This reads the ladder programs onto a CF Card.
• The read button triggers saving of only ladder programs and comments
to the CF Card. It always reads and displays the latest numeric values
from the connected device.
If you change the ladder programs or comments on the PLC after reading
the data of the connected device to the CF card of the display, the Ladder
Monitor for the display will not be updated. Read the data again to update
the saved data.
Cache the ladder programs on the CF Card to increase the display speed
instead of reading data from the connected device every time.
• Create the folder below CF Card to speed up comment display. Copy
comment files (*.WCD) created with the GX-Developer Ver. 8
programming tool by Mitsubishi Electric Corporation to this folder. This
reduces the time taken to display comments because it does not involve
reading from the connected device. When using the Mitsubishi Electric
Corporation A Series Computer Link Driver, create a folder with the
name of the device, and save comment files in it.

Note the following points when displaying comment data read from a
CF Card:
• Do not change the names of comment files created with the GX-
Developer programming tool by Mitsubishi Electric Corporation.
• Comment files are displayed as either program-specific comment files
(MAIN.WCD, SUB1.WCD) or universal comment files
(COMMENT.WCD).
• When both kinds of comment file exist in a folder where comment
files are saved, program-specific comment files are displayed
(MAIN.WCD, SUB1.WCD).
For details on comment and ladder files, see below.
