Applications & Industry Context
ARCNET remains one of the most robust and deterministic industrial networking technologies for control systems that require guaranteed response times and simple, reliable communication. The TEWS ARCNET TPMC815-11 brings this trusted technology to CompactPCI platforms, providing a solid bridge between embedded computers and ARCNET-based field networks.
Used extensively in manufacturing automation, power distribution, and transportation control systems, this board enables fast and stable data transfer in environments where timing precision and communication stability are critical. In factory automation, the TEWS ARCNET TPMC815-11 serves as a communication backbone for PLCs and motion controllers that rely on deterministic updates between devices.
In railway signaling or power station control systems, engineers deploy the TPMC815-11 to connect embedded computers to distributed I/O and safety systems using ARCNET’s token-passing protocol — ensuring data packets are exchanged without collisions or random latency. Its CompactPCI format ensures easy integration into rack-mounted embedded controllers, while its rugged industrial design withstands mechanical stress, vibration, and extended temperature ranges.
The continued popularity of ARCNET in mission-critical sectors like nuclear power, marine systems, and industrial robotics speaks to its reliability. The TEWS ARCNET TPMC815-11 keeps that reliability alive in modern CompactPCI environments, extending legacy installations and supporting hybrid systems where ARCNET coexists with Ethernet, CAN, or Profibus.
Technical Features & Benefits
The TEWS ARCNET TPMC815-11 is engineered to provide dependable ARCNET connectivity in embedded and industrial systems built around the CompactPCI standard.
1. High-Performance ARCNET Communication:
The board supports ARCNET data rates of 156 kbps to 10 Mbps, offering flexibility for both legacy and high-speed applications. Its intelligent controller architecture offloads communication processing from the host CPU, ensuring smooth, deterministic network performance.
2. Versatile Interface Options:
Available with various physical interfaces — including coaxial (BNC), twisted-pair (RJ45), and fiber-optic transceivers — the TPMC815-11 adapts to a wide range of industrial network topologies. Engineers can match the interface to their specific field installation requirements.
3. CompactPCI Compatibility:
Fully compliant with the 3U CompactPCI form factor, this module fits standard racks and provides reliable backplane connectivity. It uses a PCI bridge for fast host access and DMA for high-speed data exchange, reducing CPU overhead.
4. Rugged Industrial Design:
The TPMC815-11 is designed for harsh environments with industrial-grade components, extended temperature range, and high mechanical resilience. This makes it suitable for embedded systems deployed in transportation, energy, and factory automation.
5. Easy Integration and Software Support:
Drivers and example software are available for major operating systems including Linux, VxWorks, and Windows. TEWS provides source-level support for rapid development and integration into existing ARCNET stacks or SCADA systems.
6. Proven Determinism and Reliability:
ARCNET’s token-passing protocol eliminates collisions and guarantees equal access to the network, a key advantage over Ethernet in time-critical applications. The TEWS ARCNET TPMC815-11 leverages this principle, delivering predictable and interference-free data exchange.
Together, these characteristics make it a reliable communication solution for any CompactPCI-based control system requiring real-time ARCNET networking.
Product Role & System Fit
The TEWS ARCNET TPMC815-11 functions as an ARCNET network interface controller for CompactPCI computers, acting as a communication bridge between the system’s CPU and field devices on the ARCNET network.
In automation architectures, it enables data exchange between PLCs, sensors, actuators, and supervisory systems using the ARCNET protocol. It provides deterministic communication timing — meaning every device in the network knows exactly when it can transmit — preventing data collisions and jitter that can disrupt control loops.
For engineers working on legacy system upgrades, this board allows smooth migration to CompactPCI platforms without rewriting the communication layer. Its drop-in compatibility with existing ARCNET cabling and devices simplifies integration, allowing control system modernization without disrupting proven field infrastructure.
When paired with TEWS’ other CompactPCI or PMC I/O modules, the TEWS ARCNET TPMC815-11 forms the backbone of reliable, modular automation systems that balance performance, flexibility, and long-term maintainability.

Installation & Maintenance Insights
Installing the TEWS ARCNET TPMC815-11 is straightforward for any engineer familiar with CompactPCI systems. Before inserting the module, ensure the system power is off and the slot is free from dust or debris. Slide the module gently into the 3U slot until it clicks into place with the CompactPCI connector fully seated.
Once installed, the device will be automatically detected by the host system BIOS and operating system, provided compatible drivers are present. TEWS supplies drivers with example configurations to get ARCNET networks running quickly. Engineers can select interface types, assign node IDs, and adjust timing parameters through software tools.
Routine maintenance is minimal — check connectors periodically for secure seating, and ensure coaxial or twisted-pair cables are free from damage. For fiber-optic variants, keep transceiver ports clean using lint-free swabs. The board’s solid-state design means no moving parts, minimizing failure risk and maximizing MTBF.
Many field users report years of continuous service from their TEWS ARCNET TPMC815-11 units, often in mission-critical systems that operate 24/7 without interruption.
