Modicon Quantum automation 

platform

To the world of Schneider Electric

Presentation

This catalogue presents the range of Modicon Quantum PLCs and includes new 

products, such as CPUs, power supplies and communication modules, which extend 

the field of application of the range in the various standard and safety industrial 

application areas.

With an already wide selection of I/O modules, and an already extensive offer in 

terms of communication on fieldbuses and networks, Modicon Quantum is even 

better suited to the needs of continuous or semi-continuous industrial processes and 

control of large infrastructure sites.

Capitalizing as it does on more than 25 years' experience in redundant processing 

architectures, and fully meeting safety requirements for people, production 

installations and their environment, Modicon Quantum is the ideal solution for 

applications requiring maximum availability in complete safety

Applications

The Modicon Quantum offer is, de facto, inherently designed for high availability 

applications in the areas below:

b Petrochemicals

b Metallurgy

b Cement

b Energy 

b Tunnels

b Airports

b Water treatment

b Mines

b Hydropower

Modicon Quantum automation

Unity Pro standard CPUs

Presentation 

The CPUs for the Modicon Quantum automation platform are based on highperformance processors and are compatible with Unity Pro software. Numerous 

functions are included as standard in Quantum CPUs: 

b Superior scan times and fast I/O acquisition

b Ability to handle interrupts (timed and I/O based)

b Handling of Fast task, as well as a Master task 

b Memory expansion using PCMCIA cards

b Multiple communication ports integrated in the CPU

b Ease of diagnostics and maintenance via the LCD display block on the front panel 

of high-end CPUs

The CPUs offered have different memory capacities, processing speeds and 

communication options.

Protected backed up memory

As standard, the CPUs store the application program in a battery-backed internal 

RAM. This battery is located on the front of the CPU and can be replaced while the 

CPU is running.

A switch enables the application to be made secure against malicious tampering via 

a remote connection. 

To protect the application program from inadvertent changes during operation, the 

CPUs feature a key switch on the front panel to protect the memory. This key switch 

can also be used to start and stop the CPU. The 140CPU31110 CPU only has a 

memory-protect slide switch.

The high-end 140CPU65150, 140CPU65160, 140CPU65260, 140CPU67060, 

140CPU67160, 140CPU67260 and 140CPU67261 CPUs have 2 slots for a 

PCMCIA card:

b An upper slot (no. 0) for a memory expansion card (programs, symbols, constants 

and/or data storage)

b A lower slot (no. 1) for a data storage memory expansion card

Besides the large-capacity internal RAM, the high-end 140CPU65860 and 

140CPU67861 CPUs have 1 slot for a PCMCIA card: 

b One slot for a data storage memory expansion card

Built-in communication ports

Quantum CPUs incorporate, depending on the model:

b Two RS 232 Modbus ports (1 RS 232/485 Modbus port for 140CPU6pppp CPUs)

b One Modbus Plus port

b One TCP/IP 10BASE-T/100BASE-TX Ethernet TCP/IP port (100BASE-FX for 

140CPU67p6p Hot Standby CPUs)

b One USB port for connecting a programming PC terminal for the CPUs

LCD display

Depending on the model, the CPUs have an LCD display (2 lines of 16 characters) 

with adjustable brightness and contrast controls. The keypad associated with the 

display can be used for diagnostics, access to certain configuration parameters and 

starting and stopping the CPU.

Hot Standby redundancy

140CPU67060, 140CPU67160, 140CPU67260, 140CPU67261 and 140CPU67861

CPUs are dedicated to the availability function of Hot Standby applications. They 

have a 100 Mbps Ethernet fibre optic link and the Hot Standby function can be 

diagnosed using the LCD display. 

The 140CPU67261 and 140CPU67861 CPUs are specifically designed for Hot 

Standby applications for which the distance between the two Hot Standby CPUs can be 

as much as 16 km.

Some CPUs have increased capability in terms of memory, number of drops, and 

online functions, etc. See the dedicated description pages for more information.

Quantum application design and installation

Use of these Quantum CPUs requires: 

b Unity Pro Large or Extra Large programming software. This software is 

compatible with the Premium, M580 and M340 platforms.

b Optionally, as required:

v Unity EFB toolkit software for developing EF and EFB function block libraries in 

C language

v Unity Dif software for comparing Unity Pro applications

v Unity Loader software for updating Unity Pro projects
