Control

FNC 70 to FNC 79 provide instructions to receive data from and send data to external devices mainly using inputs and
outputs in PLC.
Because these instructions easily achieve complicated controls with a minimum required sequence program and
external wiring, they are similar to handy instructions described in the preceding chapter.
FROM and TO instructions, essential for controlling special units and special blocks, are included in this group. (In
FX

3U

 and FX

3UC

 PLCs, transfer can be also executed using a MOV instruction.)
