CX2042 | Basic CPU module

The CX2042 has an Intel® Xeon® CPU with a clock rate of 2.2 GHz (4 cores). A fan with ball bearings and speed monitoring is integrated into the basic CPU module. In addition to the CPU, the basic module also contains the main memory with a size of 8 GB RAM, optionally available with up to 32 GB. The controller boots from a CFast flash memory card where both the operating system as well as user programs and data are stored.

The CPU has an internal 128 kB NOVRAM, which acts as a persistent data memory if no UPS is used.

Microsoft Windows 10 IoT Enterprise LTSB 64 bit is used as operating system. The use of TwinCAT 3 allows automation tasks to be distributed across the various cores of the Intel® Xeon® CPU.

All system modules from the CX2000 series for left- or right-sided functional extensions can be connected. 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 CX2100-0014 power supply module. Up to two mass storage modules (either CX2550-0010 CFast modules or CX2550-0020 2½-inch SSD modules) can be plugged in between the power supply unit and the CPU, allowing the use of up to three mass storage devices in total.
