B&R specifies the X20CP1486 as a high-performance X20 CPU with an additional I/O processor. Its onboard interfaces include Ethernet, POWERLINK, USB, RS232, and X2X Link, while the single modular interface slot distinguishes it from the wider X20CP3486.
Product Introduction
The B&R X20CP1486 is a central CPU module for the B&R X20 automation system. It combines an Intel Celeron 650 processor with an integrated I/O processor, 64 MB SDRAM, 1 MB SRAM, removable CompactFlash application storage, and onboard real-time communication through POWERLINK. The controller is intended for demanding machine-control and process-control applications within the X20 platform.
The onboard Ethernet and POWERLINK interfaces allow the CPU to coordinate standard network communication and deterministic machine-level communication without requiring a separate communication card. X2X Link provides the connection to distributed X20 I/O, while one modular interface slot allows additional interface functionality when required.

Application Scenarios & Field Pitfalls — Engineer’s Perspective
Engineering Pain Point
When an X20CP1486 fails, replacing the CPU is only part of the recovery process. The CompactFlash application, Automation Studio project, firmware/hardware configuration, retained variables, network parameters, and POWERLINK configuration all need to be considered.
A CPU that powers up correctly can still fail to reproduce the original machine behavior if the application memory or Automation Studio hardware configuration does not match the installed system.
Typical Applications
- B&R X20 PLC and machine-control systems
- High-speed machine automation using POWERLINK
- Process-control applications using X20 distributed I/O
- Motion systems using B&R ACOPOS drives
- Industrial systems using X2X Link distributed I/O
B&R specifically states that the X20CP1486 supports ACOPOS and Visual Components, and positions the CPU for applications ranging from high-end machine manufacturing to demanding process control.
Technical Pitfalls to Avoid
- Do not confuse the with a generic X20 I/O module.
It is the system CPU and contains the PLC processing function. X20 I/O modules depend on the CPU and X2X Link architecture for application-level control. - Check the CompactFlash application memory.
B&R explicitly states that the application memory must be ordered separately. The CPU itself is supplied with a backup battery and other standard accessories, but the CompactFlash card is a separate item. - Do not assume X20CP3486 is a direct physical equivalent.
B&R identifies the X20CP3486 as the wider related CPU, while the has only one modular interface slot and a smaller housing. A migration therefore requires checking the existing interface-module arrangement and cabinet space. - Watch the cooling conditions.
B&R specifies 0–55°C operation with the fan operating, while fanless operation is limited to 0–45°C under the stated conditions. The fan is monitored and can be replaced externally. - Verify the installed Automation Studio hardware version.
B&R provides hardware upgrades for the across Automation Studio V2.6, V3.0, and V4.0 environments. The engineering workstation and installed CPU hardware should therefore be checked before commissioning a replacement.

Recommended procurement description:
B&R X20 CPU Module, Intel Celeron 650, 64 MB SDRAM, 1 MB SRAM, Ethernet, POWERLINK V1/V2, 2 × USB, RS232, X2X Link Master, 1 Modular Interface Slot, 24 VDC.
The key point for replacement work is that is the central processing unit of the X20 system, not an ordinary X20 I/O module. Its CompactFlash application, POWERLINK configuration, X2X Link topology, firmware, and interface-module arrangement should all be checked before commissioning. B&R’s current product documentation continues to provide technical data and hardware-upgrade documentation for this model.
