( 10 ) Offset (PARAM08, PARAM09, PARAM10, PARAM11)
Specify an offset address for the reception side data address.
The address for the reception side will be displaced by the number of words designated by the offset.
Note: 1. For more information, refer to G.2.8 Relationship between Data Address, Data Size, and Offset for
MSG-RCV Function on page A-98.
2. The offset cannot be a negative value.
The offset parameter is prepared for each target data type.
The following table lists the offset parameters.
The valid offset parameter may differ according to the function code.
The following table lists the valid parameters for each function code.
