8.4 USB File Transfer
The
“Utilities” section of the MCTB interface provides all the functionality required for retrieving files and
maintaining the internal SD memory card. The internal SD card should not be removed from the MCTB
interface. Any change to SD directory structure (moving or deleting files with a PC) may cause the MCTB
interface to stop operating and a new SD card will need to be ordered. Never move or delete the directories
unless using the provided MCTB file utilities functions.
NOTE: The data log files, programs, alarm log and audit trail directories are saved to the internal SD card
(not the USB memory stick device) plugged into the MCTB interface. Never unplug the SD card when
MCTB is powered up or loss of data may result.
The USB file transfer screen allows the user to copy or erase files from the internal SD card. Complete file
directories for all MCTB file types can be copied to the USB memory stick and erased from the internal SD card.
The current status for file functions is displayed for the operator during copy/delete operations. The MCTB also
allows automatic programs to be imported from the USB memory stick. Programs must be exported from
another MCTB device to the memory stick first, before this function can be used. The MCTB will look for
“Program” directories on the memory stick for import and alert the user if none exist.
NOTE: All file transfer functions can be used while data logging is running. If the operator needs to back up
or delete files from the system, a large number of files could take considerable time to backup and
delete from memory. The file transfer screen will be locked during file transfer so plan the timing
appropriately when access to other screen functions is not required.
When data logging is running, the current data log file will not be copied or deleted while using the
file transfer functions. This protects the current file and makes sure that the data file is complete
before being copied and cannot be deleted from memory while it is still in operation.
To
Copy files, insert the USB memory stick into the USB port. Select the file type you wish to copy from the
“Export Type” drop down menu. Available file selections are Program, Alarm, Audit and Data files. Once the
selection is made, press the “Copy” button. All related files will be copied to the USB memory stick with progress
status displayed to user.
To
Copy/Delete files from internal memory, insert the USB memory stick into the USB port. Select the file type
you wish to copy and erase from the MCTB internal
memory by selecting it from the “Export Type” drop down
menu. Available file selections are Program files, Alarm files, Audit trail files and Data files. Once the selection
is made, press the “Copy/Delete” button. All related files will be copied to the USB memory stick and then
deleted from the MCTB with progress status displayed to user.
