4.14 Transferring project data using a USB memory stick
The CECC supports reading in project data via the USB interface.
Prerequisites for transferring a project from a USB memory stick without any errors.
– Firmware version 1.3.4.0 or later
– USB memory stick is formatted: file system FAT or FAT32 only
– CECC used is selected: CECC-D, CECC-LK or CECC-S
– "Device Description in Project" and "CECC Runtime System" versions are the same ( Version
information)
– "Load Project Data from USB Memory" function in the USB configuration of the CECC is activated (=
default setting PLC shell commands: "usbsetconfig" and "usbgetconfig")
– CECC is switched off
Note
Existing project data on the CECC is deleted before a project is transferred from a USB memory
stick.
• Make sure that the current data on the CECC is available in a Codesys project and can be
used for recovery in the event of errors.
To generate USB project data:
1. Plug a USB memory stick into your PC.
2. Open the project to be saved on the USB memory stick. (Click the program in the "PLC logic" branch
of the CECC in the device window.)
3. Select the command [Online] [Create USB files].
4. Switch to the drive letter for the USB memory stick.
5. Start saving to the USB memory stick by clicking "OK".
6. If necessary remove the USB memory stick and unplug it from the PC.
To transfer the project from a USB memory stick to a CECC:
1. Plug the USB memory stick into your CECC.
2. Switch on the CECC.
The CECC detects the project data on the USB memory stick and uploads it to the flash memory (non-
volatile memory) of the CECC. The uploaded project is then automatically started.
3. Remove the USB memory stick so that this process is not repeated the next time the CECC is
switched on.
