Comparison with Competitors
Due to the ultra-fast processing speed, there's no need to
consider the processing time when programming.
* Executed instructions means the average number of instructions executed in 1
µs
by PLC.
Why is high-speed processing necessary?
•
To carry out complicated calculations (with
application instructions) quickly
•
To stabilize mechanical control of higher
speed for higher productivity
•
To allow human-interface and diagnostic
programs to be enhanced, thus providing an
easier interface for the operator
•
To reduce unstable actions during each scan
time by network servicing
