I wrote a version of this a couple of years ago for technical people with no prior SCADA knowledge or experience. I still see this question posted across the internet consistently. Ignition 8.3 has added additional topics to learn about earlier on to get the most out of Ignition and CI/CD. All of the resources you may need to learn how to develop with Ignition are free and available online. There are minimal barriers to learn Ignition right now and a growing demand for Ignition engineers.
Why Learn Ignition? Know Your History
I had more information about the basics of SCADA and the industry in my last post on Reddit, but now most of my thoughts about where the industry is headed and why Ignition is at the cutting edge are in the second half of my presentation on the History of Industrial Automation: History of Industry — From 0.0 to 5.0.
How Can Someone Learn Ignition from Scratch?
It depends. Everyone will start with a different level of understanding about the various disciplines that managing a SCADA system calls upon. Something else to consider is your specific role in the overall organization that you will manage an Ignition system with. You do not need to be a database expert if you are working with a great team of database administrators, but if you are planning to run everything yourself, broad knowledge is necessary.
The short answer to how to learn Ignition is still: develop with Ignition and its related tools and systems.
This can be done by almost anyone due to the free trial and trainings online. In addition to the fundamentals of Ignition there are also many disciplines that you may want to learn in order to resolve problems related to Ignition: Networking, PLC Programming, Security, etc. Depending on your role you could be responsible for only small parts of an Ignition system, and therefore the required level of knowledge per topic mentioned will vary per person.
How Does Ignition Work?
Ignition is a server-based software platform for developing projects using Ignition's OPC-UA server, OPC-UA client, web server, and more features. Ignition is sold to companies through licenses that they apply to the instances of Ignition they are running, but Ignition is free to download and try at any time with the free trial.
Looking at it very simply, Ignition is a Java application that runs Jython for scripting and is developed by Inductive Automation in California, USA. It can be installed on any major OS, or run as a container, and users will interface with the Ignition server and custom-made SCADA applications using web pages or native launcher applications.
As of 8.3 the gateway configuration is trackable as plain JSON instead of inside the internal SQLite database, and Ignition projects can be more easily version controlled.
Learning Ignition
Soft Prerequisites
Know your Operating System — You should be able to use your preferred Operating System well. Know how to complete actions like: restarting a service, accessing logs, and altering restricted files. Most Ignition documentation and references you will find will not explain the nitty gritty details of what OS buttons to click to open a file as an admin, or what to search for in order to accomplish standard tasks like opening a terminal.
Translate from or read English — Currently most resources you will find related to Ignition will be sourced in English, so translating or being able to understand English is helpful.
Getting Started
Ignition can be downloaded and installed for free. Ignition has a repeatable 2 hour trial timer that you reset by logging into your Ignition Gateway webpage when it expires. During trial mode you can design as if you had a full license for any native Ignition module or feature. When the timer runs out, device connections stop pulling data, Perspective sessions and Vision clients will not launch, and other features will halt. The Designer keeps working the whole time, so you can keep building and reset the timer when you need a feature that is waiting for the reset.
Download Ignition from Inductive Automation
When installing leave everything as default, select the Standard edition during commissioning, and then set a username and password that you will remember. I don't recommend using the Quick Start project if you are following a structured guide or course like Inductive University, but it won't cause any problems for a testing server.
If you are comfortable with Docker, you can run your practice gateway as a container instead of installing it.
Start Watching Inductive University (IU) and Build a Project
Once you have your Ignition server installed, you can start to learn how to operate it using the free tutorial library and an example project specification like the Ignition Design Challenge: inductiveuniversity.com & Ignition Design Challenge.
Most of the major Ignition features and settings are documented in the IU, so following along in your Ignition server with the videos will help you learn the terminology and features. Make sure you are watching the 8.3 version of each course, since IU keeps older versions available and the gateway interface was redesigned in 8.3.
The Design Challenge project can help narrow the topics to learn about as you move through different prompts or features. Consider starting with some early videos about the basic platform, designer, and simple actions like creating resources and taking backups. Once familiar with the installation proceed with developing the project from the Design Challenge. Whatever you watch, do it with the Designer or Gateway Webpage open on a second monitor and build along.
Install a Database and Use the User Manual
Many Ignition systems interact with SQL Databases, and there are free versions you can download and connect to Ignition for testing. PostgreSQL is what I would install today. You can use the Ignition User Manual documentation on how to install for most major database options: Installing PostgreSQL.
Use the Ignition User Manual documentation as much as possible, the user manual has many examples and will include information that answers the majority of beginner questions. For example, people sometimes ask how to simulate OPC data in Ignition which can be done natively with a Programmable Device Simulator.
Finish IU and Build More Projects (and Eventually Integrate with Git)
Inductive University has a credential course that includes challenges after sections of videos. Complete all the main videos and challenges to reach 100% on the 8.3 version.
Once you have completed Inductive University you can work on a more advanced design specification via the Gold certification practice test prompts, which Inductive Automation publishes as part of the study guide: Gold Certification practice test prompts. If you are interested in earning the certifications review the information on the same website as the study guide and design challenge.
Once you are comfortable with the standard development of Ignition, add a code editor into the mix like VS Code and start tracking the system in a Git repo.
