Precautions for Correct Use
NX102 CPU Unit, NX1P2 CPU Unit, and NJ-series CPU Unit
• To specify an I/O memory address for a tag, create a variable with an AT specification of the
I/O memory address on the Sysmac Studio, and then specify the variable with the AT specifi-
cation for the tag.
For NX102 and NX1P2 CPU Units, you need to set CJ memory to use the I/O memory ad-
dress. For details on CJ memory setting, refer to the
NJ/NX-series CPU Unit Software User's
Manual (Cat. No. W501)
.
• If you enter the following I/O memory addresses for tag names on the Network Configurator,
the tags are directly assigned to the I/O memory addresses in the CPU Unit, and not to the
variables. Always specify variable names for tags.
a) Variable names that contain only single-byte numerals from 0000 to 6143
b) Variable names with the following single-byte letters (uppercase or lowercase) followed
by single-byte numerals
• H (H000 to H511)
• W (W000 to W511)
• D (D00000 to D32767)
• E0_ to E18_ (E0_00000 to E0_32767, to E18_00000 to E18_32767)
You can check the memory address or variable to which a tag is assigned, with icons in the
Edit Tags
Dialog Box.

• If you apply the notation that specifies the above I/O memory address for a tag name, a Tag
Name Resolution Error occurs. A tag data link will not be started.

Input the size of the tag in bytes in the
Size
Field.
Specify the tag size to be the same as the data type size of the variable.
To use a BOOL variable, select the
Use Bit Data
Check Box, and enter
1
in the
Size
Field.
5
Click the
Regist
Button to register the tag.
If an I/O memory address is specified as the tag name, another
Edit Tag
Dialog Box will be
displayed with the next address as the tag name so that you can register the next tag consecu-
tively.
After you register the tags, click the
Close
Button.
6
Click the
Out - Produce
Tab, and then click the
New
Button.
The
Edit Tag
Dialog Box is displayed. Input output tags in the same way.
In case a major fault occurs in the CPU Unit, use the
Fault Action
setting of the output (pro-
duce) tag to select whether to clear output data or continue to send data.
The
Fault Action
setting is not required for input (consume) tag sets.
• Retain output after major fault:
Hold
(default)
Output data maintains its previous status even after a major fault occurs.
• Clear output at major fault:
Clear
