Introduction
Data can be moved using the MOV (move), MOVN (move not), IMOV (indirect move), or IMOVN (indirect move not)
instruction. The moved data is 16 ‐ or 32 ‐ bit data, and the repeat operation can also be used to increase the quantity of
data moved. In the MOV or MOVN instruction, the source and destination device are designated by S1 and D1 directly. In
the IMOV or IMOVN instruction, the source and destination device are determined by the offset values designated by S2
and D2 added to source device S1 and destination device D1.
The BMOV (block move) instruction is useful to move consecutive blocks of timer, counter, and data register values.
The IBMV (indirect bit move) and IBMVN (indirect bit move not) instructions move one bit of data from a source device
to a destination device. Both devices are determined by adding an offset to the device.
NSET (N data set) and NRS (N data repeat set) instructions can be used to set values to a group of devices. The XCHG
(exchange) instruction is used to swap word or double ‐ word data between two devices. The current values of timer or
counter can be changed using the TCCST (timer/counter current value store) instruction.
Since the move instructions are executed in each scan while input is on, a pulse input from a SOTU or SOTD instruction
should be used as required.

Valid Devices
For the valid device address range, see pages 6 ‐ 1 and 6 ‐ 2
(
Basic Vol.).
Internal relays M0 through M2557 can be designated as D1. Special internal relays cannot be designated as D1.
Source device can be both internal relays M0 through M2557 and special internal relays M8000 through M8157 (all ‐ in ‐ one type CPU)
or M8317 (slim type CPU).
When T (timer) or C (counter) is used as S1, the timer/counter current value (TC or CC) is read out. When T (timer) or C (counter) is
used as D1, the data is written in as a preset value (TP or CP) which can be 0 through 65535.
When F (float) data type is selected, only data register and constant can be designated as S1, and only data register can be designated
as D1.
When F (float) data type is selected and S1 does not comply with the normal floating ‐ point format, a user program execution error will
result, turning on special internal relay M8004 and ERR LED on the CPU module.

When input is on, 16 ‐ or 32 ‐ bit data from device designated by S1 is moved to
device designated by D1.
The float data type is available on upgraded CPU modules with system program
version 200 or higher.

When a bit device such as I (input), Q (output), M (internal relay), or R (shift register) is designated as
the source or destination, 16 points (word or integer data type) or 32 points (double ‐ word or long data
type) are used. When repeat is designated for a bit device, the quantity of device bits increases in 16 ‐ or
32 ‐ point increments.
When a word device such as T (timer), C (counter), or D (data register) is designated as the source or
destination, 1 point (word or integer data type) or 2 points (double ‐ word, long, or float data type) are
used. When repeat is designated for a word device, the quantity of device words increases in 1 ‐ or 2 ‐
point increments.
