Ladder Monitor Restrictions

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.

The content of function blocks will not be displayed.

Floating decimal points of monitor values cannot be displayed.

Other program files besides ladder cannot be read or displayed.
