Redundant control is an essential requirement for many industries where downtime cannot be
accepted for reasons of cost, interruption to service, equipment damage, safety or regulatory control.

EXAMPLE

Industries where this new system capability is targeted include:

Environmental (refuse incineration, emissions control, desalination, etc.)

Steel (continuous casting, rolling line furnaces, annealing furnaces, etc.)

Chemical (Polymerization, temperature control, blending, mixing, etc.)

Pulp and Paper (conditioning, drying, finish, etc.)

Cement (crushing, kiln control, dust control, etc.)

Water treatment (filtration, pump control, chemical dosing, etc.)

Semiconductor (slurry delivery, gas recovery, wafer handling, etc.)

Material handling (airport baggage handling, conveyors, sorters, etc.)

KEY FEATURES OF THE  Q SERIES REDUNDANT CONTROL SOLUTION INCLUDE:

Triple level redundancy: dual redundant processors, dual redundant networking and hot swap capability to insure maximum process uptime.

Automatic, user defined synchronization of process data between redundant processors, insuring "bumpless" transfer of control.

Dual redundant network capability allows deterministic performance up to 25Mbit/s between controllers and I/O.

Redundant power supplies prevent failure through power loss.

Redundant Ethernet communications insure continuity of communications to SCADA systems (such as Mitsubishi's MX-WORX) after switchover.

No special hardware required beyond redundant processors; reduces cost of ownership as standard Q Series parts can be used on both regular and redundant Q systems.

Redundant CPUs are physically separate, allowing offline CPUs to be serviced without interrupting the process.

Full support using Mitsubishi's established programming & maintenance system, GX Developer; all Mitsubishi controller systems, regardless of type, may be programmed & maintained by the same tools.

Automatic program updates between both CPUs simplifies maintenance

Extremely compact size minimizes panel space.

Extremely high performance; switchover times in the 10s of milliseconds.
Since its launch, the Q Series Automation Platform has received an enthusiastic welcome from the global automation market, with significant installations at both large end user locations, and a widespread OEMbase.

Mitsubish expects the Redundant System to further increase the impact of the Q Series Automation Platform
on the global automation market for those industries where redundant control is an essential requirement.
