2-1 Starting the Ladder Monitor
Use a Memory Card to start the Ladder Monitor with the following procedure for
pre-version-1 NS-series PTs and version-1 NS-series PTs, or when NS system version
6.5 or lower is used. The Ladder Monitor has been built into the system program for
version-2 NS-series PTs and NSJ Controllers with system version 6.6 or higher (except
for the NS5-V2 and NSJ5), and the setup procedure is thus not required. Proceed to
Starting the Ladder Monitor on page 32.
In addition, the Ladder Monitor cannot read I/O comments from the PLC in the following
cases.
• When the symbol table has not been downloaded to the PLC
• When the CPU Unit does not support symbol table downloads
In these cases, use the I/O Comment Extracting Tool to create an I/O comment file.
Setting Up the Ladder Monitor
1. Prepare a Memory Card (HMC-EF@@@) beforehand. Copy the folders from the
CX-Designer CD-ROM to the Memory Card placed in the PC card slot in the computer
using the following steps 1 and 2.
Copy
[ldrrmt]
[Idrdata]
[procon]

Application
1) Copy the ldrmt, ldrdata, and procon folders from under the ldrsetup folder in the
CD-ROM to the root directory of the Memory Card.
2) To display I/O comments on the screen while monitoring the program, extract the
I/O comments from the CXT file of CX-Programmer using the I/O Comment
Extracting Tool. Then copy the I/O comment file to the ldrdata folder in the
Memory Card. (Refer to the I/O Comment Extracting Tool Operation Manual for
details on operating the I/O Comment Extracting Tool.)
This operation is not required when I/O comments are read from the PLC.
3) After copying the folders, the folders in the Memory Card will be as follows:
(The Memory Card is treated as drive F in the following table.)
