Like all things that need programming, the
AIS
PLC may seem for the first time
user to be a little difficult to program. However, the sequence programming
language utilized, is designed to make it as easy as possible for you the user
to
create your own sequence programs without the need of specialized help. In fact,
after a very short time you can become very proficient at writing programs which
can perform the simple or complicated operations required
to
meet your application
needs.
Two main types of program construction method are used, both
of them using the
MELSEC
A
dedicated sequence programming language, these are; instruction list
(List mode) and relay ladder logic (Ladder mode). Each of them can perform the
same tasks, the choice of which one to use is purely dependent on the user's
preference. However the most commonly used method is relay ladder logic (Ladder
mode) because of its graphical representation and simplicity.

The
A1S
is a true general purpose PLC which can be used for almost any type of
control application. Example applications of where the
A1S
has been used are; data
link control, positioning control, robot control, analog control, sequence control, data
acquisition, and system monitoring. There are many other types
of
application in
which the
A1S
has been used,
so
whatever your control application, the
AIS
can
probably solve it in an easy
to
implement,
cost
effective way.
