The basic equipment of the CX1020 Embedded PC from Beckhoff features an Intel® Celeron® M 1 GHz processor with 512 kbyte L2 cache. However, many applications do not require the full power of this CPU. For this reason Beckhoff offers a less expensive version with the option “zero second level cache”.

In this variant, a processor without a second level cache (L2 = 0 kbyte) is used instead of the 1 GHz processor with 512 kbyte second level cache (L2). The advantage of this option is that costs can be saved while retaining compatibility: none of the basic characteristics of the CX1020 are changed, apart from the slightly lower CPU power.

The controller does not require a fan or other rotating parts. The main memory is selectable: 256 MB DDR RAM as standard, expandable to 512 MB or 1 GB. The basic configuration of the CX1020 includes a 64 MB Compact Flash card and two Ethernet RJ 45 interfaces. The CX power supply units offer a direct interface between the CX1020 and the Beckhoff Bus Terminals or EtherCAT Terminals.

The operating system can be Windows CE or Windows XP Embedded.
