• Buffer memories are classified into the independent use type (16-bit [S]) and the consecu-
tive use type (32-bit [D]). For 32-bit data such as the current position, add "[D]" to the
FROM/TO instruction.
When you would like to treat a buffer memory of the consecutive use type as the 16-bit type,
turn on the special auxiliary relay M9014 (BFM #20 b14). Then, you can use it as 16 bits in
the FROM/TO instruction (without "[D]") in a program. However, you cannot treat special
data registers (D9000 and later) as the 16-bit type.

Normal operation (M9014 OFF).
Transfer D1, D0(32-bit) to BFM #101, #100(32-bit).
16-bit data sent is automatically converted to 32-bit
data.

When the 16-bit command (BFM #20, b14) is ON,
16-bit data sent is handled as 16-bit data.
