1-1 Overview
The I/O Comment Extracting Tool extracts I/O comment data of the ladder circuit created
on the CX-Programmer, and converts to the data for the NS-series Ladder Monitor.
The source data used for extracting I/O comments is in CXT file format. (CS/CJ-series
PLCs are supported by this program.)
CXT file
(*.cxt)
I/O comments are extracted from the global symbols table and local symbols table in the
specified PLC in a CXT file and converted to an I/O comment file (extension .ioc) for the
NS-series Ladder Monitor.
Save the I/O comment file (extension .ioc) in a Memory Card and place it in the PT.
Specify the I/O comment file (extension .ioc) to be read on the Ladder Monitor screen of
the system menu.
I/O comments created on the CX-Programmer will be shown at the corresponding
address on the Ladder Monitor screen.
Note: The CXT file is a text-based format file that has the same information as the project file
With Ladder Monitor version 3.0 and higher, it is possible to read and display I/O
comments from a symbol table saved in a PLC. Because the I/O comment file is created
automatically, there is no need to use the I/O Comment Extracting Tool. The I/O
Comment Extracting Tool is required, however, in the following situations:
•
When the connected PLC does not support symbol table downloads.
•
When the symbol table has not been downloaded to the connected PLC.
•
When an I/O comment file cannot be created because there is no available space in the
PT.
Do not register more than one symbol for the same address in the symbol table. If two
Note
or more symbols with the same address are registered, an unintended I/O comment
may be displayed for the address displayed by the Ladder Monitor (i.e., a different I/O
comment for the same address).

(extension .cxp) of the CX-Programmer. This file is used for exchanging data between the
CX-Programmer and other applications. A CXT file can be created by specifying the type as a
CX- Programmer text file (*.cxt).
