(5) Communication with QD75
There are two methods for communication with QD75 using the sequence
program: a method using an "intelligent function device" and a method using a
FROM/TO instruction.
In the sequence program in this chapter and subsequent, the program example
using the "intelligent function device" is shown without using a FROM/TO
instruction for communication with QD75.
When using the FROM/TO instruction for communication with QD75, 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 instruction, change the instruction to a TO instruction.
