*1 Use this variable name for an NJ-series CPU Unit.
*2 Use this variable name for port 1 on an NX-series CPU Unit, or for an NY-series Controller.
*3 Use this variable name for port 2 on an NX-series CPU Unit.
*4 Use this variable name for the internal communication port on an NY-series Controller.

• The size of the variable name is calculated as the total bytes for the ASCII charac-
ters in all structure levels plus two times the number of levels.
• If the number of bytes of ASCII characters in a level is an odd number, add 1.
• If a level in the structure is an array, add four times the number of dimensions in the
array.
• Periods and commas in the structure and arrays are not included in the variable
name size.
Example 1: When the Variable Name of DstDat Is aaa.bbbbb[1,2,3].cc
• The text string "aaa" in the first level is 3 bytes. It is an odd number, so 1 is added
to make 4 bytes.
• The text string "bbbbb[1,2,3]" in the second level is 5 bytes. It is an odd number,
so 1 is added to make 6 bytes.
• Also bbbbb[1,2,3] is a three-dimensional array, so 3 times 4, or 12, is added to
make 18 bytes.
• The text string "cc" in the third level is 2 bytes. It is an even number, so 2 bytes is
used in the calculation.
• If we add the number of levels 3 times 2, or 6, to 4 bytes for the first level, 18
bytes for the second level, and 2 bytes for the third level, the size of the variable
name come to 30 bytes.
Example 2: When the Variable Name of DstDat Is val
• The text string "val" in the first level is 3 bytes. It is an odd number, so 1 is added
to make 4 bytes.
• If we then add the number of levels 1 times 2, or 2, the size of the variable name
is 6 bytes.
Example 3: When the Variable Name of DstDat Is array[8].
• The text string "array" in the first level is 5 bytes. It is an odd number, so 1 is
added to make 6 bytes.
• It is a one-dimensional array. Therefore, 1 times 4, or 4, is added.
• If we then add the number of levels 1 times 2, or 2, the size of the variable name
is 12 bytes.
