The 140CPU65260 is a Unity Processor CPU Module from the Modicon Quantum automation platform, manufactured by Schneider Electric. It serves as the central processing unit for Programmable Logic Controller (PLC) systems in various industrial automation applications.
English Description
The Schneider Electric 140CPU65260 is a Modicon Quantum Unity processor module. It's designed to be the "brain" of a Modicon Quantum PLC system, responsible for executing user logic, managing I/O, and handling communications. This module was a key component in a platform designed for high-availability applications in sectors like petrochemicals, metallurgy, cement, energy, and water treatment.
Key features and characteristics of the 140CPU65260 include:
Processor Type: It is a Pentium-based Unity processor (without an arithmetic coprocessor).
Clock Frequency: Operates at 266 MHz.
Memory:
Internal RAM: 3072 kB (3 MB)
Expandable Program Memory: Up to 7168 kB (7 MB) with a PCMCIA card (in the upper slot).
Expandable File Storage: Up to 8 MB with a PCMCIA card (in the lower slot).
Communication Ports: It features multiple integrated communication ports:
One Modbus Plus (SUB-D 9 female connector for RS-485 network).
One Ethernet TCP/IP (RJ45 connector, supports router functionality).
One Modbus (RJ45 connector for RS232/RS485 Modbus/ASCII).
One USB port (reserved for programming PC).
I/O Capacity:
Discrete I/O: Up to 8000 inputs and 8000 outputs per Modbus Plus distributed network. Unlimited for local racks (up to 26 slots max) and Ethernet remote I/O (up to 31 drops of 28 slots max).
Analog I/O: Up to 500 inputs and 500 outputs per Modbus Plus distributed network. Unlimited for local and Ethernet remote I/O.
Supports up to 1984 remote analog I/O.
Rack Support: Supports 2 local racks. Can manage up to 63 distributed I/O stations per Modbus Plus network and up to 31 remote I/O stations (e.g., S908 remote I/O, Ethernet Quantum remote I/O, Ethernet X80 remote I/O).
Application Structure: Supports various tasks including:
1 cyclic/periodic master task.
1 periodic fast task.
128 I/O interrupt tasks.
128 general interrupt tasks.
32 timer interrupt tasks.
4 auxiliary tasks.
Performance: Can execute approximately 10.28 Kinst/ms (100% Boolean) or 10.07 Kinst/ms (65% Boolean and 35% numerical).
Bus Current Requirement: 2760 mA.
Diagnostic Functions: Includes built-in diagnostics for RAM, user logic, and processor upon power-on and during runtime.
Local Signaling: LEDs for Ethernet activity (green) and Ethernet collision (red).
Security Vulnerabilities: It's important to note that firmware versions V3.5 and earlier contained hardcoded backdoors, which have since been addressed in later firmware updates (V3.30 and higher require Copro version 5.8). Users are strongly advised to update to the latest firmware.
Product Status: This model was discontinued on December 31, 2018, with the end of service scheduled for December 31, 2026.
