CX-Process Tool
CSV Tag Files for SCADA
Software (.csv, Default
File Name: TagList.csv)
Tag Files for RS View
(.csv, User-set File Name)
Comment Files (.cmt)
CX-Server Settings File
(.cdm)

The file contains the tag names, tag comments, scaling upper limits, scaling low-
er limits, scaling decimal point, units, and other settings for each function block.
The data is comma delimited.
Note This file does not contain the tags for individual ITEMs in function block or ad-
dress allocations for CPU Unit I/O memory. (These are stored in the CSV tag
files for SCADA software after the CSV tags have been compiled.)
This file is automatically generated after CSV tag settings have been made after
selecting Settings – Tag Setting – CSV Tag or (for CX-Process Tool software
version 3.1 or higher) when function blocks are saved in function block files after
selecting the automatic CSV tag registration option when registering function
blocks.
This file is saved in the data project folder under the CS-Process installation
folder as project_name.csv.
The CSV automatic tag registration function can be used with version 3.1 or
higher to automatically save CSV tag settings in this file when function blocks
are registered. The tag name will be Tag + block address, the scaling upper limit
will be 1,000, and the scaling lower limit will be 0.
If this file is edited with Excel or another editor and overwritten, the new settings
will be read when the project is opened.
A CSV tag file can contain CSV tag data for up to 32 CPU Units (i.e., up to 96
Loop Control Units and 32 LCBjjs).
CSV tag data consists of comma-delimited test data containing tag names, num-
bers, tag comments, block addresses, tag ITEMs, and allocated I/O memory ad-
dresses (in CPU Unit).
The CSV tag file can be read from SCADA software via an OMRON OPC Server
to specify block addresses and ITEM numbers in the function block data of the
Loop Controller.
Settings – Tag Setting – CSV Tag is used to set CSV tags for each function
block, and Execute/Create Tag File/CSV Tag is used to allocate I/O memory ad-
dresses in the CPU Unit and compile a CSV tag file.
Note 1. CSV tag files are not downloaded, uploaded, or compared.
2. Basically speaking, CSV tag files are imported to SCADA software through
an OMRON OPC server.
An RS View tag file can contain CSV tag data for up to 32 CPU Units (i.e., up to 96
Loop Control Units and 32 LCBjjs) for direct importing into RS View 32. Any
file name can be specified.
The RS View tag file can be directly imported using the RS View import utility.
This file is created together with the SCADA CSV tag file when the RS View CSV
tags are compiled using Execute/Create Tag File/RS View Tag. When this file is
imported into the RS View 32 using the import utility, the ITEMs and tags speci-
fied with CSV tag settings are registered in the tag database in the RS View 32
project.
Note 1. RS View tag files are not downloaded, uploaded, or compared.
2. The SYSMAC OPC Server Version 2.40 or higher is required to generate an
RS View tag file from the CX-Process Tool.
A comment file contains of the tag data attached to a function block connection
diagram or step ladder diagram.
The file name is automatically set to the same name as the project.
This file contains the communications settings for communications with the PLC
when CX-Server is being used as the communications driver.
The file name is automatically set to the same name as the project.
