Click the
In - Consume
Tab, and then click the
New
Button. The Edit Tag Dialog Box is dis-
played.

Enter the variable name directly into the Name Box. ( Example: Var_In_a)
Additional Information
•
You can use the following characters in tag names. 0 to 9, A to Z, a to z, single-byte kana, _
(underbar), and multi-byte characters (e.g., Japanese)
•
You cannot use the following characters in tag names. ! “ # $ & ‘ ( ) * + ‚ - . / : ; < = > ? @ [ ] ^ ‘
% spaces or text strings that start with numerals (0 to 9)
•
The maximum length of a tag name is 255 bytes.
•
Specify array and structure variables as shown below.
•
Specifying array elements: array [2][3] (or array [2,3]) and array [2][3][4] (or array [2,3,4])
•
Specifying structure members: Struct.member (Separate the member name with a period.)
Precautions for Correct Use
Precautions for Correct Use
Specify the variable names for tags.
To specify an I/O memory address for a tag, do not specify the I/O memory address for the tag
directly. Instead, create a variable, set an AT specification of the I/O memory address on the Sys-
mac Studio, and then specify the variable with the AT specification for the tag. If you enter I/O
memory addresses for tag names on the Network Configurator, as shown below, 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.
1) Variable names that contain only single-byte numerals from 0000 to 6143
2) 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 the icons in the
Edit Tags Dialog Box.
