(5) Control unit
In the program, the unit of "0 (mm)" is set for the basic parameter 1.
(6) 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 command.
In the sequence program in this chapter and subsequent, the program example
using the "intelligent function device" is shown without using an FROM/TO
command for communication with QD75.
When using the FROM/TO command 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 command, change the command to a TO command.
