Access to Variables in Arrays, Structures, and Blocks Access to array elements Syntax: <name of array variable> [  <comma-separated list of dimension indexes>  ] <name of array variable> Name of the a

Bit Access in Variables Important Implement concurrent bit access by two tasks only if the processor can execute bit access directly on the memory. All x86 and x64 systems have commands for bit access

Data Type: Implicit Enumeration The implicit enumeration allows for an easy way to declare a new enumeration variable which is valid only within the local POU. A variable of this type can take a limit
