2.2.2 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.2
Install the startup file on a CF Card.1) Install a CF Card onto the PC.
2) Start the installer by clicking on the Setup.exe file on the ladder monitor CD-ROM.
3) Select the setting language.
4) The OMRON Corporation CS/CJ Series PLC Ladder Monitor Setup Program will launch.
Enter the serial no. and key code. A window appears prompting you to select an install location. Set the CF Card root directory (i.e. the top directory) as the install location.
5) The startup file will be installed.
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)
• Your PC must have GP-Pro EX Ver.2.00 or later installed. For the OS, see the GP-Pro EX Reference Manual.
• To use this feature, the CF Card must have 256 MB or more of free space.
• To start up using the system menu, see the following pages.

2) Double-click the switch you placed and in [Special Action] select [Start monitor switch]. In [Action], select [Ladder Monitor] or [Ladder Monitor (Cache)].
• Ladder Monitor
Reads the ladder programs from the external device every time you click the switch.
The ladder program that is being forwarded is displayed on the external device but it may take time to read.
• 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 display, select [Read].

3) Select [Select Shape], [Color], [Label], and any other features you require and click OK.
• 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 ladder programs of the external device onto the device CF Card (cache) first and then displays them.
If you change the ladder programs on the external device after reading the ladder programs of the external device to the display CF Card, read the ladder programs to the CF Card again. In [Menu Bar] on the display, select [Read].

Start up procedure from the LS area
The Ladder Monitor starts up if you turn ON bits in the LS area. Configure the settings for turning ON the following bits using switch parts and D-scripts.
Bit 1 Turn ON to start up the Ladder Monitor.
Bit 3
Turn ON to start the Ladder Monitor and display the ladder programs cached on the CF Card.
• If the programs are not cached in advance, the bit only triggers the same action as Bit 1 turning ON (starts up the Ladder Monitor). To update the ladder programs on the CF Card, in [Main Screen] on the display, select [Read].

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 external device.
If you change the ladder programs or comments on the PLC after reading the data of the external 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 external device every time.
• To display the comment line, copy the comment file (***.ocm) into the folder below the CF card.
