Using Variables
All operations performed in AutoMax programs use symbolic names (variables) to
represent storage locations for inputs, outputs, and other data. You use these variables
to reference ladder instruction input and output parameters.
With the Editor you name variables just as you do in the Variable Configurator. Variable
names can be a maximum of 16 characters. The valid characters are AćZ, aćz, 0ć9, and
_ (underscore). Names must begin with a letter.
The type of variable you choose depends upon the type of operation to be performed.
Variables are either:
D simple stores a single piece of data
The data can be Boolean, integer, or double
integer.
D array stores a collection of data of the same data type
The data can be Boolean, integer, or double
integer.
D data structure stores both Boolean and double integer data
Data structures are used for Timer and Counter
data types.
You can use preĆdefined keywords to help you
specify the individual timer and counter
elements.
