unexpected operation may result. Always confirm system safety before clicking the
Reset Button.
Note 2:
When the CX-Programmer creates the Special I/O Unit or CPU Bus Unit settings in the
I/O Table Window, it automatically uses the latest version of the CPS file that is
available in the computer.
•
If the actual Unit’s version number is older than the latest CPS file in the computer,
a warning will be displayed when the settings are downloaded to the Unit. A Dialog
Box will ask whether to change the computer’s settings.
In general, click the Yes Button to change the computer’s settings. When the Yes
Button is clicked, the Unit version in the computer’s Unit settings will be changed
to the actual Unit’s version number. (If the No Button is clicked, the version
number in the computer will be newer than the actual Unit’s version number, and
the newer version number will be displayed.)
•
Similarly, if the actual Unit’s version number is newer than the latest CPS file in
the computer when the Unit’s settings are transferred from the PLC to the computer,
the computer’s earlier Unit version number will be displayed. In this case, install
the Unit’s correct (newer) CPS file in the computer. For details, refer to
Installing a
CPS File
below.
If the newer CPS File is not installed, the newer version’s Unit settings cannot be
set and only the older Unit settings (in the older CPS file) can be set.
Note 3:
Storing the Parameter Settings Data File
•
The data set in the Edit Parameters Dialog Box can be saved in a parameter settings
file with a .xml filename extension. To save the parameter settings, right-click the
desired Special I/O Unit or CPU Bus Unit in the I/O table and select
Save
Parameters
from the pop-up menu.
•
The saved parameter settings can also be read from a parameter settings file (.xml
filename extension), but the settings must be for the same model Special I/O Unit or
CPU Bus Unit.
Note 4:
Contents of Parameter Settings Data Files
The structure of a parameter settings data file is based on the parameter settings in the
CPS file. Parameter settings data files contain the following data:
•
Model number, Unit version number, unit number, rack number, and slot number
•
Name of the original CPS file used to create the parameter settings data
•
Parameter names and data
Note 5:
When Special I/O Unit or CPU Unit settings are performed in the I/O Table Window
and then transferred from the PLC Memory Window, the following warning will be
displayed if the allocated DM Area/CIO Area addresses set for Special I/O Units or
CPU Bus Units in the I/O Table Window on the computer overlap with the PLC data
table addresses.
Unless the CPU Bus Unit or Special I/O Unit settings have been previously transferred
to the CPU Unit and the allocated DM Area/CIO Area data in the PLC data table for
Special I/O Units or CPU Bus Units is to be overwritten, always click the No Button,
shift the address, and repeat the transfer procedure.
Note 6:
CPU Bus Unit and Special I/O Unit settings are not checked for logical consistency. Be
very careful of the logical consisting of the overall settings when making any setting
that affects other settings, e.g., settings that enable or disable other settings. Transfer
the Special I/O Unit or CPU Bus Unit settings to the PLC and then start operation,
being aware that any logical inconsistencies may produce unexpected operation. For
example, if one setting selects either user settings or default settings and is set to use the
default settings, it will not automatically change to enable user settings even if the
