• Depending on the version, your programming tool may not be able to display ladder
programs. For the versions supporting programming tools, see the Pro-face support site
“Otasuke Pro!”. For the instructions that you can monitor, see the manual of the external
device.
• To use this feature, your CF Card must have 256 MB or more of free space.
• When reading the ladder program, you cannot read only the comment file.
• The maximum amount of lines displayed for one ladder program is 25. The 26th line and
after are not displayed. If you specify a device located in the 26th line or after when
searching for a device, the start of the circuit where the device is located will be displayed
but the specified device itself will not be displayed.
• The power flow is shown by the contact/coil in bold, but the lines connecting contacts to
contacts do not change.
• The time taken for a screen capture depends on the image quality and screen size. The file
size for a screen quality of 80 will be approximately 200 KB and the capture will take
about 5 to 6 seconds.
• If you continuously touch the capture (snapshot) button, the screens may not be captured
properly. Allow some time between captures (snapshots).
• Ladder program and comment password settings are not supported. When a [Stop Read/
Write] password is used, reads will cause a communication error.
• Please use CF Cards manufactured by Pro-face (Digital Electronics Corporation). If using
another company’s CF Card, damage may occur to the CF Card data.
• Only English and Japanese can be used for the font.
• Even when the ladder program has been task reading protected, if the task reading
protection password in PLC has not been set, reading is possible.
• I/O comments cannot be read from the PLC.
• Instance names of function blocks, function block names that are called, and parameter
names will not be displayed.
