Operands:
m
1
: Specialty module number
m
2
: CR (Control Register) number of the special module
S
: Data address of the data to write to the specialty module
n
: Number of words to write
Description:
1. Range of
m
1
(16-bit and 32-bit): for ELC-PB/PC/PA/PH, ELCB-PB, ELCM-PH/PA: 0 ~ 7, for
ELC-PV: 0 ~ 7, 100 ~ 107. (0-7 are right-side modules and 100-107 are left-side modules).
2. Range of
m
2
(16-bit and 32-bit): for ELC-PB/PC/PA/PH, ELCB-PB: 0 ~ 48, for ELC-PV: 0 ~
499, for ELCM-PH/PA: 0 ~ 255.
3. Range of n:
a) 16-bit: for ELC-PB/PC/PA/PH, ELCB-PB: 1 ~ (49 –
m
2
), for ELC-PV: 1 ~ (500 –
m
2
) , for
ELCM-PH/PA: 1 ~4
b) 32-bit: for ELC-PB/PC/PA/PH, ELCB-PB : 1 ~ (49 –
m
2
)/2, for ELC-PV: 1 ~ (500 –
m
2
)/2, for
ELCM-PH/PA: 1 ~2.
4. When
S
is a bit operand, K1~K4 can be used for 16-bit instruction and K1~K8 can be used for
32-bit instruction.
5. Flag: M1083 FROM/TO mode exchange.
6. ELC-PB, ELCB-PB series doesn’t support the index registers E, F.
Program Example:
1. Using the 32-bit instruction DTO, the program will write D11 and D10 into CR#13 and CR#12
of the specialty module#0.
2. The instruction will be executed when X0=ON.
X0
DTO K0 K12 D10 K1
The rule of instruction operand:
1.
m
1
: The number of the specialty module. The right specialty module closest to the ELC
controller will be assigned 0, the next closest will be assigned 1, etc. for a maximum of 8
