(3) Realised high speed processing
High speed processing has been achieved.
The MELSEC Q series base unit high-speed system bus has achieved faster access
to an intelligent function module and link refresh with a network module.
(a) Basic model QCPU
MELSECNET/H link refreshing: 2.2ms/2k words
*1
*1: This is the case that the Q01CPU is used without using SB/SW and the
MELSECNET/H network module is installed to the main base unit.
(b) High Performance model QCPU, Process CPU, Redundant CPU or
Universal model QCPU
Access to the intelligent function module: 20 s/word (approximately 7 times
*2
)
MELSECNET/H link refreshing: 4.6ms/8k words (approximately 4.3 times
*2
)
*2: These are the values resulted from the following comparison:
•Comparing Q02HCPU with Q2ASHCPU-S1
•Comparing Q25PHCPU with Q4ARCPU
•Comparing Q25PRHCPU with Q4ARCPU
