� High-speed, high-accuracy machine control
By simultaneously processing a sequence program and multiple CPU
high-speed communication (operation cycle of 0.88 ms), high-speed
control is achieved. The multiple CPU high-speed communication cycle
is synchronized with motion control, cutting down unnecessary control.
Moreover, performance of motion control is two times faster than the
previous model, allowing high-speed, high-accuracy machine control.

In a 2-axis, multi-CPU system consisting of a programmable controller CPU and
motion CPU, the motion CPU receives the in-position signal from the amplifier of
the first axis. Next, the programmable controller CPU sends a start command to the
second amplifier. This example thus shows the time it takes from the stopping of
motion on one axis until the beginning of motion on a second axis. This time is a
good indicator of CPU-to-CPU data transfer speed.

� Improved production time with ultra-high-speed processing
To correspond with increasing demands for shortening
production time of large-scale, complex systems, the new
model offers the fastest basic operation performance* on the
market: basic operation processing speed (LD) of 9.5 ns.
This means scan time is reduced, improving production time
and processing accuracy.
In addition, the programmable controller can realize
high-speed control which was previously supported by micro
computer boards only.
*As of October 2008
� High-speed, high-precision real data processing
Floating point addition instruction processing speed is greatly
increased to 0.057 s to support high-speed, high-precision
operation processing of various production data.
Also, double precision operation is added to reduce
calculation errors when implementing complex equations.
