In this tutorial we build a flexible and reusable PLC program to control stacklights and pushbutton indicator lights. You’ll learn how to create a single block of logic that can be reused across multiple machines and projects, with support for steady ON, slow flashing, and fast flashing light modes.

This is real-world automation logic used in production machines.

What you’ll learn

• How to control stacklights using PLC ladder logic

• Creating reusable light control code (modular design)

• Implementing steady ON, slow flash, and fast flash modes

• Timer-based flashing logic best practices

• Applying the same code to multiple lights and machines

• Clean programming structure for scalable projects

Learn how to use Offset (GD registers) in GOT2000 to build one reusable HMI screen that controls multiple devices like cylinders, robots, and stations.

In this tutorial you’ll learn:

• What GD offsets are and how they work

• How to create one cylinder control screen and reuse it

• How to navigate between multiple machines without duplicating screens

• How to reduce engineering time and future updates

• Real project example inside GT Designer 3

This is a powerful technique every PLC/HMI programmer should know to build scalable and professional HMIs. Perfect for Mitsubishi iQ-R PLC + GOT2000 users ?

In this tutorial, we dive into GOT2000 scripting and show how to build dynamic warning popups for real machines using tools from Mitsubishi GOT 2000 Series HMIs You’ll learn how to:

• Use scripting inside GT Designer 3

• Trigger warning popups based on PLC conditions

• Display dynamic messages and machine alerts

• Improve operator awareness and safety

• Build reusable popup logic for future projects

A must-know technique for PLC/HMI programmers who want to create smarter, more professional HMIs. ?

In this tutorial, we build a professional Alarm System for your HMI using Mitsubishi GOT2000 and GT Designer 3. You’ll learn how to create a dedicated alarm screen and a scrolling alarm banner in the header that keeps operators aware of machine issues at all times.

What you’ll learn

• How to design a structured Alarm Screen

• Creating a scrolling alarm banner in the header

• Showing active alarms across all screens

• Organizing alarms for real industrial machines

• Improving operator awareness and usability

• Building reusable alarm architecture for future projects

This is a must-have feature for any real automation project and a big step toward building production-ready HMIs.

In this tutorial, we learn how to create and use Labels (Tags) in Mitsubishi Electric GX Works3 and import them directly into GT Designer3 for fast and clean HMI development. Using labels instead of raw device addresses (X, Y, M, D) is one of the biggest steps toward building professional and scalable PLC projects. In this video you’ll learn: ? What PLC Labels are and why they matter

? How to create Global Labels in GX Works3

? Best naming practices for real projects

? How to export and import labels into GT Designer3

? How labels simplify HMI screen development

? Real examples linking PLC tags to HMI objects

This workflow eliminates manual addressing, reduces mistakes, and makes your PLC + HMI projects much easier to maintain. Perfect for beginners and anyone transitioning from device-based programming to modern tag-based development.

In this tutorial, we learn how to use Z Index registers in GX Works3 to dynamically move and access data from multiple memory locations — and visualize/control it from GT Designer3. Z indexers are one of the most powerful (and underused) Mitsubishi PLC features. Instead of writing duplicate logic for every cylinder, station, or robot, you can reuse one block of logic and let the Z register automatically point to the correct data. In this video you’ll learn: • What Z index registers are and how they work

• Indirect addressing and dynamic device access (D, M, X, Y)

• Moving data from multiple locations using a single logic block

• Practical example for moving data

• Connecting indexed data to GT Designer3 HMI screens

• Tips to scale programs without copying logic

This technique is a huge time saver for machines with repeated stations, cylinders, recipes, robots, or any multi-device system. Perfect for Mitsubishi PLC programmers looking to write clean, scalable, and reusable code.
