1.2 Suggestions for Transition from the AnS/QnAS (Small Type) Series to
the Q Series

1.2.1 Advantages of transition to Q series

(1) Advanced performance of equipments (Tact time reduction).
The Q series includes faster operation processing speed, faster bus speed and dual processors of
Super MSP (MELSEC SEQUENCE PROCESSOR) and general-purpose processor to provide over 5
times more efficient processing than the AnS/QnAS series. This realizes more advanced performance
of equipments.
(2) Compact control panel and space saving
Comparing to the AnS/QnAS series, the Q series requires 60% mounting area, which allows installing
compacter control panel.
(3) Improved maintainability
(a) The high-speed program ports (Ethernet port, USB port, and high-speed serial port) enable the
program reading/writing time to be greatly reduced, resulting in improvement of on-site
maintainability.
(b) The Universal model QCPU does not require the ROM operation because the program memory
is the flash ROM.
(c) As large files can be managed, it is possible to store conventional programs as correction
history in memory.
(4) Easy support for information systems
The Web server module, MES interface module, and high speed data logger module can perform
remote monitoring of programmable controller CPUs and perform data collection for quality control and
traceability. Information can be easily gathered from the factory using a Web server module once
transition from AnS/QnAS series to Q series has been completed.
