Am programing Unistream PLC model USP - 070-B10/B08. The program i need to make is User Logs with Data table. With UAC i add needed users also am making Data Table indexed and am writing the logs (log in or out ) into the data table. Also there is a possibility to enter in the HMI the batch number/lot that is later added to the Data Table depending on the user who is logged in at the moment. After that with a button on the hmi i set bit and Store DTI to file block is added. As i can see everything is good and this DTI block does not give me error. After i open the ftp server the SD CARD is empty. I chose in DTI file block to save it as .csv file format. I have no idea what might be happening. The sd card is 16 G card that i format FAT32.
