GE IS200SRLYS1A, S2A 12 Form C mechanical relays-dry contacts
Note: When using RDSD, all programming software connections must be in the Offline state for theRDSD to function properly.
Note: CPE330 does not support Cfast memory cards as RDSD devices.
2.1.8.1 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 sec, the RDSD LED turns solid
green.)
4. For 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 sec, 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.
Caution
▪ 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.

You can copy the entire applications directory to another USB device and use that device as the
source for downloads to CPE305/CPE310/CPE330 CPUs, provided none of the files in that
directory are changed in any way during the transfer.
2.1.8.2 Downloading a Project from the RDSD to the CPU
To download a project to the RX3i, the RDSD must contain a valid project, consisting of the hardware
configuration, application logic, and reference memory in a compiled format (originating from
another RX3i controller). 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.
By default, all project components are stored to the CPU and are written to flash. You can change
this operation by placing an options.txt file on the RDSD as described below.
1. Ensure that the RX3i is in STOP Mode
2. If PROFICY Machine Edition is online with the RX3i, either go Offline or select Monitor mode.
3. Connect the RDSD to the USB connector on the CPU that will be receiving the files. The RDSD LED
turns solid green.
4. For CPE305/CPE310, move the RDSD direction switch to the right (DOWNLOAD), then momentarily
depress the START pushbutton. For CPE330, depress the RDSD DNLD pushbutton.
5. Do not remove the RDSD from the CPU during the transfer.
▪ If the target name in the RDSD is different from the target name in the RX3i, the RDSD LED will
blink red. If this is expected or acceptable, momentarily depress the START pushbutton again.
▪ The RDSD LED blinks green during the transfer. This can take from 10 – 150 sec, depending
upon the size of the project data.
▪ The RDSD LED should turn solid green, indicating that the transfer completed successfully.
Unless the RUN/STOP Switch has been disabled in the hardware configuration just stored, it
can be used to place the RX3i into RUN Mode after the transfer.
▪ If the RDSD LED turns solid red, the transfer has failed.
- The target memory area(s) in the CPU are cleared. For example, if only the Logic is being
download from the RDSD and the store fails (e.g. stick pulled, problem with transfer or
data), Logic memory is cleared following the failed RDSD download. If other memory
areas were also queued up for transfer, those memory areas are also cleared as a result
of the failure.
- 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.
- If the RDSD LED turns solid red, indicating an error, another RDSD operation cannot be
initiated until the device is disconnected then reconnected.
