The CX2500-Mxxx fieldbus master modules are left-sided attachments

for the Embedded PC series CX20xx, CX52x0. CX53x0 and CX56x0.

The use of systems with fieldbus master modules enables the segment

-like construction of control structures in extensive plants and machines

using further fieldbus components (Bus Couplers, Bus Terminal Controllers,

Drive Technology, etc.).

The CX2500-M310 fieldbus master module assumes the function of a

PROFIBUS master. Each module occupies a PCI Express® lane, so that a

total of four modules can be connected in any desired combination to the

left side of a CX20xx group. Compared with the Beckhoff PCIe® Fieldbus

Cards, the technical data of the fieldbus master modules are almost identical,

but with single channels.

The parallel operation of several identical or different masters is possible, e.g.

two PROFIBUS masters or a PROFIBUS master and a CANopen master.

In the case of mixed operation of master and slave connections, CX systems

act as intelligent gateways between different fieldbuses: data are received,

processed and fed into other fieldbuses. Master or slave connections network

several CX systems with one another strictly deterministically via the fieldbus

level. CX fieldbus modules can be retrofitted/exchanged by adding them to

existing CX systems. The scanning and recognizing of the modules, the

parameterization, the configuration of the connected I/O components and

the online diagnostics of the process/fieldbus status take place in the TwinCAT

System Manager.

The CX2500-Bxxx fieldbus slave modules are left-sided attachments

for the Embedded PC series CX20xx, CX52x0. CX53x0 and CX56x0.

The use of systems with fieldbus slave modules enables the use of 

a CX system as a subordinate local controller for the construction of

complex or modular systems. External process data are received from

the master and processed, or data from its own process peripherals

are returned to the master controller directly or processed.

The CX2500-B510 fieldbus slave module assumes the function of a 

CANopen slave. Each of these modules occupies a PCI Express®

lane, so that a total of four of these modules can be connected in any

desired combination to the left side of a CX20xx group. The fieldbus

slave modules are single-channel modules.

The parallel operation of several identical or different slaves is possible,

e.g. two PROFIBUS slaves or a PROFIBUS slave and a CANopen slave.

a total of four of these modules can be connected in any desired

combination to the left side of a CX20xx group. The fieldbus slave

modules are single-channel modules. The CX2500-B310 fieldbus slave

module for PROFIBUS can present itself to the master as a multiple

(max. quadruple) virtual slave station, resulting in a four-fold increase

in the quantity of exchanged process data.

e.g. two PROFIBUS slaves or a PROFIBUS slave and a CANopen slave.

PLC, motion control, interpolation, and visualization

Multi-core CPUs in conjunction with TwinCAT 3 enable PLC projects to be distributed to several

cores, resulting in significant performance gains. Likewise, all TwinCAT Motion Control functions

can be used to the full: in addition to simple point-to-point movements, more complex multi-axis

functions such as electronic gearing, cam plate and flying saw are possible. Interpolating 3D path

movements and complex axis kinematics are also executable, however, the transition to more

powerful devices from the CX2000 series must be checked in the individual case here.

In addition to handling real-time control tasks the TwinCAT 3 real-time kernel leaves enough time

for the user interface (HMI). Due to the good performance of the graphic unit integrated in the CPU,

even demanding visualizations can be realized with modern user interfaces.

The CX5200 series is also available as an Embedded PC without operating system and without

TwinCAT. The extended operating temperature range from -25 to +60°C enables use under climatically

challenging conditions.

EtherCAT as a fast I/O system

The Embedded PCs were developed with a view to optimized interaction with EtherCAT.

Therefore, each CX5200 controller has an internal EtherCAT master port. This can be fed

to the right to the I/O level in order to enable the use of EtherCAT I/O Terminals.

If necessary, however, it can also switch automatically to the K-bus terminal system.

Both Ethernet ports of the CX5200 can be used both for standard IT connections and as

additional EtherCAT master interfaces. In conjunction with EtherCAT and TwinCAT, it is

possible to implement very fast control processes in the microsecond range (eXtreme Fast

Control Technology).

Due to the separate Gigabit-Ethernet interfaces it is also possible to use EtherCAT with cable

redundancy by using one of the Ethernet interfaces as a redundancy port. In addition, the

devices can be operated with a EtherCAT slave interface in the multi-option interface so that

several intelligent controllers can be synchronized via an EtherCAT network.

Compact, fanless multi-core controller with Intel Atom® E3900

The DIN-rail mountable, fanless Embedded PCs from the CX5200 series are

equipped with Intel® processors from the Atom®-X series. As with all newer

Embedded PCs, the entire range of K-bus or EtherCAT Terminals can be directly

connected on the right-hand side.

