(3) High-speed processing
High speed processing has been achieved.
Basic model QCPU
High Performance model QCPU
Process CPU
Redundant CPU
Universal model QCPU
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 The Q01CPU is used without using SB and SW, and the MELSECNET/H network module is mounted on the main base
unit.
(b) High Performance model QCPU, Process CPU, Redundant CPU or
Universal model QCPU
Access to the intelligent function module: 20µs/word (approximately 7 times
MELSECNET/H link refreshing: 4.6ms/8K words (approximately 4.3 times
*2 These are the values resulted from the following comparison:
• Comparing Q02HCPU with Q2ASHCPU-S1
• Comparing Q25PHCPU with Q4ARCPU
• Comparing Q25PRHCPU with Q4ARCPU
