Programmable Logic Controllers MELSEC iQ-R Series

Build faster. Run safer. See more. Mitsubishi Electric’s MELSEC iQ-R unifies high-speed control, motion, functional safety, advanced data logging, and IoT connectivity—helping manufacturers deliver projects faster, operate more efficiently, and make better decisions with real-time data.

The iQ-R platform is designed to lower costs across the entire system lifecycle. By combining advanced engineering tools, hardware compatibility, and intelligent maintenance features, it helps streamline operations and extend equipment longevity. These advantages combine to significantly cut both capital and operating costs while delivering stable, predictable performance.
Key benefits include:

iQ-R Recorder Module – traceability without compromise
Capture all process, motion, and system data every cycle directly in the module—without impacting control performance—and enrich it with AI-driven analysis for smarter decisions.

• High speed logging of all data in the entire system – every cycle
• Synchronized recording across logic, motion and vision data via CC-Link IE TSN for network-level time alignmentWaveform comparison & AI pattern recognition to detect even subtle deviations instantl
• Camera integration for capturing and linking visual evidence directly to process events—ideal for quality inspections and root-cause analysis
• Long-term storage on SD card or via network upload for compliance and historical trend analysis

Seamless OT–IT integration means your machines are not just automated—they’re connected, secure, and ready for the future:

• OPC UA Server – standardized data exchange with MES, SCADA, ERP
• MQTT Support – lightweight, event-driven data push to cloud platforms or local brokers
• MES/DB Direct Modules – log production data directly into databases without middleware
• e-F@ctory Starter Packages – quick-start templates for energy, OEE, and anomaly monitoring – free of charge

The same controller running your line also feeds your dashboards, cloud analytics, and AI engines—no extra gateways required.

With CC-Link IE TSN at its core, the MELSEC iQ-R Series connects seamlessly to the Mitsubishi Electric Factory Automation portfolio:

• Servo systems – MR-J5 drives for high-precision motion
• Inverters – Efficient motor control for pumps, fans, conveyors 
• HMIs – GOT Series for intuitive operation and diagnostics 
• Industrial robots – MELFA robots for assembly, handling, inspection 
• Open IoT Platform GENESIS – Real-time visualization and analytics 
• MELSOFT MaiLab – AI-assisted maintenance and process optimization
• MELSOFT VIXIO – AI visual inspection for quality control 
• Digital Twin simulation (MELSOFT Gemini) – Virtual commissioning and cycle optimization 

This integrated ecosystem allows you to build complete automation systems—from control to analytics—on a single platform, with the flexibility to connect to third-party devices and cloud services.

The MELSEC iQ-R Series offers integrated Functional Safety up to SIL3 / PLe, enabling you to control standard automation and safety logic in a single platform.

• SIL3 / PLe Certified Safety CPUs – Centralized or distributed safety control in the same rack as your standard CPU
• Local Safety Digital I/O – Connect safety devices directly to the CPU for high-speed, deterministic response
• Remote Safety Digital I/O – Extend safety zones via CC-Link IE TSN Safety without compromising cycle times
• Flexible zoning – Stop only the hazardous part of the machine while keeping the rest in operation
• Drive-level safety functions – Integrated over the network (STO, SLS, SS1) to protect operators while minimizing downtime

Why it matters: Functional Safety in iQ-R means less wiring, fewer separate controllers, and simplified programming. Safety and standard control share the same engineering environment (GX Works3), reducing project complexity while maintaining the highest safety performance.
