Downloading A Project From The Rdsd To The Cpu - Emerson PACSystems RX3i User Manual

PACSystems™ RX3i and RSTi-EP CPU Reference Manual

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.

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 PAC 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 CPE302/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.

CPU Features & Specifications
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
seconds, 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.
