Additional Information
Exclusive Control between Tasks
You can restrict writing to global variables to a single task to prevent changes to the values of
global variables during processing. Specify this as a task setting, not as a variable attribute.

Data Types

The Data Type attribute defines the type of data and range of data that is expressed by a variable.
The amount of memory that is allocated when you declare a variable depends on the data type of that
variable. The more memory allocated, the larger the range of values that the variable can express.
The data types for the input, output, and in-out variables of instructions depend on the instruction. Set
the data types of input, output, and in-out parameters for the instruction arguments according to the
data types of the input, output, and in-out variables for that instruction.

Description
An Edge attribute allows you to detect
when the input parameter of a function
block changes to TRUE or changes to
FALSE. This can be used only on BOOL
input variables.
