Fixed buffer data area

The manual for the Q corresponding Ethernet interface modules shows the fixed buffer data areas No.1 to No.8 but does not show No.9 to No.16. Are the areas unavailable?
Category : 

Answer

The fixed buffer data areas in the buffer memory are used for communication for FROM/TO instructions. The areas used in communication for FROM/TO instructions are given the range from No.1 to No.8 in consideration of compatibility with existing models.
When in need of the full range of No.1 to No.16, use the instruction "BUFSND/BUFRCV".
