Each programmable controller CPU in the multiple CPU configura-
tion is capable of simultaneously processing multiple CPU high-
speed communication (14k words/ 0.88ms), executing a sequence,
process or motion program, and performing high-speed machine
control. In motion applications, the motion control operations are
synchronized using multiple CPU high-speed communications.
Increase the production rate with ultrahigh-speed processing
Increased program capacity
In order to speed up production data calculations, the floating point
addition instruction's processing time has been reduced to 0.057 .
New CPU models offer ultrahigh-speed basic operation
performance, (LD) of 9.5ns, in response to building demands
for increased system production rates.
In a multiple CPU system (a PLC and a motion controller), with
the in-position signal from the servo amplifier of the first axis
(used by motion controller) as the trigger, the PLC sends a start
command to the servo amplifier of the second axis. The time it
takes for the servo amplifier of the second axis to output the
speed command is called the in-position response time, and
this time is a good indicator of CPU-to-CPU data transfer speed.

Programs are divided into 124 (max.) sub-programs according to categories such as product and process. This facilitates structuring programs into
individual routines. Such structured programs can be highly specialized to enhance visibility for detailed program management. In addition, standard ROM
(4MB max. capacity) enables the storage of device labels and comments for function block and sequence programs to be stored in the PLC CPU.

With the increased speed of basic operation processing
comes scan time reductions, and improvements in process-
ing accuracy. High-speed control (previously only supported
by micro-computer boards) using these PLC CPUs has
become a viable solution.
Calculation errors of complex equations can be reduced
using the newly added double accuracy operation.

The capacity of standard RAM, which can be used as file register, has been increased to store larger amounts of production and quality data. Additionally,
large-capacity SRAM cards are now supported. An 8MB SRAM card can be used as file register for 4086k words (max.) to handle large volumes of data.
