Product overview
2.2 System Overview
CX2020, CX2030, CX2040 | Basic CPU module
The system
The CX2020 has a 1.4 GHz Intel® Celeron® CPU, the CX2030 has a 1.5 GHz Intel® Core™ i7 dual­core
CPU, the CX2040 has a 2.1 GHz Intel® Core™ i7 quad­core CPU. In the CX2020 and CX2030 the controller
is fanless and has no rotating components. Due to its high power, the CX2040 has a fan with ball bearings
and speed monitoring. In addition to the CPU and chipset the basic modules also contain the main memory.
For the CX2020 and CX2030 the size is 2 GB. Up to 4 GB are possible as an option. The CX2040 has 4 GB
of RAM as standard. The controller boots from the CFast flash memory card. The basic configuration of the
modules includes a CFast memory card, two independent Gbit Ethernet interfaces, four USB 2.0 interfaces
and a DVI­I interface. The CPU has an internal 128 KB NOVRAM, which functions as a persistent data
memory if no UPS is used. Optionally the devices can be ordered with a serial or fieldbus interface. Other
components from the CX2000 family can be connected via the multi­pin terminals on either side. The
operating system is Microsoft Windows Embedded Standard 7 P. Up to four modules can be connected to
the basic CPU module. The connection order is irrelevant. Internally the modules are connected via PCI
Express and can be plugged to the CPU "in the field". The power supply for the CPU module comes from a
CX2100 power supply module, which is connected on the right­hand side of the CPU. Two further CFast
memory card modules (CX2550 0010) can be connected between the power supply unit and the CPU, so
that a total of up to three CFast cards can be used. RAID can be used in situations where more than one
CFast card is used.
The CX2020, CX2030 and CX2040 Embedded PCs extend the CX product family with versions with very
high CPU power (optionally with multi­core) and enable direct connection of Bus Terminals or EtherCAT
Terminals. The CX2000 in conjunction with EtherCAT and TwinCAT enables very fast control processes in
the microsecond range (eXtreme Fast Control Technology). The basic CPU modules have two independent
Gbit Ethernet interfaces, four USB 2.0 interfaces and a DVI­I interface as standard. A serial or a fieldbus
