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.

Memory structure

The application memory is divided into memory areas physically distributed in the 

internal RAM and on 1 or 2 PCMCIA memory expansion cards (2 PCMCIA cards on 

models 140CPU65150, 140CPU65160, 140CPU65260, 140CPU67060, 

140CPU67160, 140CPU67260, 140CPU67261 and 140CPU67861, and 1 on 

models 140CPU65860 and 140CPU67861):

1 Application data area always in internal RAM. This area is broken down into 

2 types of data, to be used according to the user's habits and preferences:

v Global located data, corresponding to data defined by an address (for example, 

%MW237) with which a symbol can be associated (for example, 

Counting_rejects).

v Unlocated data, corresponding to data defined only by a symbol. This type of 

addressing removes the memory “mapping” management constraints because 

the addresses are assigned automatically.

v DFB unlocated data corresponding to DFB user function blocks. The size of this 

object area is only limited by the size of the internal RAM physical memory 

available.

2 Application program and symbols area in the internal RAM or in the PCMCIA 

memory card (descriptor, executable code for the tasks and application symbols 

database)

3 Constants area in internal RAM or the PCMCIA memory card (constant words, 

initial values and configuration)

4 Area for storing additional data that can be used for distributed applications to 

store information such as production data and manufacturing recipes (only on 

140CPU65150, 140CPU65160, 140CPU65260, 140CPU65860, 140CPU67060, 

140CPU67160, 140CPU67260, 140CPU67261 and 140CPU67861 CPUs)

According to the application memory size requirements, two memory structures are 

possible depending on whether the Quantum CPU has 0, 1 or 2 PCMCIA memory 

expansion cards:

b Application in internal RAM, the application is completely loaded into the CPU’s 

battery-backed internal RAM (2) the capacity of which depends on the CPU model.

b Application in the PCMCIA card, the internal RAM is reserved for the application 

data. The PCMCIA memory card contains the program space (program, symbols 

and constants areas). Certain types of PCMCIA memory card also take the data 

storage area.

The presence of the symbols area with the program area is optional. The fact of 

having the application symbols database on the PLC means that, when it is 

connected to an empty programming PC (with no applications), all the elements 

needed to debug or upgrade this PLC are available

Expansion of the file storage area

With the TSXMRPF004M, TSXMRPF008M file storage memory cards (4096 or 

8192 KB):

b A file storage area can be provided when the application is completely loaded in 

the internal RAM

b Memory space can be freed up for the program when the application is in the 

PCMCIA card

The Unity Pro programming software assists the application designer with 

management of the structure and the occupation of memory space in the 

Quantum PLC.

Protecting the application

Whether located in the internal RAM or in the PCMCIA card, the application can be 

protected with a key switch (see page 1/8 and page 1/9), in order to prohibit access 

to it 

(read or modify program) online in Unity Pro.

PCMCIA memory expansion cards

Unity Pro

Presentation

PCMCIA memory expansion cards make it possible to expand the RAM memory 

capacity of high-performance Quantum CPUs.

Depending on the model, these cards are designed to accommodate:

b The application program, symbols and constants

b The additional application data

b Or both

PCMCIA memory expansion cards

These cards provide three different storage types: 

b Storage of the application: Program, symbols, and constants in a common space 

of 512 KB to 4096 KB: TSXMFPPpppK/M for Flash EPROM memories 

b Storage of the application and additional data, comprising: 

v An application area of 192 KB to 7 MB 

v A data storage area of up to 7 MB for additional data 

The limit between these two spaces is configurable. The configurable cards are: 

v TSXMRPCpppK/M for SRAM memories 

v TSX MCPCpppK/M for Flash EPROM and SRAM memories 

b Storage of additional data, provided by SRAM TSXMRPF004M, TSXMRPF008M

4 or 8 MB memory cards

These cards use two technologies:

b Battery-backed SRAM

Used particularly in the application program design and debugging phases. 

These cards provide:

v All of the application's transfer and modification services in online mode

v Additional data storage

The memory is protected by a removable battery built into the PCMCIA card. 

A second auxiliary battery is present to enable the main battery to be replaced 

without loss of data.

b Flash EPROM

Used when debugging of the application program is complete. This is used to:

v Overcome battery life restrictions

v Perform one global application transfer

When in use, it is impossible to carry out modifications to the application in online 

mode.

Program modification in online mode

Only those expansion cards in which the program is stored in SRAM memory

TSXMRPCpppK/M allow program modifications to be carried out in online mode.

A user with a CPU equipped with a memory expansion card and who wishes to make 

modifications or additions to the program in online mode must structure the 

application program in several reasonably sized sections.

Racks

Description

Five different rack models are available, with 3, 4, 6, 10 or 16 slots. The rack slots 

are universal (any module can fit into any slot). Almost all Quantum modules are 

designed to fit into a single slot in a Quantum rack (1). 

There are no reserved slots in a Quantum system, although it is recommended that 

power supply modules are fitted in the extreme left slot, for optimum heat dissipation. 

The only limits on the rack are the power available for the modules and the 

addressing space. Any rack can be used in any of the three architectures supported 

by the Quantum platform: Local I/O, remote I/O or distributed I/O. 

In a Quantum system, module addressing and configuration is handled by the 

software. No switches or other hardware components are used.

140XBP0pp00 racks comprise:

1 A metal frame

2 Connectors for module/rack connection

3 Tapped holes for fixing each module

4 Holes for fixing the rack

5 Earth terminals for earthing the rack

Rack expansion module

The 140XBE10000 rack expansion module enables I/O in an adjacent “secondary” 

rack to communicate with the CPU or RIO drop in the “primary” rack via a specific 

communication cable. An expansion module must be installed in each rack. The 

extension cable provides all the signals necessary for data transmission between the 

two racks. A single rack expansion module can be added to each rack.

The rack expansion module has the following flexible characteristics:

b The same 140XBE10000 rack expansion module is used for both “primary” and 

“secondary” racks. A rack expansion system consists of two 140XBE10000 rack 

expansion modules and one cable, available in 1, 2 or 3 m lengths.

b The system can use any Quantum power supply module. Each rack can have a 

different type of power supply module.

b Loss of power in the “secondary” rack will not shut down the entire drop. 

Only those modules located in the “secondary” rack will lose power.

b Rack expansion modules can be placed in any slot in the rack and do not 

necessarily have to be placed in corresponding slots in the “primary” and 

“secondary” racks.

b The rack expansion module is not recognized by the configuration software.

It will appear as an unfilled slot in the I/O map.

b All rack sizes are possible.

b The rack expansion module supports local I/O and remote I/O (31 drops).

b Expansion racks can take all discrete and analog I/O modules and also 

high-speed counter modules.
