*1<TAGNAME>: The Tag Name includes the structure name if structure is required. The maximum number of characters for a Tag Name is 255 including delimiters and element number.

Ex.) BOOL type single tag: "BOOLTAG"
BOOL array element: "BOOLARRAY[5]"
INT type single tag: "INTTAG"
WORD type bit address: "WORDTAG.15"
DINT type bit address: "DINTTAG.31"
STRING type word address "STRINGTAG"

It is possible to use alphanumeric characters (upper and lower case) as well as underscore for both Tag Names and Element Names.

- The maximum number of characters is 127.

- Numbers and underscore cannot be used for the first character.

- The use of two underscore in succession is not possible.

- The use of [! " # $ % & ' ( ) = - ~ ^ | ` @ { [ + ; * : } ] < > , . ? /] and spaces are not possible.

*2Array: Number of array element is included in the controller tag information. When the element number starts from 0, maximum element number is [Element Number-1].

INTARRAY INT[256,256] can be used in the range of INTARRAY[0-255,0-255].

Array's maximum element number is 65535 including 2D or 3D.

1D Array EX: ARRAY[65535](INT) Element number: 65535

2D Array EX: ARRAY[2,32767](BOOL) Element number: 65534

3D Array EX: ARRAY[1,1,16383](DINT) Element number: 65532

*4STRING: Available to define only 1 dimension. Maximum number of characters is 1986 half size characters.

*5The number of elements for each dimension is shown from "l" (the first number of the elements) to "h" (the last number of elements).

NOTE

- Only 1-dimensional array tags that use 0 as the first number of the elements can be applied to variables created by the user. However, tags acquired through a Symbol Link can use up to 3 dimensions and there is no limit to the first number of the elements.
- When using the NJ series, set the [String Encode] to UTF8 under the BLUE System Configuration.
- Set the character encoding of the Symbol file (txt file) used for the Symbol Link to UTF-8. The Symbol file is created by pasting the tag list that was output to the clipboard from the OMRON ladder logic software.
- Please refer to the precautions on manual notation for icons in the table.
