Mitsubishi MELSEC iQ-R CPU Module

The Mitsubishi MELSEC iQ-R CPU Module represents the pinnacle of Mitsubishi Electric's programmable controller technology, delivering the fastest instruction execution speed in its class at 2.5 ns per basic instruction — a benchmark that enables real-time control of complex multi-axis motion, process control, and safety functions from a single CPU platform. The iQ-R platform supports a comprehensive range of CPU types under a unified architecture: standard process CPU (R04/R08/R16/R32), C controller CPU (C4 series for C language programming), motion CPU (R16/R32MTCPU for up to 96 servo axes on SSCNET III/H), safety CPU (R08/R16/R32SFCPU for IEC 61508 SIL 3), and redundant CPU for hot-standby applications. All CPU types share the same backplane, power supply module, and I/O cards, reducing spare parts inventory and simplifying system expansion across Saudi industrial facilities.

The R32CPU at the top of the standard CPU range supports 320,000 I/O points, 2,880 kB program memory (120k steps), and 4 MB data memory, comfortably handling the largest Saudi petrochemical batch and continuous process control programs. Its built-in CC-Link IE Field Network (1 Gbps) and Ethernet port (100 Mbps) provide direct connection to FR-A800/FR-F800 drives, GOT2000 HMIs, remote I/O stations, and MES/ERP systems without communication modules. The iQ-R also supports the SSCNET III/H motion network for synchronised servo axis control at 0.444 ms to 3.5 ms cycle times, covering the motion requirements from simple position-and-go to fully synchronised electronic gearing on multi-axis machines.

The MELSEC iQ-R has become the de facto standard PLC platform for Saudi Arabia's most demanding automation projects. Saudi Aramco's gas oil separation plant (GOSP) automation standardises on MELSEC iQ-R for basic process control and safety instrumented system integration. SABIC and SADAF continuous polymer production trains in Jubail deploy iQ-R redundant CPU configurations to achieve six-nines (99.9999%) availability targets. SWCC and MARAFIQ desalination plants use the redundant iQ-R architecture for multi-train supervisory control where unplanned shutdowns incur enormous cost. Vision 2030 giga-project automation systems including NEOM's industrial zone, Ras Al-Khair industrial city, and Qiddiya manufacturing facilities are standardising on MELSEC iQ-R as their primary PLC platform.
