Mitsubishi Electric Software — MELSOFT Suite

Engineering, visualization, and integration tools for industrial automation

The MELSOFT software suite from Mitsubishi Electric is designed to support the entire lifecycle of industrial automation systems — from initial engineering and commissioning to daily operation, diagnostics, and long-term maintenance.

Rather than a single monolithic application, MELSOFT is a structured set of tools, each focused on a specific task: control programming, motion setup, HMI design, SCADA visualization, network configuration, and data integration.

This modular approach reflects real engineering practice: different systems require different levels of complexity, and no single tool fits all applications.

Scalability as a Core Principle

The key concept behind MELSOFT is scalability.
The same software ecosystem supports:

• compact standalone machines
• multi-axis production equipment
• line-level automation systems
• plant-wide visualization and monitoring

This allows engineering teams to grow systems over time without changing tools or redesigning software architecture.

All MELSOFT products are built on Microsoft-based technologies, including OPC and ActiveX.

This ensures a familiar working environment, broad interoperability and straightforward integration with third-party tools such as Microsoft Excel, databases and higher-level industrial software platforms.

Main Functional Blocks

Visualization and SCADA

Visualization and SCADA tools provide real-time insight into machine and process behavior.

Depending on system scale, users can select lightweight HMI environments or full-featured SCADA platforms.

• MX4 SCADA — supervisory control, data analysis, and large-scale visualization
• MX4 HMI — visualization and control for small and medium systems
• E-View — configuration software for operator panels and embedded HMIs

These tools support alarm management, trend visualization, event logging, downtime analysis, and historical data processing — key functions for operational stability and continuous improvement.

Programming and Configuration

MELSOFT provides dedicated programming environments for each major hardware category within the Mitsubishi Electric automation portfolio.

• GX Works2 / GX Works3 — PLC programming for FX, L, Q, and iQ-R series
• MR Configurator2 — servo drive tuning, diagnostics, and waveform analysis
• FR Configurator2 — frequency inverter configuration and monitoring
• GT Designer3 (GOT2000) — HMI screen design and panel setup
• Network Configurator — configuration of CC-Link, CC-Link IE, and industrial networks

All programming tools provide graphical interfaces, multi-language support, and simulation capabilities, allowing testing and verification before commissioning on real equipment.

Communication and Integration

Communication and integration tools enable structured data exchange between Mitsubishi Electric devices and external software environments.

Built on open industrial standards, they support integration with MES, SCADA, and business-level systems.

• OPC servers and drivers for real-time data access
• ActiveX components for custom interface development
• data exchange with Microsoft Excel and database systems
• support for Ethernet, Modbus, and CC-Link networks

Key Advantages for Engineering Teams

• unified software ecosystem across the Mitsubishi Electric automation range
• scalable architecture from small machines to enterprise systems
• compliance with OPC and Microsoft communication standards
• integrated tools for engineering, monitoring, and maintenance
• reduced commissioning time and more predictable troubleshooting

Typical Applications

• process and machine visualization
• PLC, motion, and sequence control programming
• servo system and inverter tuning
• data acquisition and production monitoring
• integration with SCADA, MES, and ERP platforms

How MELSOFT Is Usually Applied

In practice, MELSOFT is not used as a single tool, but as a coordinated environment supporting the full automation workflow.

Engineering teams typically combine:

• PLC and motion programming tools
• HMI and SCADA visualization
• network and communication configuration
• diagnostics and maintenance utilities

This integrated approach helps ensure that automation systems remain maintainable, transparent and adaptable throughout their lifecycle.
