ABSTRACT
The purpose of this Programmable Logic Controller (PLC) is to command 16
relays in different sequences programmed by user. This device is applicable for
controlling and monitoring industrial processes and may be implemented in multiple
domains, from auto industry and home control applications to industrial instruments,
remote sensors and security devices. It’s also ideal for battery powered devices
because it’s low power consumption. EEPROM memory make easier the
implementation of the microcontroller on devices where permanent memory is
needed to store different parameters (codes for transmitters, motor speed, receiver
frequencies). The controller can be used in small industry in controlling and
monitoring industrial processes. Depending of the programmed software, the device
can
i) command a packing line
ii) count the products from an industrial process line and display the result on
any kind of display, and
iii) communicate with dedicated PLC’s using digital level shifters.
Key words: Programmable Logic Controller, EEPROM.
INTRODUCTION
An industrial PLCs system is used for the development of the controls of machinery. This paper describes the PLCs systems in terms of their architecture, their interface to the process hardware, the functionality and the application development facilities they provide. Some attention is also paid to the industrial standards to which they abide their planned evolution as well as the potential benefits of their use.
Ladder Logic is a graphical programming language, initially programmed with simple contacts that simulates the opening and closing of relays. Ladder Logic programming has been expanded to include functions such as Counters, Timers, shift Registers and math operations.
Ladder logic is a method of drawing electrical logic schematics. It is now a graphical language very popular for programming Programmable Logic Controllers (PLCs). It was originally invented to describe logic made from relays. The name is based on the observation that programs in this language resemble ladders, with two vertical "rails" and a series of horizontal "rungs" between them.

SOFTWARE USED
All Control Logix and Compact Logix processors use LogixPro 500 software to
program the PLCs. Admittedly, the software is a bit pricey, but in my opinion, it is
worth it.
Getting The LogixPro 500 Software
If you don’t have access to a PLC, it would be well worth the effort to download the
demo version of LogixPro 500. The demo runs for 90 days, and has some
limitations, but you will be gaining experience with the real thing. Currently, the
