked fine, but recently these logs are not logging properly. Some files have all the data, some stopped in the middle and some have no data at all............any idea why?

Currently i have 10 Datalogs, total 34 tags, and all these are set for "Segmented Circular logs". some of these tags work just fine, and some don't. I am saving these tags in .csv format on USB. The Datalogs are set for 20000 records per log and Number of Logs are 20. See attached jpg showing datalog setup. any idea why some tags would work fine and won't?

Tweety Posts: 3037 Rating: (190)	Hello, Which panel do you use? You have written you use a MP370. The USB stickwasnot tested and released for MP370. See file “ HMI_Panels_Slots.pdf the following FAQ. Which external storage media can you use with the SIMATIC panels and which memory card interfaces do they have? You should use a PC-Card or CF-Card for logging. Tweety
