Implementing full safety control on small, cost-sensitive equipment can be complex. You want high safety standards without the burden of complex programming. The MELSEC iQ-F Series safety extension modules are designed to easily implement safety control for small-scale equipment.

• No programming required: these modules provide safety control without the need to create a program.
• Pre-built programs: simply select one of the nine built-in programs using a rotary switch.
• Full compliance: the modules are compliant with international safety standards EN ISO 13849-1 Category 4 PL e and IEC 61508 SIL 3.
• Easy monitoring: All safety statuses can be monitored in the PLC as non‑safe data, enabling quick and informed reactions.

Looking for a quick, code-free way to meet safety standards on small equipment? Simply connect MELSEC iQ-F Series safety extension modules with the CPU module that performs safety control, enabling both general and safety control in a single system.

For small- to medium-scale systems, an over-engineered safety PLC is costly and inefficient. You need a powerful, space-saving and easy-to-expand solution. The compact MELSEC‑WS safety controller is ideal for such tasks. It is compliant with standards EN ISO 13849-1 Category 4 PL e and IEC 61508 SIL 3 and addresses critical response time challenges with its innovative technology.

• Rapid response: features a fast shut off function that achieves an 8 ms response time regardless of the CPU, helping you shorten safety distances.
• Scalable design: its compact base can be expanded up to 144 I/O points, accommodating growing safety needs.
• Easy diagnostics: MELSEC-WS safety controllers monitor internal status and error history, making troubleshooting straightforward.
  

Complex wiring and the use of separate engineering environments for general and safety control can create significant challenges. The MELSEC iQ-R Series addresses these issues with its Safety CPU (R□SFCPU-SET), fully compatible with the iQ Platform. This integrated concept enables general and safety programs to operate within a single controller, greatly simplifying system architecture.

• Integrated control: achieve integrated general and safety control, executing both programs on the same controller. This minimizes hardware complexity and communication overhead.
• Highest compliance and wide application: the Safety CPU is certified for the highest standards, PL e and SIL 3 (Category 4). It is a recommended solution for medium- to large-scale control for the production line and distributed system.
• Useful diagnostic tools: the MELSEC iQ-R Series includes maintenance functions like ‘Event history’ and a ‘Diagnostics’ window that provide detailed information on the cause of the failure and remedial measures, shortening downtime.
• Efficient engineering: use the common engineering platform, GX Works3, where general and safety programs are contained within the same project folder, using common labels for data exchange.
• Easy integration: EnablesSafety over Network and further reduces cabling efforts, allowing easy integration of all CCLink IE TSN & Field safety devices.

Human Machine Interfaces (HMIs) are essential for monitoring safety status and diagnosing issues, directly on the production floor. GOT HMIs panels share information on the production floor and monitor the safety status of equipment, including errors. They can be used for centralized on-site monitoring and can provide remote access and diagnosis, such as setting parameters and alarm diagnostics for servo drives.

On-machine insight:

• Clear & simple: HMIs process signals and present them as simple schematics or information on a full color touch screen.
• Full range: Mitsubishi Electric’s GOT HMIs range from 3.7” to 15” in both panel mount and pendant styles.
• Reduced downtime via diagnostics: instantly pinpoint the cause of a safety stop. Mitsubishi Electric’s MELSEC iQ-R controllers feature detailed event histories and diagnostic windows, and our GOT HMIs can graphically display the status and location of all safety equipment.
