The Import file function allows automatic ramp/soak program files to be copied from the USB memory device
to the MCT. A dialog box will appear listing the available program directories on the USB memory stick.
Program directory names exported from the MCT are in the format
‘Profiles_mm-dd-yyyy-hh-mm-ss’.
NOTE: The USB memory stick must be inserted into the USB port for any of the file utility operations to function.
It is recommended to only use memory sticks certified by Future Design Controls for use with the MCT.
Future Design Controls has tested and validated these memory devices for proper operation and
performance.
Due to manufacturing variations in the USB memory sticks, it may take a few seconds up to 30 seconds
for the MCT to recognize the device when it is plugged in. Allow sufficient time for the device to be
recognized before attempting any file utility operations or the MCT will indicate a file transfer/memory
stick error.
When files are being copied to the USB storage device, a directory for each file type will be created to store the
copied files. The directory structure is as follows:
Program files directory: Profiles_mm-dd-yyyy-hh-mm-ss
Alarm files directory: Alarm Files_mm-dd-yyyy-hh-mm-ss
Audit files directory:
Audit Files_mm-dd-yyyy-hh-mm-ss
Data files directory Data Files_mm-dd-yyyy-hh-mm-ss
The purpose for using the date and time as part of the directory name, is to make sure the user can track the
date and time of the file transfer. If a user transfers a file type more than once in a single day, the files will be
grouped logically by time.
When accessing the data files saved to the USB memory stick, the data files will be in
“.csv” format. These
files can be opened directly with Microsoft Excel or any program that opens a comma separated file format.
You can copy or empty the
“Data Files”’ directory by simply plugging the USB device into a PC’s USB port. The
device then becomes like any removable disk attached to the computer and can be manipulated once plugged
into the PC.
The FDC Data Viewer program is a free Windows accessory program that allows users to view, plot and print
data files and is available from Future Design Controls or any manufacturer that markets the MCT product. It
is required when using the digital signature feature of MCT.
IMPORTANT: Once files are deleted from the MCT storage devices, they are gone and cannot be retrieved.
DO NOT edit, move or delete any other files from the internal SD memory card unless using
the MCT file utilities. The MCT will not operate properly if the file/directory structure is altered.
8.4.1 Recommended File Maintenance
A quick note about file storage; data and setup files (programs, data files, alarm log and audit trail files) need
some maintenance every now and then. After a period of time, storage devices fill up and files require backup
or file deletion when no longer needed. The Microsoft WinCE platform allows for a maximum of 999 files per
directory when all the files begin with the same 8 characters. Alarm and audit files are recorded by date (one
per day) with the format of MMDDYYYY (where MM = month, DD = day, YYYY = year) so there is essentially
no limit to the number of files other than available storage area.
Data log files however, could reach the maximum based on the number of files created per day and if the
logging on Program is enabled or a file name is specified by the user. If data logging is manually started or
activated on system Startup and only 1 file is created per day, there will be no effective file limit since the first
8 characters of the file name are the date, like that of alarm and audit files.
