9-8 OPENNET CONTROLLER USER’S MANUAL
BMOV (Block Move)
Valid Operands
For the valid operand number range, see page 6-2.
▲ Internal relays M0 through M2557 can be designated as D1. Special internal relays cannot be designated as D1.
When T (timer) or C (counter) is used as S1 or N-W, the timer/counter current value is read out. When T (timer) or C
(counter) is used as D1, the data is written in as a preset value which can be 0 through 65535.
Make sure that the last source data determined by S1+N–1 and the last destination data determined by D1+N–1 are within
the valid operand range. If the derived source or destination operand is out of the valid operand range, a user program exe-
cution error will result, turning on special internal relay M8004 and the ERROR LED on the CPU module.
Valid Data Types
When a bit operand such as I (input), Q (output), M (internal relay), or R (shift register) is designated as the source, N-W,
or destination, 16 points (word data type) are used.
When a word operand such as T (timer), C (counter), D (data register), or L (link register) is designated as the source, N-
W, or destination, 1 point (word data type) is used.
Example: BMOV
Operand Function I Q M R T C D L Constant Repeat
S1 (Source 1) First operand number to move XXXXXXXX ——
N-W (N words) Quantity of blocks to move XXXXXXXX X —
D1 (Destination 1) First operand number to move to — X ▲ XXXXX ——
W (word) I (integer) D (double word) L (long)
X ———
S1, S1+1, S1+2, ... , S1+N–1 → D1, D1+1, D1+2, ... , D1+N–1
When input is on, N blocks of 16-bit word data starting with operand
designated by S1 are moved to N blocks of destinations, starting with
operand designated by D1.

When input I0 is turned on, data of 5 data registers starting with D10 desig-
nated by source operand S1 is moved to 5 data registers starting with D20
designated by destination operand D1.
