Introduction4:41
Accessing Attached Resources and Setting Optimal Video Resolution2:23

Downloading and Installing the Arduino OPC Server4:17
The Arduino OPC Server is downloaded, installed and then registered on the operating system.
Installing the Arduino OPC Library2:55
The Arduino OPC library comes with the Arduino IDE. The video shows how to locate the library and install it on the IDE.
Downloading and Installing the dOPCDAClient Application2:43
The dOPCDAClient application is an OPC test client application. This will be used for testing of the data communications with the OPC server and the Arduino.
Downloading and Installing the Winlog Lite HMI Application3:13
The Winlog Lite application will be used as the HMI which will act as an OPC client. This will allow for visualization of the OPC data.
Hardware Components1:29
A look at the hardware components used and where to get them.

In this section, we are going to build a full system consisting of the Arduino, OPC Server and OPC Client.
Building the Arduino Sketch - Part 14:30
Building the Arduino Sketch - Part 1
Building the Arduino Sketch - Part 25:10
Building the Arduino Sketch - Part 2
Testing the Arduino with the OPC Server and OPC Client7:01
The sketch is downloaded in the Arduino. The OPC server and the OPC client are then set up and used to test the communication.

The Plan for this Section4:13
In this section, we are going to modify the hardware and software to perform OPC communications over a network.
Modifying the Original Arduino Sketch for OPC Network Communication4:29
The arduino sketch is modified to activate the Ethernet shield in order to implement OPC communications over the network.
Testing the Arduino with the OPC Server and OPC Client7:05
The sketch is downloaded in the Arduino. The OPC server and the OPC client are then set up and used to test the communication.

Requirements

Elementary understanding of the "C" programming language
Basic understanding of elementary electronics
Familiarity with the Arduino Uno prototyping system and it's programming

Description

The Arduino is being used more and more every day for small scale SCADA and Automation projects, due to it's low cost and ease of connecting with various types of I/O devices. In many projects there is a need to connect the controller to a SCADA Human Machine Interface (HMI) application for the purposes of data visualization.

OPC has become the essential de-facto standard for HMI communications with controllers from different vendors. It becomes quite useful, therefore, for an Arduino to be able to communicate with a SCADA HMI application via OPC.

That is what this course teaches you to do!

In this course, you will learn ...

1. How to download and install a FREE OPC server designed for the Arduino.

2. How to program the Arduino so that it is able to communicate with an OPC server via serial and network media.

3. How to use a simple OPC client to test OPC communication with the Arduino via the OPC server.

4. How to configure a simple SCADA HMI to read data from and write data to the Arduino via OPC.

The course has ready-to-go code that you can download as well as detailed wiring diagrams that you can use to build your own automation projects.

Who this course is for:

Electrical Engineers
Electrical Technicians
Electrical Tech or Engineering Students
Process Control Technicians and Engineers
Process Automation Engineers
Programmers working in the Process Automation field
