■Applicable devices

SM, F, B, SB,

• In safety programs executed by the Safety CPU, only the following safety devices and constants can be used.

SA\X, SA\Y, SA\M, SA\SM, SA\B

Processing details

• These instructions batch-transfer the (n) points of 16-bit binary data starting from the device specified by (s) to the device

specified by (d).

• Data can be transferred even when the transfer source device and destination device overlap. A transfer to smaller device

numbers begins from the device specified by (s), and a transfer to larger device numbers begins from the device specified

by (s)+(n)-1.

• When (s) is a word device and (d) is a bit device, the number of digit-specified bits in the word device is transferred.

When K1Y30 is specified in (d), the lower 4 bits of the word device specified by (s) are transferred.

• When both (s) and (d) are bit devices, set the same number of digits for both devices.

• To use the link direct device, module access device, or CPU buffer memory access device for (s) or (d), specify it only for

one of the devices. Note that the CPU buffer memory access device (U3E0\G) of the host CPU module in which index

modification is not specified in the I/O No. specification can be specified by both (s) and (d).

Operation error

The link direct device, module access device, or CPU buffer memory access device is specified by both (s) and (d).

However, this is not true when the CPU buffer memory access device (U3E0\G) of the host CPU module in which index modification is

not specified is specified.
