(5) Control unit
In the program, the unit of "0: mm, 2: degree" is set for the basic parameter 1.
(6) Communication with the Simple Motion module
There are two methods for communication with the Simple Motion module 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 a FROM/TO
command for communication with the Simple Motion module.
When using the FROM/TO command for communication with the Simple Motion
module, 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.
