POU, Data Type & Function utilization in EAE application

[anandbpillai]

There is POU, Data Type & Function available in the EAE application but not sure what is the exact purpose and how it is to be mapped in any application.

The help also is not that useful for this topics.

Pls provide any support or document reference for this.

The purpose of POU is to make use of IEC 61131 code.  In order to embed this code inside an IEC 61499 program you should add a PGM block inside the 1499 function block network and trigger the input event from any 1499 function block.  This input will activate the 1131 code.

If you have further questions on this topic please let us know.

Additionally, we are in the process of reviewing and improving the Help content, so I will bring this feedback into our review.

thank you for the reply. @TomRos 

For POU it is ok.

what about Data Type & Function. 

Also as you rightly said the help files needs more update for all of these.

for Datatype is quite straightforward:

- enumeration 

TYPE DataType3 : (item1,item2,item3);END_TYPE

- alias

TYPE DataType2 : BOOL; END_TYPE

-struct

TYPE DataType1 : STRUCT 
item1  : BOOL;
item2  : REAL;
item3  : STRING;
 END_STRUCT;
END_TYPE

-array

TYPE DataType5 : ARRAY[0..4] OF BOOL;END_TYPE

-subranges

TYPE DataType4 : SINT(0..10);END_TYPE

All can be defined as types and then used in variable declarations (interfaces of cats, composites, basics...) or in your symlinks definition

Do you have an example using the PGM Bloc - Cant find it in any existing libraries
