Tutorial: C# OPC UA Client

 Halo teman2 inovator!

Pada tutorial kali ini kita akan belajar bagaimana membuat aplikasi sederhana untuk membaca data dari sebuah OPC UA Server, artinya kita akan membuat sebuah aplikasi OPC UA Client. Kita akan menggunakan Visual Studio 2022 dan bahasa C# dengan tipe aplikasi Desktop Windows Form atau bisa disingkat WinForm. 

Aplikasi OPC UA Server yang akan kita gunakan ada 2 macam, yaitu memakai OPCAgentX dari HadiSCADA (silakan lihat di video2 kami sebelumnya jika teman2 belum tahu) dan untuk mensimulasikan fungsi Write kita akan pakai OPC UA Server Simulator dari Integration Objects. 

OPC UA berbeda dengan OPC DA. OPC UA memliki banyak kelebihan. Kekurangan2 pada OPC DA seperti ribetnya konfigurasi DCOM, sudah tidak perlu dipikirkan lagi. Sebenarnya ada beberapa macam koneksi, namun pada tutorial kali ini kita akan menggunakan koneksi Anonymous artinya kita tidak perlu mendefinisikan user authentication apapun, kita hanya perlu parameter IP atau nama komputer dan nama OPC UA Server nya.

Untuk projek kali ini kita akan menggunakan library OPC UA Helper. Kami tidak terlalu mengerti mengenai legalitas library ini, jadi kami tidak bertanggung jawab apabila ada permasalahan terkait legalitas atau apapaun yang menyangkut hukum. Disini kami menunjukan tutorial untuk tujuan pembelajaran saja.

Untuk membaca data dari sebuah OPC Server, ada 2 metode yang bisa dilakukan. Pertama adalah metode Read dan yang kedua adalah metode Subscription. Metode Read butuh triger manual untuk membaca data bisa dari penekanan tombol atau bisa dikombinasikan dengan objek Timer untuk melakukan Read setiap interval waktu tertentu, metode ini disebut juga metode Polling. Sedangkan metode Subscibe atau Subscription dia tidak perlu triger manual, setiap kali ada perubahan value di sisi server akan dikirim pemberitahuan ke sisi client. 

Baik metode Polling ataupun Subscribe masing2 punya kelebihan dan kekurangan masing2. Silakan teman2 coba2 sendiri dan temukan metode yang paling pas untuk sistem yang teman2 punya.

Berikut adalah timeline dari video tutorial kali ini:

00:00 - intro

00:08 - setup OPCAgentX as OPC UA Server

02:17 - create a new project

13:41 - test Connect

16:05 - test Read value

16:26 - Write value

21:12 - Subscribe

Demikian yang bisa kami sajikan kali ini, semoga bermanfaat. Terima kasih dan Salam inovasi!

Tutorial: C# OPC UA Server

Welcome to the tutorial on creating an OPC UA Server application using C#!

OPC UA (Open Platform Communications Unified Architecture) is an industry standard for communicating and exchanging data between different devices and systems. In this tutorial, we will learn how to create an OPC UA Server application using C# language.

The OPC UA Server application we will create will be able to receive requests from OPC UA clients, send requested data, and provide additional functions such as creating and deleting nodes. By the end of this tutorial, you will understand how OPC UA Server application works and be able to apply it to different IoT and industrial automation projects.

Let's get started!

00:00 - intro

00:08 - download OPC UA Helper

01:31 - test with OPCAgentX

03:24 - change Server name

05:23 - change Server port

06:17 - create new Folder & Tags

09:15 - change Application name

09:42 - change Form icon

11:19 - change App file icon

Thank you!

Tutorial: OPC DA Client - C# WinForm

 Hello innovators!

Welcome to this tutorial on how to create an OPC DA client application. OPC (OLE for Process Control) is a widely-used industrial automation protocol that enables communication between various automation systems. In this tutorial, we will be creating a client application that can connect to an OPC DA server, read and write data.

Before we begin, you will need to have the following installed:

+ A development environment : Visual Studio 2022

+ The OPC DA Automation Wrapper Library : watch this video https://youtu.be/KNxQExjK_CQ

+ The OPC Server/Simulator : watch this video https://youtu.be/a0WNkViknoo

+ other OPC Client application for comparation : watch this video https://youtu.be/yaCpdWu4T-A

These are the steps:

00:00 - intro

00:08 - Create a New Project

08:32 - Add Reference

09:11 - Coding / Scripting

22:42 - Testing

24:33 - Compare with OPCAgentX

25:36 - Extra

That's it! With these steps, you can create a basic OPC DA client application that can read data from an OPC server and write it. From here, you can build on this foundation to create more complex and powerful client applications that can fully leverage the capabilities of the OPC protocol.

Thanks, and have a nice day!

Download and install OPCDAAuto.dll

Hello innovators! 

Before we start to build an OPC DA Client application, we need to install the OPC DA library first. This video shows you how to install OPCDAAuto.dll on your Windows system. 

This step is important because the library is not available on NuGet. And the OPC Foundation does not publish this one on the website any more.

So, make sure that you successfully install the library, because in the next tutorial we will use it to create an OPC DA client application.

Here are the steps:

1. download OPCDAAuto.rar from this link: 

https://mega.nz/file/IyJgkZYL#z7qf0ZjR6QKSy7BkQjKtkz_LJT4w4XcGsbYJDcMkyoc

2. extract the file

3. Copy file OPCDAAuto.dll and if your Windows is:

3a. 32-bit then Paste to C:\Windows\System32

else

3b. 64-bit then Paste to C:\Windows\SysWOW64

4. open Command Prompt, and if your Windows is:

4a. 32-bit then type: cd C:\Windows\System32

else

4b. 64-bit then type: cd C:\Windows\SysWOW64

5. type: regsvr32 OPCDAAuto.dll

done!
