SYSTEM Q AT A GLANCE

Ever more demanding manufacturing systems, new forms of communication and the need to integrate new technologies are pushing the performance limits of conventional PLC systems.

Mitsubishi Electric's response to these growing challenges is our Q series high-end controllers with advanced multi-processor technology.

In each system, up to four separate CPUs share the processing load of control, motion control, PC and communications tasks.

This brilliantly simple solution brings a dramatic boost in system availability and performance. This means, there's no more need to install multiple PLCs and a network to connect them.

Now you can control multiple applications with a single system using the Q series powerful multi-processor functionality. With its integrated IT technology, MELSEC System Q opens up a wide range of options for worldwide communication.

With its unique design concept and outstandig features MELSEC System Q can rightfully claim to be the controller platform for the future.

Key features include:

All program cycle periods continuously adjustable from 0.5-2.000ms in 0.5ms steps

Self-diagnostics with error history stored in the CPU

Memory expansion options up to 32MB

Support for remote diagnostics and programming (modem, Internet, intranet)

Monitoring of special function modules, online system analysis on screen

All CPUs fitted with integrated Flash ROM

Utility tools enable simple configuration and functional tests of analog and special function modules

Programmable with IEC 1131.3/EN 61131-3 compatible software or (via a PC CPU) in high-level languages like C++ or Visual Basic

Soft PLC available for the PC CPUs
