Hello People, I am stuck trying to log messages to the USB stick. Using DL-06 PLC which changes a variable (16 bit word) that is used to index a "lookup text " object. When the message to be logged is indexed (the variable changes state) the message sometimes gets logged and can be copied to the USB as a line in a text file. Other times the message overwrites a previous message in the USB text file. The Automation Direct Tech said the messages would log to the USB automatically at midnight. That does not happen. Only by using a pushbutton with tag SYS_COPYLOGTOUSB can a message be copied to text file on the USB. Any Hints much appreciated

The EA9 has a buffer that gets filled as items are written to the USB stick. The buffer has to be emptied before pulling the sick out or the items are still left in the buffer.
That is why there are System Tags for Ejecting the USB stick. This causes the buffer to flush and the items to get written.
