System overview
The system
With the CX series of Embedded PCs Beckhoff has combined PC technology and modular I/O level to form a top-hat
rail unit in the control cabinet. The CX1020 extends the CX product family by a version with higher CPU performance.
The CX1020 enables direct connection of Bus Terminals and EtherCAT terminals.
While the CX1000 features an 266 MHz AMD Geode processor, the CX1010 is equipped with a 500 MHz AMD®
Geode LX 800Intel(r) CPU. It is an energy-saving device that operates with ultra-low core voltage and features low
thermal power dissipation of only 8 W TDP (thermal design power). As a result, no fan is required despite the
compact design of the CX1010 Embedded PC. Since Compact Flash is used as boot and memory medium, no
rotating media are required in the controller. This is an important aspect for increasing the MTBF (Mean Time
Between Failures) of the overall system.
The case and assembly concept of the CX1010 is similar to that of its smaller brother, the CX1000:
It also consists of several components that can be assembled by the user. The simplest configuration consists of a
CPU module and a multi-functional power supply unit. The PC104 bus is used for the connection between these and
all other CX components, although in the CX1020 this was extended with EtherCAT signals. The basic CPU module
is equipped with one RJ-45 socket.
Like the CX1000, the CX1020 can be expanded with optional system interfaces. A DVI-I (=DVI-D + VGA) output, two
USB-2.0 interfaces, up to four RS232 interfaces and audio are available. The four RS232 interfaces feature opto-
decoupling and can optionally be implemented as RS422/RS.
The same reusability also applies to the multi-functional power supplied units (CX1100-000x) of the CX1020: one
without I/O terminal connection, one with K-Bus connection, one with K-Bus and IP-Link connection for IP-67-
protected Fieldbus Box modules, and a power supply unit with direct connection facility for Beckhoff EtherCAT
Terminals.
EtherCAT as a fast I/O system
The CX1010 Embedded PC was developed for optimum interaction with EtherCAT. The Ethernet interface of the
CPU module is not primarily intended for EtherCAT operation. The EtherCAT connection is established via the
EK1110 (EtherCAT) extension terminal. The power supply CX1100-0004 establishes the possibility to connect E-Bus
Terminal to the CPU Module.
