Essential Guide to Programming for Delta HMI302

Introduction

Delta Human Machine Interfaces (HMIs) are powerful devices designed to connect operators with industrial machines and processes. They provide intuitive graphical interfaces for monitoring, controlling, and configuring a wide range of automation systems. Programming Delta HMIs is an essential skill for engineers and technicians who wish to leverage the full capabilities of these devices. This comprehensive tutorial will guide you through the steps of programming Delta HMIs, empowering you to create customized solutions for your industrial applications.

Step 1: Software Installation and Setup

Begin by installing the Delta HMI programming software on your computer. This software is available for download from Delta's official website. Once installed, launch the software and create a new project. The software will prompt you to select the type of HMI you are using. Choose the appropriate model and firmware version for your device.

Step 2: Project Creation and Structure

A Delta HMI project is organized into multiple files and folders. These files include the main script file, communication configuration files, and data files. The main script file contains the core logic and functionality of your program. Communication configuration files define the communication parameters between the HMI and external devices. Data files store variables, strings, and other data used by your program.

Step 3: Programming Language

Delta HMIs use a proprietary programming language called DOPsoft. DOPsoft is a structured text language similar to Pascal. It features a range of commands and functions tailored specifically for HMI programming. DOPsoft allows you to create functions, loops, conditional statements, and other control structures.

Step 4: Variable Management

Variables are used to store and manipulate data within your program. Delta HMIs support a variety of data types, including integers, floating-point numbers, strings, and booleans. You can define variables with custom names and data types. The values of variables can be modified through program code or user input.

Step 5: Screen Design

The graphical user interface (GUI) of your HMI is composed of multiple screens. Each screen can contain a variety of elements, such as buttons, text fields, gauges, and charts. Delta HMI software provides a user-friendly interface for designing and customizing these elements. You can arrange elements on the screen, set their properties, and define their functionality.

Step 6: Communication Configuration

Delta HMIs can communicate with a wide range of external devices over various communication protocols. Common protocols include Modbus, Ethernet/IP, and CANopen. The communication configuration process involves defining the communication parameters and mapping data between the HMI and the external devices.

Step 7: Debugging and Simulation

Once your program is complete, it is essential to test and debug it to ensure it functions as intended. Delta HMI software provides a built-in simulator that allows you to test your program without connecting to an actual HMI. The simulator can identify syntax errors and other issues in your code.

Step 8: HMI Deployment

After successful testing and debugging, your program can be deployed to the Delta HMI. The software will generate an executable file that can be downloaded to the HMI via USB or Ethernet. Once deployed, the HMI will run your program and display the graphical interface to the user.

Conclusion

Programming Delta HMI devices requires a combination of technical expertise and creativity. By following the steps outlined in this tutorial, you will acquire the skills necessary to create customized HMI solutions that meet the specific needs of your industrial applications. Embrace the power of Delta HMIs and unlock their full potential for monitoring, controlling, and configuring your automation systems.