Learn to Version Control Ignition
The database connections, OPC connections, tag providers, and identity providers that used to be locked inside the internal SQLite database are now JSON under data/config, sitting next to your projects.
The practical result is that you can put a gateway under version control the same way you would any application, and compare versions over time. It also means secrets management is now performed in a more comprehensive way where resources reference a secret by name instead of carrying the value.
Because that configuration is on disk, an Ignition system can go through the same pull request review and automated deployment that IT and consumer software products are known for. 8.3 also added deployment modes, which let one set of resources run against different databases and connections in staging versus production without maintaining two copies of the project, and the environment picks the mode rather than the project choosing for itself.
A straightforward way to practice this while learning is to make a change in the Designer or the Gateway web page, then go look at what changed on disk. Inductive Automation has a version control guide for 8.3 here: Version Control Guide.
Working with AI on Ignition
Wait to utilize AI tools while learning basic features, and once using them ensure you scaffold the proper resources to allow them to work within the realm of Ignition. There are pitfalls current models (mid 2026) will make if given no context about Ignition, but many of these issues can be resolved with available community resources and the Ignition documentation itself. Developing base resource examples manually in the designer, and then having AI iterate based on the appropriate syntax of working resources will yield better results than prompting for an Ignition output from nothing. As with any system, learn the basics of what you are working with and identify what resources like MCP servers are available to help you improve the effectiveness of your setup. Tools to start with include:
Learning More
Depending on what role you have, your knowledge of the following topics can vary, but they are all connected to Ignition in some way. I will focus primarily on further resources that an Ignition Engineer at an end-user organization would benefit from. To me, this is someone who has a smaller controls team to work with and has to have fairly broad knowledge of Ignition, but not entirely independent and can rely on more network and control oriented teammates to help with hardware or networking. Other roles will require much more experience with networking, PLCs, ladder logic, and more.
Python
You will learn a little Python in Inductive University but you should learn Python as a standalone language as well. Ignition uses Python as a scripting language that can be added to most resources, and it currently uses Jython 2.7, which means what you are actually coding is Python 2.7 implemented on the Java Virtual Machine. Any feature that is not native to Ignition can often be created using a Python script. To learn more about Python you have a lot of options such as the starting tutorials on: w3schools.com/python (be aware some newer python syntax in most online tutorials won't apply to Ignition 2.7 Python).
SQL and Historians
Similar to Python, you will learn some SQL in Inductive University, but you should still learn more if it applies to you. Assuming you are dealing with a relational SQL database then the SQL section of W3 schools is a good gauge of general information you will need for SQL related Ignition work: w3schools.com/sql
8.3 added a choice around tag history that is worth understanding once the basics of SQL are covered. History can go into the new built-in Core Historian, which uses QuestDB and is purpose-built for timeseries data, or into your own relational database with the classic SQL historian. The deciding question is usually whether anything outside Ignition needs to read that history directly.
Containerization
Using Docker containers, or an equivalent, speeds up the development and testing of Ignition systems and makes it easier for large teams to work together by reducing the possible conflicts related to environments. Once developing with a code editor like VS Code you will want to use containers for testing and validation rather than a VM or local install. There is an IU elective study that introduces Ignition with Docker here: Ignition with Docker.
More Ignition Resources
With Ignition experience, SQL, and Python you can work on and understand more complex projects. You could complete the practice project design test, work on more custom projects, and you can also reverse engineer examples from the Ignition Exchange: inductiveautomation.com/exchange
The Exchange is a collection of Ignition community resources and includes examples of larger demo projects. Once you are familiar with Ignition you can also learn from posts on the Inductive Automation forum, which remains the best place to find out why something does not work: forum.inductiveautomation.com
Networking
Networking matters when connecting Ignition to PLCs, to client panels, etc. Ignition can exist in the Cloud and would need to have encrypted network traffic. Since OT is often older and potentially insecure, more complex networks often form around PLCs and networking can become complicated. Identify what kind of networking knowledge and skills would benefit you most and try to research them ahead of time. When trying to bridge the potential organisational gap between IT and OT, approach everyone with compassion and seek to inform.
PLCs
Ideally you know how much you will need to be interfacing with any PLCs in your work. Ignition has drivers for the most common devices, but when it comes to the actual hardware or ladder logic look for learning resources elsewhere — for example the pinned post of the r/PLC subreddit.
HMI Design
In certain industries the efficiency of your user interface is as important as the underlying controls. Learn about High Performance HMI Techniques for your industry. Find example projects online that people have shared on websites like YouTube for more examples. Research what ISO standards you may need to comply with in your industry.
Security
Similar to networking, security is a large discipline that is important and ideally involves many people working together. Inductive Automation keeps resources related to Ignition security on their website and in the docs: Ignition Security Hardening Guide
Mobile Design, HTML, CSS
In the Perspective visualization module you can develop for mobile applications using a tech stack that utilizes CSS/HTML5. Developing for mobile use compared to a large panel screen requires some adjustments. There is value in learning about front-end UI/UX design practices generally related to mobile design in addition to maintaining high performance HMI techniques. Once again, W3 schools has a CSS section if you want to learn the fundamentals of CSS itself. Another way to practice is developing with flex and breakpoint containers in Ignition and trying to replicate real mobile websites.
