Final Project
PLC (Telemechanique) and Ladder
Logic
Programmable
Logic Controler (PLC):
In
an Industrial Technology class, Robotics 424, under the mentoring
of Dr. G.H. Massiha I was also exposed to programming through
a Programmable Logic Controler (PLC). A PLC is a simple control
device designed specifically for industrial machines that
performs logical operations compatible with traditional relay
logic. In our experiments we used the Telemechanique to perform
desired results. We used LED's to simulate input and output
as well as our results.
In
light of our recent endeavors with the Telemecanique MPC-007
we have demonstrated the capability to control a vast number
of electrical devices. In our theoretical demonstration we
have proven the capability to program switching logic. With
the help of the MPC-0007 input device we essentially programmed
AND OR NOT logic to the device in effort to product desirable
output.
The
most interesting feature of the MPC-007 was its capability
to time specific activities. Internally it holds 80 timers
and 45 counters. It also can do mathematical manipulations,
conversions, and comparisons. It packs 128 shift registers
and 100 data registers. These with the help of some ladder
logic this MPC-007 can perform complex operations.
These
operations could be put into place within any company to automate
their production capabilities. Adding these types of capabilities
to our production would be initially requiring an investment.
But over time if the equipment was maintained properly, this
investment could be better in the long run.
Ladder
Logic:
To
perform these types of experiments we were required to learn
ladder logic. Ladder logic is another way of performing complex
operations. In many ways it is similar to electronic logic
gates. With ladder logic you can perform AND, OR, NOT, etc.
logical operations. Ladder logic is choice for programming
robots because when combined with a PLC allows complex operation
without having to hard wire each electronic gate.
