Uploading And Downloading The Ladder Edit File
It is possible to store the ladder edit file (Filename.LL) in RTU memory so that future edits can be made by
uploading the ladder edit file from the RTU, performing the edits and then downloading the compiled ladder
logic and the new ladder edit file. When the ladder edit file is stored in the RTU, the date, time and file name
are also stored. This allows the file version to be checked using Logic, Advanced, Upload .LL File Details
From RTU (note: the Logic menu is available when the SDB site configuration window is in selected).
The Ladder Edit File is automatically stored in the RTU whenever ladder logic is downloaded if the Store
ladder logic files in RTU check box is ticked in the memory configuration or it can be manually downloaded
using Logic, Advanced, Download .LL File To RTU.
Before a ladder edit file can be uploaded, an RTU configuration (filename.SDB) must be open in Toolbox.
Toolbox then uses the name of this configuration file for the uploaded ladder logic. The RTU configuration
file can be uploaded from the RTU (using Utilities, Advanced, Upload Configuration) or alternatively an
RTU configuration can be opened or created that does not have any ladder logic.
Once an RTU configuration file is open (if the configuration is uploaded from the RTU it must first be saved
using the File, Save As command), the ladder logic can then be uploaded using Logic, Advanced, Upload
.LL File From RTU.
Compare Ladder Version In RTU
When the SDB file is the active window (in front), the Logic menu option will appear. By selecting Logic,
Advanced, Compare ladder version in RTU, the compiled ladder version in the RTU can be compared with
the compiled ladder version in the PC.
To check if the ladder edit file (Filename.LL) in the PC corresponds to the compiled ladder logic in the RTU,
compile the ladder logic on the PC (Logic, Compile) and then select Compare ladder version in RTU. This
will compare the compiled ladder logic file (Filename.LL0) file in the PC with the compiled ladder logic file in
the RTU. If the Size and CRC of the two files match, then all is OK as illustrated below. Different file dates
are unimportant.
Date: Date and time when the ladder logic was compiled.
Size: Number of bytes in the compiled ladder file. Since comments are not included in the compiled file,
changing comments and re-compiling will not affect the LLO file size.
Crc: Returns the hexadecimal value of the CRC (0x denotes hexadecimal). Since comments are not
included in the compiled file, changing comments and re-compiling will not affect the CRC. Note: Always
returns 0 when compiled and downloaded using Toolbox 1.41n and older.
Toolbox Version: Toolbox version used to generate the compiled ladder logic file.
