Chapter 2. CPU Features & Specifications
Uploading a Project from the CPU to the RDSD
Notes: Only one application project can be stored to the RDSD at a time. Before the RX3i writes the
project to the RDSD, any previous application is removed; if a directory named PACS_Folder
exists on the RDSD at the start of the upload, it is deleted with all of its contents.
Flash devices write in whole memory blocks and memory block sizes vary among devices. The
amount of space used by a project may vary between RDSDs due to the differences in minimum
block sizes and therefore the number of blocks used by a project. The minimum amount of
memory required will be the size of the entire project plus an additional block for the options.txt
file, if used.
1. Place the CPU that contains the project to be transferred in RUN Mode or STOP Mode.
2. If PME is online with the RX3i, either go Offline or select Monitor mode.
3. Insert the RDSD into the USB connector on the CPU. (After 1 – 2 seconds, the RDSD LED turns solid
green.)
4. For CPE302/CPE305/CPE310, push the RDSD direction switch to the left (UPLOAD), then
momentarily depress the START pushbutton. For CPE330, depress the RDSD UPLD pushbutton.
5. Do not remove the RDSD from the CPU during the transfer.
The RDSD LED blinks green during the transfer. This can take from 10 – 150 seconds, depending
▪
upon the size of the project data.
The RDSD LED should turn solid green, indicating that the transfer completed successfully.
▪
If the RDSD LED turns solid red, the transfer has failed. There will be a copy of the fault tables as
▪
they existed at the end of the attempted transfer on the RDSD. Insert the RDSD into a PC which
has the PACS Analyzer software and select the plcfaultafter.dat file on the RDSD for fault table
analysis by the Analyzer. The PACS Analyzer software can be downloaded from the Support
website, www.geautomation.com.
If the RDSD LED turns solid red, indicating an error, another RDSD operation cannot be initiated
▪
until the device is disconnected then reconnected.
▪
▪
6. When the RDSD LED turns solid green, indicating the transfer has been successfully completed,
remove the RDSD from the CPU. The RDSD can now be used to transfer the application to other RX3i
controllers of the same model type.
You can copy the entire applications directory to another USB device and use that device as the
source for downloads to CPE302/CPE305/CPE310/CPE330 CPUs, provided none of the files in that
directory are changed in any way during the transfer.
24
If the RDSD is removed during data transfer from the CPU, the
integrity of the RDSD and the files on it cannot be guaranteed. The
RDSD status LED may indicate an RDSD fault, and the CPU will
abort the data transfer and remain in its current operating mode.
The project files, consisting of the entire contents of the PACS_Folder
directory and all of its subdirectories, loaded on the RDSD must not be
modified. If they are modified, the files transferred to the CPU will be
invalid.
