What Is a "B&R Computer"?
When engineers search for a "B&R computer," they are usually referring to the industrial PC and panel PC families from B&R Industrial Automation — a well-known Austrian automation vendor whose portfolio includes the Automation PC 3100, Panel PC 3100, Panel PC 2200 and Panel PC 2100 series. These systems are built around Intel® Core™ i3/i5/i7 processors and are designed for machine control, HMI, motion and factory-floor data acquisition, often in harsh environments with wide temperature ranges, shock, vibration and dust exposure.
B&R industrial PCs are typically deployed as part of a broader automation architecture — running PLC logic, visualization software, motion control or SCADA layers on the machine itself. The Automation PC 3100, for example, pairs a compact chassis with current-generation Core i-series performance, while the mobile variants add IP69K sealing and extended operating temperatures for vehicles and outdoor machinery. Panel PC models integrate the computer and touch display into a single front-of-machine unit.
What to Look For in an Industrial PC
If you are specifying a computer for a B&R-based or similar automation setup, the key selection criteria are broadly the same across vendors:
| Requirement | Typical Specification |
|---|---|
| Processor | Intel® Core™ i3 / i5, 12th–14th generation |
| Memory | 8–32 GB DDR4/DDR5 |
| Storage | 128 GB – 1 TB SSD |
| Serial ports | RS-232/RS-485 via DB9 for legacy PLCs and drives |
| Networking | Dual Gigabit Ethernet for control and IT segregation |
| Mounting | DIN rail, VESA or panel mount |
| Cooling | Fanless, wide-temperature operation |
| OS | Windows 11 Pro / IoT, Linux, or no OS for custom images |
Serial connectivity remains important in automation: many drives, weighbridges, barcode readers and older controllers still communicate over RS-232 or RS-485, which is why industrial computers with multiple DB9 ports are still in demand alongside modern USB and Ethernet interfaces.
Use Cases and Applications
Industrial computers in this class are used for machine HMI and SCADA nodes, vision and inspection stations, data concentrators on production lines, building automation gateways, and edge devices that pre-process plant data before sending it to a server or cloud. Fanless designs suit dusty or high-vibration environments — packaging lines, textile mills, metalworking shops and mobile equipment — where a fan would draw in contaminants and fail early.
For retrofit projects, an industrial PC with legacy serial ports and a standard x86 instruction set is often the simplest way to modernize an existing control cabinet without rewriting the application layer. Where the automation software runs on Linux, models shipping with Ubuntu or an embedded Linux image avoid the cost of a Windows licence.
Thinvent Industrial Computers for Automation and Machine Control
Thinvent manufactures industrial computers, mini PCs, thin clients and all-in-one PCs for deployment in factories, kiosks and control rooms worldwide. The Thinvent IPC3 series, for example, pairs an Intel® Core™ i3-1215U processor (6 cores, up to 4.4 GHz, 10 MB cache) with 16 GB DDR4 RAM and a 1 TB SSD, and is available with quad DB9 serial ports for connecting PLCs, drives and legacy instrumentation. Operating system options include Windows 11 Pro, Windows 11 IoT Value, DOS, and Thinux™ embedded Linux, so the same hardware can be standardized across mixed-software fleets. Fanless construction, wide input power and DIN-rail or VESA mounting make these systems suitable as alternatives to traditional automation-vendor PCs, particularly where a compact, serviceable x86 platform with rich serial and Ethernet I/O is required.
