Function Blocks
The following sections define the interfaces of each of the function blocks of the library, their functionality, and their intended use. Besides names, data types, and a description, for each interface variable of the function blocks, one of the following categories is specified:

Meaning |
|---|---|
|
Function block control |
Input variable to control the execution of the function block (for example, trigger acyclic communication). |
|
Function block status |
Output variable that gives information on the status of the function block execution. |
|
Communication parameter |
Input or in/out variable used to parametrize either cyclic or acyclic data access. |
|
Cyclic data |
Input or output variable that is part of the data transferred through cyclic communication to or from TeSys™ island. |
|
Acyclic data |
Input or output variable that is part of the data transferred through acyclic communication to or from TeSys™ island. |
Additionally, the sections document which values (e.g. which common error and status codes) from ConsTeSysisland (see Data Block ConstTeSysIsland) are used by each of the function blocks.