The boot and storage medium is an interchangeable, industrially compatible CFast card,

whose slot is accessible behind a cover. The CFast card serves as a substitute for a hard disk;

i.e. the operating system as well as TwinCAT and user projects are stored on it.

Fast hardware exchange is thus possible if service is required; a software update can be

performed simply by replacing the card on site. The built-in capacitive 1-second UPS

ensures secure backup of persistent application data on the CFast card. The data and

time are buffered by an exchangeable battery (button cell).

The main features of the CX5200 device series are:

• CPUs from the Intel Atom®-X series (“Apollo Lake”) with two or four cores

• fanless cooling

• comfortable 4 or 8 GB RAM

• electrically isolated 24 V DC power supply unit, UPS OCT-capable

• built-in capacitive 1-second UPS for persistent data storage

• left-sided extension interface for a system module

The CX5200 series supplements the existing CX5100 devices with absolutely identical

housing dimensions. What is new, however, is the expandability on the left-hand side

by a module of the type CX2500-xxxx, with an additional space requirement of about

22 mm in width. This allows further PC interfaces (e.g. two additional 1 GB Ethernet

ports) or fieldbus interfaces (e.g. for PROFIBUS, CAN, etc.) to be added to the system.

The basic equipment of the CX5200 Embedded PCs includes two independent

Gbit-Ethernet interfaces, four USB 3.0 ports, one DVI-D interface and a multi-option

interface that can be flexibly equipped ex factory, for example with a serial port, a fieldbus

connection or a second video connection with DVI-D, HDMI or DisplayPort.

The CX5140 has an Intel Atom® quad-core processor with a clock

rate of 1.91 GHz. This makes genuine multi-core technology possible

in the Embedded PC segment. The hardware interfaces in this series

are oriented and implemented identically to those of the existing

CX5000 series. Two independent, Gigabit-capable Ethernet interfaces

as well as four USB 2.0 and a DVI-I interface are available.

A multitude of further connection options and gateway functions is

created by an optional interface, which can be pre equipped ex factory,

as well as the I/O level, which can optionally consist of either E-bus or

K-bus terminals.

The CX5140 is characterized by low power consumption and fanless design.

Depending on the installed TwinCAT runtime environment, the CX5140

can be used for implementing PLC or PLC/motion control projects with

or without visualization. The execution of motion control applications

with interpolating axis movements is also possible.

Like the CX5000. the CX5100 series has a compact design; a modular

device with extension modules like in the CX2000 series is not available.

The main features of the CX9240 device series include:

• high-performance 1.2 GHz Arm® Cortex®-A53 CPUs with four cores

• 2 GB LPDDR4 RAM

• two independent 1 Gbit Ethernet interfaces

• DisplayPort instead of DVI

• Beckhoff RT Linux®

• built-in capacitive 1-second UPS

• electrically isolated 24 V DC power supply

Further standard features of the CX9240 include four USB 3.0 interfaces, a DisplayPort,

and a multi-option interface that can be flexibly assigned ex factory – for example,

 with a serial port or a fieldbus connection.

The boot and storage medium is an interchangeable, industry-standard microSD card,

which can be accessed via a slot on the front of the housing. This is used to store not

only the operating system, but also TwinCAT and user projects. Beckhoff RT Linux® is

used as operating system.

The TwinCAT automation software transforms the CX9240 system into a high-performance

PLC and motion control system that can be operated with or without visualization.

Optionally, the unit can be ordered with a fieldbus or serial interface.

The connection for the Beckhoff I/O systems is directly integrated into the CPU module.

The device offers automatic bus system identification (E-bus or K-bus) and switches to

the corresponding mode. The extended operating temperature range between-25°C and

+60°C allows it to be used even in climatically demanding situations.

The CX9240 Embedded PC is a compact, DIN rail-mountable Ethernet control system

with a 1.2 GHz Arm® Cortex®-A53 CPU. It represents a further development of the

existing CX9020 and relies on a faster CPU with four cores and a modern 64 bit 

architecture. The multi-core CPU allows PLC projects to be distributed to several cores

for significantly enhanced performance.

The CX9240 features two independent 1 Gbit Ethernet interfaces, which enable

significantly higher transfer rates compared to its predecessor. The main memory

comprises 2 GB LPDDR4 RAM, which doubles the capacity of the compact controller

and, together with the more modern CPU and the same low power consumption,

opens up new application areas and possibilities for the CX9240.
