"Beginner's
Guide to PLC Programming" will
• define the most commonly
used terms, such as rung, bit, input, output, etc.
• explain relay ladder logic
in simple, easy to understand terms
• give you the "13 Marks
of a Well Written Program"
• explain Machine Diagnostics
and how to use them
• save money and save time
The ebook is the result of 16 years of experience in PLC programming, electrical design and engineering. It summarizes dozens of techniques
that are needed to write a solid program.
It has easy to understand text with relay ladder
logic routines that can be used again and again.
You learn how to use coils, contacts, internal
bits, latches, timers, safety rungs, addressing, inputs, outputs .
. . and more.
Sample Ladder
Logic
With drawings and illustrations, you are guided through the steps
of writing programs for PLCs. Here is a small excerpt from the tutorial:
After the part has been moved
into position, the PLC will instruct the machine to clamp
the part in place. This is done by energizing OUTPUT11, which
turns on solenoid SOL11. The solenoid moves the actuator
which holds the part.
You will notice that the branch in the rung contains the logic
to provide a manual method of holding the part for machine
set-up and maintenance.

Here is more of
what you will get:
It's best to start a program
by evaluating any safety switches and setting a master bit.
Then, you can use this bit throughout the program to turn off
outputs immediately when the machine shuts down.
In this case, a latch is used to set an internal "System Running"
bit. If the emergency stop is clear, and the machine guard is
in place, and there is no system fault the operator may press
the start button to set the latch. If the stop button is pushed
or a previous conditions ceases to exist, the "System Running"
latch will drop out.
Most of the time, the order of the bits in a rung doesn't matter
in relay ladder logic. We could have rearranged any of the bits
in this rung, though we would still have to put the latch around
the Start pushbutton. The PLC wouldn't care and the output coil
would still respond the same. However, to make the rung easier
to read, I try to place bits from left to right in order of
importance. If the E-Stop is not cleared, then nothing else
should matter anyway. Having the safety guard in place is more
important than a system fault. Now, if those requirements have
been met, we can press the start button. And we don't care about
the stop button until we have pushed the start button.

Online Tutorial
|  In
addition to the ebook, you also get access to an online course
to let you see ladder logic in action. You learn by watching.
The online tutorial runs for about an hour. You can pause the
course, review the material and put extra time into particular
sections as you wish. It is available 24 hours a day, 7 days
a week.
You may also download the course to your computer so that you
view the course when you are offline.
PLC training has never been more readily accessible. It's like
having your own tutor!
