■ Reference Information
AT Settings (Specified Address)
AT settings can be made in the variable properties to specify allocation
addresses for Basic I/O Units, Special I/O Units, or CPU Bus Units, or Auxil-
iary Area addresses not registered using the CX-Programmer. A variable
name is required to achieve this. Use the following procedure to specify an
address.
1. After inputting the variable name in the New Variable Dialog Box, click the
Advanced Button. The Advanced Settings Dialog Box will be displayed.
2. Select AT (Specified Address) under AT Settings and input the desired ad-
dress.
The variable name is used to enter variables into the algorithm in the func-
tion block definition even when they have an address specified for the AT
settings (the same as for variables without a specified address).
For example, if a variable named Restart has an address of A50100 spec-
ified for the AT settings, Restart is specified for the instruction operand.
Array Settings
An array can be specified to use the same data properties for more than one
variable and manage the variables as a group.
Use the following procedure to set an array.
Instruction input. Function block internal variable registered.
Select AT. Input address.
