PRESS RELEASE
Economical failsafe performance:
The new redundant controller technology for the
process industry from Mitsubishi Electric
Mitsubishi Eletric, Hall 11, Stand C 47
Ratingen, 11 April 2005 – Mitsubishi Electric has expanded its
product line for the MELSEC System Q automation platform
with new standard components for configuration of highavailability, redundant controller systems in industrial process technology applications. Mitsubishi is going to present
the redundant system for the first time at the Hannover Messe
2005 trade show.
The central components of the redundant controller system are
two new high-performance processors (CPUs) developed specifically for the process industry, the Q12PRHCPU and the
Q25PRHCPU. The programmable logic controllers have 52 special
process control functions and complement the existing range of
modules. A new power supply unit and the matching backplanes
are also designed for redundant operation.
Failsafe applications are configured by installing the redundant
System Q controller systems in pairs: In normal operation the active controller executes the program and the identically-configured
backup system only copies the process data. The data exchange
takes place via a special tracking cable. If any components of the
system fails the other immediately cuts in and takes over all control
tasks – and the process continues without interruption. The switching time is extremely short, just 22 milliseconds.

The new controller technology gives users an inexpensive entry to
industrial process automation with a selection of individually combinable standard components and powerful functions, including
comprehensive diagnostics and easy replacement of faulty components while the system is in operation. Potential applications
include process automation in aluminium and steel works, cement
and chemicals plants, power stations, water supply plants, waste
incineration plants, sewage plants and even transport and conveyor systems.
A fully integrated system with protection against failures on all levels
can
be
configured
with
Mitsubishi
Electric’s
own
MELSECNET/H network and the company’s MX4 SCADA visualisation software, which is also designed for parallel operation. In
addition to this the system also supports all popular open networks, including Profibus with the FDT/DTM concept (Field Device
Tool/Device Type Manager), which is one of the process technologies of the future.
The MELSEC System Q automation platform is Mitsubishi Electric’s most powerful modular PLC system. Up to four processors
installed on a single main backplane share the work of the control,
motion control and communications tasks. In addition to this you
can also integrate a full-function PC module in the system. Two
motion, ten logic and two PC processors are available, enabling
precise configuration for individual requirements. This is complemented by Mitsubishi Electric’s ranges of both centralised and distributed I/O technologies.
Mitsubishi Electric is soon going to extend this line of products for
the European market with a new microprocessor for programming
process control applications in the high-level, object-oriented C++
language in a real-time operating system.
