Modicon M340 automation platform Standard processors, BMX P34 1000, and 
Performance processors, BMX P34 2pppp , manage single-rack or multi-rack PLCPLC 
stations whose slots can be equipped with:
Discrete I/O modules
Analog I/O modules 
Communication modules: Ethernet Modbus/TCP network, AS-Interface actuator/AS-Interface actuator/
sensor buses and RTU (Remote Terminal Unit)
Application-specific modules: counter, axis control and serial link
The five processors offered have different memory capacities, processing speeds, 
number of I/O and number and type of communication ports.
In addition, depending on the model, they offer a maximum (non-cumulative) of:
512 to 1024 discrete I/O
128 to 256 analog I/O
20 to 36 application-specific channels (1) (process counter, motion control and 
serial link, or RTU)
0 to 3 Ethernet Modbus/TCP or Ethernet/IP networks (with or without integrated 
port and 2 network modules maximum)
4 “Full Extended master” AS-Interface V3 actuator/sensor buses, profile M4.0
Depending on the model, Modicon M340 processors include:
A 10BASE-T/100BASE-TX Ethernet Modbus/TCP port
A CANopen machine and installation bus port
A Modbus or Character mode serial link port
Each processor has a USB TER port (for connecting a programming terminal or a 
Magelis XBT GT/GK/GTW, GTW HMI, or STU/STO HMI terminal) and is supplied 
with a memory card used for:
Backing up the application (program, symbols and constants)
Activating a standard Web server for the Transparent Ready class B10 integrated 
Ethernet port (depending on the model)
This memory card can be replaced by another type of memory card (to be ordered 
separately) that supports: 
Backing up the application and activation of the standard Web server (same as 
other card)
An 8 MB or 128 MB storage area, depending on the option card, for storing 
additional data organized in a file system (directories and sub-directories) 
Design and setup of Modicon M340 applications
To set up Modicon M340 automation platform processors, you need either: 
Unity Pro Small programming software
Unity Pro Medium, Large, Extra Large or XL Safety programming software 
identical to that used to set up Modicon Premium and Modicon Quantum automation 
platforms 
Depending on requirements, you may also need:
Unity EFB toolkit software for developing EF and EFB libraries in C language
Unity SFC View software for viewing and diagnostics of applications written in 
Sequential Function Chart (SFC) or Grafcet language
The function block software libraries provide Modicon M340 processors with the 
processing capability required to meet the needs of specialist applications in the 
following areas:
Process control via programmable control loops (EF and EFB libraries)
Motion control with multiple independent axis functions (MFB (Motion Function 
Block) library)
. The axes are controlled by Altivar 312/71 variable speed drives or 
Lexium 05/32 servo drives connected on the CANopen machine and installation bus. 
Note: Compatibility of BMX P34 20102/20302 processors with the Unity Pro software 
version
. 
BMX P34 20102/20302 processors with integrated CANopen bus are compatible with 
Unity Pro version u
 4.1. Both these processors can be used to customize configuration of the 
device Boot Up procedure compatible with all CANopen third-party products.
(1) Maximum number of application-specific channels per station. Only the application-specific 
channels actually configured in the Unity application count.
