System Q's Process CPUs bring the benefits of standard System Q technology into the process environment, reducing both implementation and long-term running costs. These powerful processors combine standard PLC control with 52 dedicated process control functions, including loop controls with two degrees of freedom (DOF) and highspeed PID control.

Mitsubishi Electric's dual-redundant CPUs bring an additional layer of fault tolerance to the control of a whole system. This results in high reliability: if the main CPU, power supply or base unit fails, a secondary system starts immediately (within 21ms) from the same control point.

For users this has two major benefits: no operational damage due to a single system failure, and production that continues seamlessly.

The System Q automation platform can also be applied to other areas requiring high reliability, e.g. standby network masters, redundant fieldbus (CC-Link) and redundant power supplies for remote I/O stations.

Q Series PLC

The Q Series can utilize a multiple PLC system where multiple high CPUs are loaded on the same main base to manage I/O and intelligent function modules CPU-by-CPU in a control system. The Q Series Ethernet, MELSECNET/H and CC-Link have achieved seamless access beyond the differences in network type and network hierarchy. Data can be transferred between any networked PLCs
