Description
CX9020 | Basic CPU module
The CX9020 is a compact, DIN rail-mountable Ethernet control system with 1 GHz ARM Cortex™-A8 CPU. The connection for the Beckhoff I/O systems is directly integrated into the CPU module. The unit offers automatic bus system identification (E-bus or K-bus) and independently switches in the corresponding mode. The CX9020 comprises the CPU with two microSD card slots, the internal RAM and 128 kB NOVRAM as non-volatile memory. The basic configuration also includes two switched Ethernet RJ45 interfaces, four USB 2.0 interfaces and a DVI-D interface. The RJ45 interfaces are connected to an internal switch and offer a simple option for creating a line topology without the need for additional Ethernet switches. The operating system is Windows Embedded Compact 7. TwinCAT automation software transforms a CX9020 system into a powerful PLC and motion control system that can be operated with or without visualization. Optionally, the unit can be ordered with a fieldbus, serial or audio interface.
The extended operating temperature range between -25 °C and +60 °C enables application in climatically demanding situations.
