I/O refreshing and the user program are executed in units that are called tasks.
Tasks are used to specify execution conditions and execution priority.

POUs that are assigned to tasks
POUs that are used to create objects with specific conditions
POUs that are used to create objects that determine unique outputs for the inputs,
such as for data processing

Basic data types, structures, unions, enumerations, array variables
You can use member offsets to place structure members at any memory locations
A derivative data type that enables access to the same data with different data types
4
BOOL, BYTE, WORD, DWORD, LWORD
A derivative data type that uses text strings called enumerators to express variable
values
An array is a group of elements with the same data type. You specify the number
(subscript) of the element from the first element to specify the element

Supported
You can specify a range for a data type in advance. The data type can take only
values that are in the specified range
