Attribute
R: This buffer memory can be used only for read. You should not write it.
R/W: This buffer memory can be used both for write and read. When reading or writing data,
use a 16-bit instruction for a buffer memory classified as "S", or a 32-bit instruction for a
buffer memory classified as "D".
• As to word devices, the buffer memory No. is equivalent to the special data register No.
*1: D9300 to D9305 and D9500 to D9505 are assigned as parameters to detect the absolute posi-
tion. Because absolute position detection is executed when the power of the positioning unit
turns on, buffer memories cannot be used to actuate absolute position detection. (However,
such buffer memories can be read.)
To set parameters to detect the absolute position, use a peripheral unit dedicated to positioning.
Have in mind that a peripheral unit dedicated to positioning is also required when the table
method described later is used in the FX
2N
-10GM.
• The execution time of a transfer instruction (FROM/TO) to the buffer memory #32 or later is
approximately twice the regular execution time.
• File registers (#4000 to #6999) are valid only for [D] FROM instructions.
[D] TO instructions are not executed.
