Setup Procedure
1 Install the Ladder Monitor CD-ROM onto a PC installed with GP-Pro EX. Run Setup.exe on
the CD to launch the installer. Follow the installer instructions to install.
• Your PC must have GP-Pro EX Ver.2.00 or later installed. For the OS, see
the GP-Pro EX Reference Manual.
2 Install the startup file on a CF Card.
Install the CF Card onto your PC. Designate the drive where the CF Card is located to
automatically install the file.
• To use this feature, the CF Card must have 100 MB or more of free space.
3 Create a project file.
There are four ways to start the Ladder Monitor. To start the monitor without using the
system menu, you must configure the settings for starting the Ladder Monitor in GP-Pro EX
in advance.
• System menu
• Switch parts
• LS area
• System variables:
#H_LadderMonitor (no cache)
#H_LadderMonitorCache (with cache)
• To start up using the system menu, see the following pages.

• Ladder Monitor
Reads the ladder programs from the PLC every time you click the switch.
The real-time ladder program is always displayed but it may take time to update the
program status.
• Ladder Monitor (Cache)
Reads the ladder programs saved on the CF Card when you click the switch, reducing the
read time.To update the ladder programs on the CF Card, in [Main Screen] on the GP,
select [Read].

Monitoring the PLC Ladder Programs on a Display
• Read the cache from a CF Card
Normally, every time you start the Ladder Monitor, it communicates with the
PLC to read the ladder programs and it may take time to display the ladder
programs. To improve the display update speed, the Ladder Monitor feature
reads the PLC ladder programs onto the device CF Card (cache) first and
then displays them.
Reading to the CF Card (cache)
If you change the ladder programs on the PLC after reading the PLC ladder
programs to the display CF Card, read the ladder programs to the CF Card
again. In [Main Screen] on the GP, select [Read].
) “3.1 Main Screen” (page 3-2)
• To speed up the comment file display speed, create the following folder on the
CF Card to copy the project comment file (∗.WCD) created with the GXDeveloper programming tool by Mitsubishi Electric. This saves reading on the
PLC and allows for faster reading.

Illuminated in red during capturing
2 The displayed screen is captured and saved on the CF Card. The file name is “CP∗∗∗∗∗.jpg”
and ∗∗∗∗∗ is an automatically assigned number from 0 to 65535.
• The time required for screen capture differs depending on the image quality
and screen size. The file size for an image quality of 80 is approximately
200k bytes, and the capture (snapshot) takes 5 to 6 seconds. To change the
image quality, from the GP-Pro EX [System Settings], point to [Display
Unit] and select [Mode]. In [Screen/Video Capture Settings] change the
[Capture Image Quality] setting.
• If you continuously touch the capture (snapshot) button, the screens may not
be captured properly. Allow some time between captures (snapshots).

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 PLC manual.
• To use this feature, your CF Card must have 100 MB or more of free space.
• To monitor a bit device used in a FUNC instruction, the Word data of the bit address
divided by 16 is displayed in hexadecimal notation.
• When reading the ladder program, you cannot read only the comment file.
• Up to 24 lines are displayed per circuit. The 25th line and after are not displayed. If you
specify a device located in the 25th 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 of
Japan.) If using another company’s CF Card, damage may occur to the CF Card data.
• Devices such as indexing device or indirectly specified device will display the original
monitor data values. (D200Z0 will display the monitor data D200, @D100 will display
the monitor data D100.)
• Monitoring the ladder program from the same PLC with plural display, the
communication error may appear.
