Function Block Types

There are three basic types of function blocks:

  • System Avatar function blocks

  • Avatar function blocks

  • Device Asset Management function blocks

The following sections give an overview of the functionalities that each of these function block types provides.

The function blocks in the TeSys™ island function block library for the TIA Portal potentially use both cyclic and acyclic communication with the island. Details on the control mechanisms and parameters involved with the two communication types are given in Data Access.
