Mitsubishi Electric's Q Series Automation Platform originated the concept of a multidisciplinary controller that addressed the challenges of trying to integrate separate types of automation such as PC based, motion, sequence and process on the same system.

Q Series stands apart from conventional PLCs. It is a new, multidisciplinary automation platform addressing needs of OEMs and end users scalable across the general scope of automation applications from smaller to very large systems. While PLCs are typically limited to sequence control, Q Series offers a broad spectrum of different automation capabilities. We refer to it as an "automation platform", as sequence control is just one of its many capabilities. It is equally capable of process, sophisticated motion and open, PC based control, either individually, or simultaneously. Hence Q Series is much more than just a PLC.

The Q Series Motion Controllers meets your need for higher performance and smaller size, all with high-speed motion control! Ideal for small to large scale applications with up to 96 control axes. Various motion controller operating system software packages are also available. With increased high-speed motion, flexibility and compatibility with the Q Series PLC CPU, the Q Series Motion Controllers are the best choice for next-generation motion control technology!

The QnPRH is Mitsubishi’s most sophisticated controller system, and represents the top end of the Q Series Automation Platform line. It offers Tri-Level Redundancy ™ which insures complete immunity to process interruptions caused by power or system failures. This is achieved by using a fully redundant architecture that duplicates processors and network links. Hot-swap capability provides the third level of redundancy. The QnPRH is rounded out by a full complement of process control capabilities.

The QS is an IEC 61508 SIL 3/EN 954 Category 4 certified Safety PLC suitable for all critical safety applications. It is complemented by the open CC-Link Safety device level network, which is also SIL 3 certified for the networking of vital safety devices, such as emergency stops, light curtains and pressure mats.
