The data stored in the source device (S) is copied to
every device within the destination range. The range
is specified by a device head address (D) and a

quantity of consecutive elements (n). If the specified number of destination devices (n)
exceeds the available space at the destination location, then only the available destination
devices will be written to. Please note that double word (32 bit) operation can only be
performed by FX units with ver 3.07 CPU’s or greater and FX

2C 

units.

Operation 1: (Applicable units: FX and FX

2C

).The contents of the two destination devices D

1

and D

2

are swapped, i.e. the complete word devices are exchanged. Ex.

Operation 2: (Applicable units: FX

(2C)

) This function is equivalent to FNC 147 SWAP The bytes within

each word of the designated devices D

1 

are exchanged when ‘byte mode flag’ M8160 is ON. Please note

that the mode will remain active until it is reset, 

i.e. M8160 is forced OFF. Ex.
