How to choose the right PLC for industrial automation
Selecting the right Programmable Logic Controller (PLC) is crucial for ensuring the success of your industrial automation system. Whether you’re managing a small process or a large-scale industrial operation, the right PLC can improve efficiency, reliability, and scalability. Mitsubishi Electric Factory Automation offers a range of powerful and flexible PLCs to meet diverse automation needs.




Key Factors to Consider When Choosing a PLC
Key Factors to Consider When Choosing a PLC
Application Requirements
Understanding your application needs is the first step in selecting the right PLC. Consider the following:
- Process Complexity: Does your application require simple ON/OFF control or advanced processing capabilities?
- I/O Requirements: How many input and output points do you need, and what types (digital, analog, or special functions)?
- Speed and Performance: Do you require high-speed processing for motion control or real-time data acquisition
PLC Type and Size
PLCs come in various sizes and configurations. Choosing the right type depends on your control system’s scale and complexity.
- Compact PLCs: Best for small to medium automation tasks. Example: Mitsubishi Electric FX5U Series, offering high performance in a compact design.
- Modular PLCs: Ideal for complex and scalable systems. Example: Mitsubishi Electric iQ-R Series, providing advanced networking and security features.
- Rack-Based PLCs: Suitable for large industrial applications with extensive I/O and communication needs.
Communication and Connectivity
Modern industrial automation relies on seamless connectivity. Look for a PLC that supports:
- Industrial Protocols: Ethernet/IP, Modbus, Profibus, CC-Link, and more.
- IIoT and Cloud Integration: Mitsubishi iQ-R Series supports advanced networking, allowing real-time monitoring and data exchange with MES/SCADA systems.
- Remote Access: Ensuring remote diagnostics and troubleshooting capabilities.
Scalability and Future-Proofing
Your PLC should support future expansion as your automation needs grow. Mitsubishi Electric’s iQ-R Series offers a scalable platform with enhanced cybersecurity, ensuring long-term reliability.
Software and Programming Environment
Ease of programming is key to efficient PLC implementation. Mitsubishi Electric provides GX Works3, an intuitive software environment that simplifies programming, diagnostics, and maintenance.
Durability and Environmental Factors
Consider the operating environment:
- Temperature, humidity, and vibration resistance
- Ingress protection ratings (IP ratings) for harsh industrial conditions
- Compliance with industry standards (e.g., IEC, UL, CE)
Industry-Specific Considerations
Different industries have unique automation requirements that influence PLC selection. For instance, the food and beverage industry requires PLCs with hygienic design and fast response times to ensure precise processing and compliance with safety regulations.
In the automotive sector, high-speed motion control and seamless integration with robotics are essential for assembly lines. Water and wastewater facilities need PLCs with robust environmental protection and remote monitoring capabilities for managing distributed assets.
Mitsubishi Electric PLCs cater to a wide range of industries, offering specialised features that enhance productivity, safety, and regulatory compliance
Cost vs. Performance Balance
While cost is a factor, selecting a reliable, high-performance PLC like Mitsubishi Electric’s FX5U or iQ-R Series ensures better long-term ROI by reducing downtime and increasing efficiency.
