About the Dictionary
The Dictionary is a database which holds all your application variables. You should
define all your variables at the start of a new project. Include processor and I/O
module variables and the I/O channel variables.
Note: You can define new variables while creating a program; however, you will be
prompted to add the new variable to the Dictionary.
The AADvance Workbench automatically assigns a set of variable elements when you
select the variable type. The Variables Grid dialog box provides fields for you to
enter or change the properties of your variables. Double clicking on a each variable
field will open a dialog box that allows you to enter the relevant attributes for the
variable.
Properties for AADvance Variables
Name: Limited to 128 characters. Must begin with a letter or underscore character
followed by letters, digits and single underscore characters.
 Example: di_full.
Note: A name cannot have two consecutive underscore characters.
Alias: A name, used in LD Editor. The variable comment text truncated before the ':'
character, and limited to 16 characters including spaces.
Wiring: Read only cell, generated by the Workbench, gives the I/O point that the
variable is wired to. Uses the syntax of a directly represented variable to represent a
free channel, that is a channel that is not linked to a declared variable. The identifier of
a directly represented variable is always %.
 Example: %IXs.c; where 'I' is an input, 'X' is a boolean, 's' is the slot number of the
I/O module and 'c' is the channel number.
