3.0 OVERVIEWS

Programmable logic controllers (PLCs) initially appeared in the industry during the 1960s and
had a completely different form than those implemented today, since they were built out of
logical components that only replaced the operation of the auxiliary relays. Nowadays, PLCs
can be either simple or complex, come in a variety of sizes, and are equipped with a wide
variety of extensions or interfaces that fulfill all the type of needs found at factory level, including
the need to communicate with other devices and computers. It should also be mentioned that
there are multiple programming languages for tuning the behavior of PLCs so that they can
match the different programming skills of the end users. This lab activities will uses Siemens
PLC and Logo! Soft Comfort software as showed briefly in following video,
https://www.youtube.com/watch?v=Oi_b50nOMGY. The necessary tools as presented in
