The key to getting ahead in the process automation field is to acquire higher value added skills. You have to gain knowledge on subjects like programmable logic controllers, intelligent devices, data communications, and enterprise plant software solutions.
One of the key skills that will make you very valuable is knowing how to connect plant devices to enterprise software such as human machine interfaces and historians.
And to do that you will need to have a practical working knowledge of the technology called OPC and that is what this course will give you.
By the end of this course, you will be able to install and configure OPC software to connect data from plant devices to enterprise software. You will be able to add significant value to your organization or your clients making you a very valuable team member.
And the more valuable you are, the more income you can command.
The reason for OPC - The Eventual (Pre-OPC) Solution
An industrial automation task force is chartered to developed OPC.
An overview of the basics of what vendors had to do to comply with the OPC standard.
OPC follows the client-server model just as in Modbus TCP/IP, and it is also similar to the Master-Slave paradigm in Modbus RS485.
An OPC client can communicate with multiple OPC Servers and vice versa.
Different applications will inevitably represent data using different data types and structures.
We look a solution to the customer problem using OPC technology.
We look at the different types of specifications and their versions since the inception of OPC
Factors to consider when choosing OPC software
Classic OPC uses communication methods based on COM/DCOM, both of which are Microsoft Technologies.
OPC clients and servers exchange data items, and each item consists of a value, quality and time stamp.
We look at the functions of these three OPC specifications.
We look at the function of OPC HDA.
We explore the function of OPC A&E.
A look at the available codes for Quality and what they mean.

I have been working in the fields of Software Development, Software Systems Integration and Process Automation since 1996. In 2003, I stepped out on my own and started working for myself providing software development and systems integration services to small and medium businesses.
I am also associated with a great company called Mora Systems Limited that under the leadership of it's Managing Director has produced innovative and outstanding products and services in the fields of GIS and Cellular based SCADA.
Teaching has always been a passion for me. I have taught at the tertiary level for many years on the subjects of programming, control systems as well as systems integration. In the last few years I found myself incorporating more and more videos into the curriculum with amazing results.
When I heard of uDemy I just could not help but sign up. With teaching in a classroom, you can reach only so many students, but with uDemy you can reach the world! I plan to publish and promote as many courses as I possibly can on the uDemy platform.
