Downloading Procedure
1, 2, 3...
Note 1. The default values for each function block are transferred as operation data
when downloading function blocks. Default values are also transferred to
output ITEMs (e.g., MV) if function groups are downloaded while the Loop
Controller is in operation. Confirm the status of connected devices before
downloading.
2. To check the compatibility of the Loop Controller version for the online con-
nection and the CX-Process version before downloading, select Check
Version from the Run Menu.
(1) Loop Controller Boards (LCBjj)
• Ver. 2.0 or Lower
If LCBjj Ver. 2.0 or lower is used and a Memory Card is not installed in the
CPU Unit, tag, comment, annotation, and block diagram line data will not be
transferred. To transfer this data to a Memory Card, refer to 4-9 Transferring
Tag and Comment Data.
When LCBjj Ver. 3.0 or higher is used, tag, comment, and annotation data
can be stored in the Loop Controller without a Memory Card.
(2) Loop Control Units (LC001)
• Ver. 2.0 or Later
Block diagram information can be transferred partially (only the layout data for
the function blocks). Data on lines between function blocks created in block
diagrams cannot be transferred.
• Ver. 1.5 or Earlier
Block connection line data is not transferred. Consequently, the block diagram
will not be displayed when an upload is performed.
• Step ladder programs created as ladder diagrams will not be transferred when
ITEM 200 (mnemonic flag) for the step ladder block is 1. Always change ITEM
200 (mnemonic flag) to 0, convert into mnemonic code (assemble), and then
perform the transfer.
• To perform an assembly operation for LCU/LCB elements, select Execute –
Assemble All. For step ladder programs, select Operation – Assembly.
Mnemonic code can be transferred when ITEM 200 (mnemonic flag) is 1.
• If a download is executed when ITEM 200 (mnemonic flag) is 0, assembly (i.e.,
conversion from ladder diagram to mnemonic code) will be automatically per-
formed and mnemonic code will be downloaded (automatic assembly).
1. Select the LCU/LCB element (LCB01, LCB03, LCB05, LCB05D, LC001-1 to
LC001-3) or function block and select Transfer to LC – Selected from the
Execute Menu.
The following dialog box will appear unless the data in function blocks are to
be downloaded.
