Product Description:
The X20CP0484 CPU module is manufactured by B&R Automation and belongs to the X20 Fieldbus Input Output Modules series. As the processing head of a distributed automation node, it handles application code execution, network communication, and I/O coordination within machine control architectures. By integrating Ethernet, POWERLINK, and USB interfaces, the module supports deterministic data exchange between field devices and higher-level systems while fitting the mechanical footprint and backplane of other X20 units. It is intended for mounting inside control cabinets where real-time performance and compact dimensions are important.
At its core, the module uses an ARM Cortex-A9 processor running at 667 MHz. Two 32 kB L1 caches, one for instructions and one for data, shorten fetch latency, while a 512 kB L2 cache supports larger code segments without continuous external memory access. Working memory consists of 256 MB DDR3 SDRAM, which is sufficient for multitasking real-time programs. Application code and the operating system are stored on a 2 GB eMMC flash device that combines moderate capacity with solid-state durability. Ethernet communication operates at 10/100 Mbit/s, making the controller suitable for standard factory networks, while a separate POWERLINK channel maintains 100 Mbit/s for deterministic motion tasks. Two USB host ports are available, and each can supply up to 0.2 A for service tools or removable drives.
The module safeguards user data through several nonvolatile resources. A remanent FRAM block provides 64 kB of persistent memory for variable storage between power cycles, and it is specified for 20,000 cycles of endurance before wear limits are reached. For bulk logging, the eMMC supports a cumulative write volume of 40 TB, while a guaranteed data retention period of 10 years supports long-term installations. Protection class IP20 indicates that the housing is finger-safe and relies on a cabinet for dust or moisture shielding. This arrangement matches the board’s intended use in indoor control panels.
