Logix 5000 Function Blocks

[Sergei Troizky 26]

I am using CompactLogix 5370 PLC (1769-L36ERM) and Studio5000 v30.

The help file mentions function blocks, but there is nothing related in the software, only Add-On Instructions.

AM I missing something?

Rockwell's Add-On Instruction is equivalent to Omron's Function Block.

The Function Block you see in the help files is Function Block Diagram. When you create a new Routine, you can choose Ladder, Sequential Function Chart, Function Block Diagram, or Structured Text. So it's just a different method of programming.
