Array Variables (Tags Only)
One-dimensional array variables can be created with the CX-Programmer. An array specification is
used when multiple variables are used with the same data attribute to manage these variables as a
group.
Array variables can be used with NS-series PTs by copying array variables from the CX-Programmer’s
symbol table to the CX-Designer’s symbol table.

♦
Array variables cannot be created with the CX-Designer. Also, the number of array elements cannot
be changed.
♦
All data types except STRING and NUMBER can be set with the CX-Programmer. (The NUMBER
data type is not supported by NS-series PTs.)
Data Structures (Tags Only)
Data structure can be created with the CX-Programmer. In the CX-Designer, a data structure will be
separated into its members, and each will be treated as one variable. Arrays in data structures will be
separated into individual elements and each will be treated as a separate variable. Members and ele-
ments can be created as individual variables in the CX-Designer.
2-5-3 Directly Specifying Addresses
Address Settings
Addresses are specified using the following formats.
Bit Access
• Internal Addresses: [Memory area name][bit number]
Example: $B1, $SB20
• Specifying Host Addresses:
[Host name]:[area name][5-digit word number].[2-digit bit address]
Example: HOST1:00001.11
Word Access
• Internal Addresses: [Memory area name][word number]
Example: $W00001
• Specifying Host Addresses: [Host name]:[area name][5-digit word number]
Example: HOST1:DM00001
The address settings can be entered directly or from the Address Settings Dialog Box.
Address Setting Dialog Box
The following three methods can be used to input set the address in the Address Setting Dialog Box.
• Directly specifying the address
• Inputting a symbol (For details on symbols, refer to the heading Symbols below.)
• Selecting a registered symbol
Method 1: Directly Inputting an Address
Select the Input Direct Address Tab from the Switch Input Options. Specify the host, area, and
address (“number”).
