BYTE_TO_BUF example

Data type declaration:

TYPE
   dtStruct: STRUCT
      byteElem : BYTE;
      wordElem : WORD;
   END_STRUCT;
END_TYPE
TYPE
   BYTE_ARRAY : ARRAY[0..200] OF BYTE;
END_TYPE

'Variables' table with declarations:

Code:

A structure element 'data.byteElem' is used in this example. At first the value to be copied has to be assigned from the variable 'byteElem' to the structure element. Of course it is possible to use the variable 'byteElem' as well as the SRC.
After a rising edge has been put to the REQ input, the copy process starts. TRUE is written to the variable 'DoneByte' if the writing process is finished and the value AB is copied from the SRC structure element 'data.byteElem' to the 'byteStream'.
