Schneider Modicon Quantum Series PLC Programmable Logic Controller Manual

This is the CPU model list of Schneider Modicon Quantum series PLC (Programmable Logic Controller), which belongs to the core equipment of industrial automation control and is used for logic control and data processing in factory production lines, power, municipal and other scenarios. It is classified and disassembled as follows:

1、 Family positioning: the backbone of industrial control

Modicon Quantum is Schneider's flagship series for medium to large industrial automation, featuring high reliability and strong scalability. It supports hot standby redundancy (dual CPU backup, seamless fault switching), multi bus expansion (Modbus, Ethernet/IP, etc.), and can operate like an "industrial brain" to coordinate motors, valves, and sensors in factories, adapting to:

Process industry (petrochemical, power): control the temperature/pressure of the reaction tower in the refinery and the start stop of the power plant generator set;

Discrete manufacturing (automotive, electronics): robot collaboration for automotive assembly lines, semiconductor wafer handling control;

Municipal engineering (water treatment, subway): sewage treatment plant aeration tank logic, subway signal interlocking.

2、 Model rule: The suffix hides the "control password"

The model format is 140CPUxxxx, with a combination of suffix numbers/letters, corresponding to performance, functionality, and scene adaptation:

Typical scenarios of core differences in model format

140CPU1110 Basic Type (Small Memory+Basic Computing) Small Production Line (Food Packaging) Single Machine Control

140CPU65150 medium configuration (larger memory+multitasking) automotive welding line (multi robot collaboration)

140CPU65260 high-end model (supports hot standby redundancy+high-speed bus) petrochemical DCS system (dual CPU ensures safety)

140CPU67600 flagship model (supporting F-series expansion+advanced algorithms) nuclear power reactor control (millisecond level logical operation)

140CPU67160S security enhanced (S=SIL3 security certification) pharmaceutical factory clean area (compliant+highly reliable)

140CPU1110C Customized Communication Type (C=Integrated Specific Protocol) Smart Grid (Modbus RTU Multi Site Communication)

3、 Value: The Irreplaceability of the 'Industrial Brain'

Stable production line "essential": The cost of replacing PLC in large factories is extremely high (such as in automobile factories, where production losses exceed 100 million). The Quantum series relies on ten years of stable operation (hardware redundancy+software fault tolerance), and is used for core control in 70% of petrochemical/automotive production lines worldwide.

Compliance certification "moat": Models with the S suffix that have passed SIL3 safety certification (the highest international safety level) must be used for pharmaceuticals and nuclear power, and ordinary PLCs cannot enter.

Ecological compatibility "old capital": Schneider has provided Quantum with a huge library of expansion modules (digital I/O, analog acquisition, security modules). Old engineers can write ladder diagrams, while new engineers can seamlessly connect. Changing systems is like "starting over from scratch", and enterprises dare not move.
