Modular PLC – PLC control

Reliable control when you need it most

The modular concept

Building on its predecessor, the AnSH, System Q is a control concept that allows users to mix and select the best combination of CPUs, communication devices, specialist control modules and discreet I/O on a back- plane. This allows users to configure systems into what they need, when they need it, where they need it.

Multiple capabilities

Basic and advanced PLC CPUs, specialist motion and process controllers and even PCs can be combined into a single System Q solution with up to four different CPUs. This gives users a choice of control philosophies, programming concepts and programming languages – all from a single platform.

An automation platform for the future

Flexibility and scalability are key design features that enable System Q to truly be a single Automation Platform. Users can apply simple control to an individual machine or integrated plant wide management all from the same hardware base.

Supporting the System Q platform is a suite of software tools enabling easy and comprehensive integration through EZSocket, Mitsubishi’s own middleware. In addition, Mitsubishi also offer software tools that comply with international standards such as IEC1131.3, OPC and Active X. This tremendous flexibility permits users to reduce development time, simplify commissioning, and provide ongoing system maintenance.

Basic PLCs

Not every control application requires the full power of System Q. For example, many machine builders embed control technology into their machines and require small compact designs featuring flexible high-speed operation. System Q’s Basic PLC CPUs offer just this kind of solution, balancing power and performance against cost. A good example of this is the Q00J CPU.

This all-in-one unit provides power supply, CPU and backplane as a single, ready-to-use unit ideal for small systems that still require powerful performance. Other Basic PLC CPU options include the classic modular designs Q00 and Q01, the first steps on the path to the full System Q automation platform.

Advanced PLCs

For advanced machine designs and controlling manufacturing cells, including infrastructure and site-wide management, System Q’s advanced PLC CPUs offer incredible performance and versatility.

Processors are available with a wide range of memory capacities, all of which can be expanded as required. This means that System Q PLCs can support complex programs as well as store large volumes of operation data.

Universal PLC CPUs

These universal PLC CPUs are the latest generation of modular CPUs for the MELSEC System Q controller platform and they are the foundation of the iQ Platform system. They can be combined with the motion, robot and NC CPUs to configure scalable and highly flexible modular automation systems.

Scalable

With the exception of the embedded Q00J CPU, all System Q PLC processors are interchangeable, which means processing power can be increased as applications grow, protecting your investment in infrastructure and hardware.

Multi Processor support

Up to four separate System Q PLC CPUs can be placed in a single system. These can be used to control their own set of dedicated tasks or for sharing the processing and control load, making the total system highly responsive. This provides users with faster, more dynamic control, leading to better production quality and improved production rates.
