Siemens S7 200
Lessons
This
is a series of lessons that is for the
beginner programmer just learning how to
program and the seasoned
engineer that is looking to improve their
skills, we are covering everything from
simple pointers to advanced moves and data
manipulation.
We are trying to
teach you something you can not get in a
manuals, the manuals are great and you
should read them, but what we are teaching
you will not get out of a manual, we are
trying to mimic the machines that you will
be working on or building, this is where the
real value of the lessons are... you will
have a understanding on why and how the
logic is working and you will be able to
come up with your own logic in no time at
all.
With over a total
of 50pages (pdf) on just the lessons and 4
.mwp programs this will give you the
knowledge that you need to get started and
continue in the future.
The lessons
1) Basic intro: Download, go online,
viewing program, making a simple program
2) Basic intro: Instructions, Split
Screen, Program Tree, Key features,
Processor Status
3) PLC Cycle Scan's: How the PLC's
looks at the logic and decides what needs to
happen next, this is important if you plan
on any 'automation', this is over looked by
many and they have a hard time understanding
the full concept of programming, the PLC’s
don’t change their mind… its always the same
so once you learn how to read their mind you
can tell what its going to do next.
4) Recording actions with a PLC: In
this lesson we will cover on how to record
and play back (in sequence) an event or
series of actions (inputs) then play them
back as outputs, we will be recording up to
20 inputs… if you are old enough you can
remember the old game Simon Says, this is
similar to that by randomly pushing the
buttons/inputs then switching to the play
back mode the PLC plays back the buttons you
just pushed then the same sequence you
pushed them.
5) Grinder: This lesson
simulates a grinding machine by running a
table up and down and into the grinder
(resurfacing grinder) it will run in
automatic if the correct conditions are
made.
(6) Parts conveyer: (Timers,
Counters, Moves, Sequence Loads, Data
Viewing), Learn how to track a part that is
moving down a production line or conveyor,
by tracking parts you can determine when to
remove a rejected part, speed up or slow
down line speed, run the program/machine in
manual or automatic.
7) Peak HMI: Human Machine
Interface), Using a demo version of Peak HMI
you will learn how an HMI interfaces with
the PLC and is controlled by your PC, HMI’s
are becoming a large part of any
manufacturing/production plants, learning
this is a bit more advanced but this is a
MUST for any system integrator or plant
maintenance personal, this is
the next level… we are working on this one,
when it is finished you will receive it
along with instructions on how to download
and setup the HMI
The lessons include 48 sample programs (very
well documented)
