OMRON PLC

Today we are going to start OMRON PLC

Omron Corporation is kyoto based company. Omron was established by Kazuma Tateisi in 1933 (as the Tateisi Electric Manufacturing Company) and incorporated in 1948. The company originated in an area of Kyoto called "Omuro (御室)", from which the name "OMRON" was derived. Prior to 1990, the corporation was known as Omron Tateisi Electronics. During the 1980s and early 1990s, the company motto was: "To the machine the work of machines, to man the thrill of further creation".

Omron's primary business is the manufacture and sale of Industrial Automation components, equipment and systems.

Omron Oilfield & Marine is a provider of AC and DC drive systems and custom control systems for oil and gas and related industries.(Source: Wikipedia)

There are various models of PLC but we study with Basic PLC to understand program and its functions better. Below is the description of OMRON model:

Software: CX programming for CP1E

Manufacturer: OMRON

Communication port: USB

Communication Driver: CX programmer host

Series: CP1E-N20DR-D

If you get trouble in installing or connection you can send your queries on my mail.
