B&R automation systems are widely used in machine automation, packaging, plastics, robotics, material handling, printing, food processing and advanced manufacturing environments. Many B&R controllers, industrial PCs, I/O systems, HMIs, servo drives and communication components continue operating reliably long after specific product families have reached mature, discontinued or legacy status.
For maintenance engineers, OEM machine builders and procurement teams, maintaining an existing B&R automation system is often more practical than replacing an entire machine control architecture. Sourcing compatible legacy B&R automation parts can help extend equipment life, reduce downtime and preserve proven machine performance.
This guide explores major legacy B&R automation product families including Automation PC, X20 I/O, X67 I/O, Power Panel, ACOPOS servo drives, PLC controllers, communication modules and supporting industrial components.

About Legacy B&R Automation
B&R automation equipment is commonly used in high-performance machine control environments where precision, modularity and compact system design are important. These systems are frequently found in packaging machinery, plastics processing, robotics, textile machinery, printing equipment, assembly systems and OEM-built machines.
Many legacy B&R systems remain in operation because they are deeply integrated into the original machine design. Replacing a complete control architecture can involve software changes, hardware redesign, drive reconfiguration, HMI redevelopment and machine recommissioning.
Legacy B&R automation parts may include industrial PCs, PLC controllers, X20 and X67 I/O modules, Power Panel HMIs, ACOPOS servo drives, communication modules, power supplies, bus modules, terminal blocks and related accessories.
Understanding B&R Product Lifecycle
B&R automation products move through lifecycle stages as newer controllers, I/O technologies, drive systems and industrial PC platforms are introduced. Understanding these stages helps maintenance teams plan spare parts before critical components become difficult to source.
| Lifecycle Stage | Description | Typical Maintenance Action |
|---|---|---|
| Active | Current production equipment. | Standard procurement may still be possible. |
| Mature | Still installed but approaching replacement. | Begin spare parts and lifecycle planning. |
| End of Sale | Standard supply has ended or is limited. | Evaluate legacy sourcing options. |
| Obsolete | No longer manufactured as a current item. | Source through obsolete and legacy automation networks. |
| Legacy | Still operating inside existing machines and production systems. | Maintain through planned spare parts management. |
Why B&R Parts Become Legacy
B&R parts become legacy as machine control technology evolves, industrial PC platforms change, communication standards advance and newer controller or I/O generations are introduced.
Machine Control Evolution
Newer PLC, motion and automation platforms gradually replace earlier B&R control architectures.
Industrial PC Hardware Changes
Processor, storage, display and operating system changes can make older industrial PCs difficult to replace directly.
Component Availability
Older electronic assemblies, drive modules, displays and communication cards may become harder to manufacture or source.
Long Machine Lifecycles
OEM machines often remain productive for many years after individual automation components become obsolete.
Legacy status does not mean a B&R system is no longer useful. Many systems continue supporting production reliably when maintained with compatible spare parts and accurate configuration records.
Legacy B&R Control Systems
B&R control systems are commonly used in machine automation environments where compact hardware, integrated motion and fast control performance are required.
| Product Family | Typical Applications | Legacy Relevance |
|---|---|---|
| Automation PC | PC-based machine control and industrial computing | Critical in long-life OEM machines |
| PLC Controllers | Machine automation and process control | Often deeply integrated into control architecture |
| Power Panel | Combined HMI and controller applications | Common in legacy machine interfaces |
| Compact Controllers | Standalone machine control | Frequently installed in OEM equipment |
Automation PC
B&R Automation PCs are used in PC-based machine control, industrial computing and advanced automation applications. Legacy Automation PC replacement can be complex because hardware, operating system, installed software, storage configuration and communication interfaces may all affect compatibility.
PLC Controllers
B&R PLC controllers coordinate machine logic, I/O, motion and communication. When sourcing legacy controllers, exact model number, firmware, software environment and installed program requirements should be reviewed carefully.
Power Panel Systems
Power Panel devices combine operator interface functionality with control capabilities in many machine applications. Legacy Power Panels may be required where screen applications, controller functions, panel dimensions and communication settings must be preserved.
B&R I/O Systems
B&R I/O systems connect field devices, sensors, actuators and machine signals to the controller. Many legacy machine control systems rely on specific I/O layouts and communication structures.
X20 I/O Modules
X20 I/O systems are widely used in modular machine automation. They support digital signals, analog signals, communication interfaces, temperature measurement and specialised machine functions.
When sourcing legacy X20 components, module type, terminal base, signal function, power requirements and installed configuration should be verified.
X67 I/O Modules
X67 I/O systems are commonly used for machine-mounted and distributed I/O applications. These modules may be installed close to sensors, actuators and production equipment in demanding industrial environments.
Bus & Communication Interfaces
Communication modules and bus interfaces connect B&R systems to industrial networks, field devices and machine-level components. Compatibility with the installed architecture is essential.
B&R HMI & Power Panel Systems
B&R HMI and Power Panel systems provide operator control, machine visibility, diagnostics and configuration access. Because these units are used daily, they are often among the most important legacy components in machine operation.
When sourcing legacy B&R HMI components, maintenance teams should confirm screen size, mounting format, communication interface, installed software, controller function and power requirements.
ACOPOS Drives & Motion Control
B&R ACOPOS servo drives are used in motion control applications requiring precision, synchronisation and high-performance machine movement. These systems are common in packaging, printing, plastics, robotics and automated production lines.
ACOPOS Servo Drives
Legacy ACOPOS servo drives may remain essential where existing machine axes, motors, feedback systems and software configurations are designed around specific drive models.
Compatibility between servo drive, motor, controller, encoder feedback and machine software should always be reviewed before sourcing a replacement.
Motion Control Components
Motion systems may include drive modules, power modules, motors, cables, communication interfaces and safety-related components. A single replacement part should be evaluated within the complete motion architecture.
