(5) Control unit

In the program, the unit of "0 (mm)" is set f or the basic parameter 1.

(6) Communication with QD75

There are two methods for communication with QD 75 using the sequence

program: a method using an "intelligent functi on device" and a method using a

FROM/TO command.

In the sequence program in this chapter and s ubsequent, the program example

using the "intelligent function device" is shown without using an FRO M/TO

command for communication with QD75.

When using the FROM/TO command for communic ation with QD75, change the

circuit incorporating the "intelligent functi on 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 T O command.
