The instruction supports V devices and Z devices. (If the 16-bit
instruction is used, Z devices can not be used. If the 32-bit
instruction is used, V devices can not be used.)

Explanation
 m
1
: Special module number (m
1
is in the range of 0 to 255.); m
2
: Control
register number (m
2
is in the range of 0 to 499.); D: Data which will be written
into a control register; n: Quantity of data which will be written (16-bit instruction:
1~(500-m
2
); 32-bit instruction: 1~(500-m
2
)/2
 A DVP-20PM series motion controller can write data into a control register in a
special module by means of the instruction.
Example
 The 32-bit instruction DTO is used. The value in (D11, D10) is written into
(CR#13, CR#12) in special module 0. One value is written at a time.
 When X0 is ON, the instruction is executed. When X0 is turned OFF, the
instruction is not executed, and the value which is written remains unchanged.

1. m

is a special module number. It is the number of a special module
connected to the DVP-10PM series motion controller used.
The number of the first special module which is connected to the DVP-10PM
series motion cotroller used is 0. Eight special modules at most can be
connected to the DVP-10PM series motion controller used, and they do not
occupy I/O devices.
2. m

: m
2
is a control register number. the 16-bit memories in a special
modules are called control registers. Control register numbers are decimal
numbers. The operation of a special module and setting values are stored in
the control registers in the special module.
3. If the instruction FROM/TO is used, one control register is taken as a unit for
the reading/writing of data. If the instruction DFROM/DTO is used, two
control registers are taken as a unit for the reading/writing of data.
High 16 bits
Low 16 bits

4. n which is 2 in a 16-bit instruction has the same meaning as n which is 1 in
a 32-bit instruction.
