Product Description:
The CX8130-0155 is an embedded PC manufactured by Beckhoff for the CX Embedded PC Systems series. Designed as a PLC and communication gateway, it hosts control logic, handles local I/O, and exchanges process data with higher-level networks inside industrial automation equipment. Its DIN-rail housing makes it suitable for compact control cabinets. The unit can serve as the primary logic component on small and medium machines where limited space, low thermal output, and deterministic operation are required.
An Arm Cortex-A9 processor executes application code with a minimum task cycle of 500 µs, providing a deterministic response for motion or process loops. Program files and runtime data reside on a 512 MB microSD card that uses SLC technology to extend write endurance during frequent logging. The terminal interface supports both K-bus and E-bus connections, so the controller can operate traditional digital modules or EtherCAT terminals without adapters. Application development is performed in the TwinCAT 3 environment, which supports all IEC 61131-3 languages. During operation, the CX8130-0155 appears as a fieldbus slave device. Its Ethernet port provides programming access, HMI connectivity, and diagnostic communication without additional cards.
The enclosure measures 68 mm in width, 73 mm in depth, and 100 mm in height, allowing high-density mounting beside power supplies and I/O slices. An internal 1-second UPS secures retentive variables when the main power supply experiences a brief interruption, eliminating the need for an external battery pack during short outages. Because the design is headless, it does not include a monitor port. Initial setup is performed through the Ethernet interface or USB service port. The controller follows the IEC 61131-3 programming standard and operates exclusively in slave mode on the selected fieldbus. Its SLC flash storage provides the write endurance needed for control applications that regularly save runtime data, event records, or persistent variables.
