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.
MOV (Move)
Applicable CPU Modules
Valid Devices
For the valid device address range, see pages 6-1 and 6-2 (Basic Vol.).
Internal relays M0 through M1277 can be designated as D1. Special internal relays cannot be designated as D1. 
Both internal relays M0 through M1277 and special internal relays M8000 through M8177 can be designated as source devices.
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. For user program execution errors, see Chapter 4 “User Program
Execution Errors” on page 4-21.
Valid Data Types

W (word) X 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.
