•High-speed, high-accuracy machine control            
To achieve truly high-speed synchronized control between multiple CPUs, a dedicated bus is used, independent of sequence            
program operation. (0.88 ms operation cycle)            
This multiple CPU high-speed communication is synchronized with motion control to maximize computational efficiency.            
Additionally, the performance of the latest motion control CPU is twice as fast as the previous model, ensuring high-speed,            
high‑accuracy machine control.            
            
•Improved production time with ultra-high-speed processing Improved performance!            
As applications are getting larger and more complex, it is essential to shorten the system operation cycle            
time. To achieve this, the ultra high-speed of 1.9ns            
time. To achieve this, the ultra high-speed of 1.9ns (LD instruction) processing enables to realize shorter             operating cycles.
System performance can be improved by reducing            
the overall scan time, preventing any variances            
in performance. In addition to realization of highspeed            
control which is normally associated with            
microcomputer control.            
            
•High-speed, high-precision data processing Improved performance!            
The floating point addition processing speed has            
been greatly increased to 0.014μs to support highspeed,            
high-precision operation processing. Also,            
new double-precision floating-point operation            
instruction have been added to simplify programming            
and reduce calculation errors when implementing            
complex equations.            
            
•Shorter fixed scan interrupt time realizing higher system accuracy Improved performance!            
    Reduced minimal fixed scan interrupt program time to 100μs.            
    High-speed I/O signals resulting in high-accuracy control system.            
            
“•Improved basic functions Improved performance!
  The CPU’s built-in device memory capacity has been increased to a max. of 60K        words.
  Support increasing control and quality data with high-speed processing.”            
            
“•Large data volume at high-speed Improved performance!
Conventionally, continuous access to the standard RAM and SRAM card’s file register area could not be achieved which had to be reflected in the user program.
When an 8MB Extended SRAM cassette is installed in the High-Speed Universal model QCPU,
the standard RAM can be as one continuous file register with up to 4736K words capacity, simplifying the user program.
Even if the device memory is insufficient, the file register area can be expanded easily by installing the Extended SRAM cassette.”            
            
“•SD memory card Improved functionality!
  SD memory card are supported by High-Speed Universal model QCPU allowing easy data exchange between the PC. The SD memory card and Extended SRAM cassette can be used at the same time allowing extension of file registers (with Extended SRAM .”            
            
“•Protect important data with enhanced security Improved functionality!
 A max. 32-character file password can be set *1.
Special characters (*, @, &, etc.) can be used in addition to alphanumeric characters making it harder to compromise the password.”
