There are two methods for communication with QD70 using the sequence
program: a method using an "intelligent function device" and a method using a
FROM/TO command.
When using the FROM/TO command for communication with QD70, change the
circuit incorporating the "intelligent function device" as follows.
(a) When the circuit uses the "intelligent function device" on the destination (D)
side of a MOV command, change the command to a TO command.

(b) When the circuit uses the "intelligent function device" on the source(s) side
and the destination (D) side of a MOV command, change the command to a
FROM command and a TO command.
