WOODWARD SST-DN3-PCU-2-E DeviceNet Master/Slave PCI Communication Card – SST-DN3-PCI-2 Series
When a DeviceNet node loses its communication interface, the consequences on the plant floor are immediate and costly: drives go into fault, conveyors stop mid-cycle, and the entire production line halts while technicians scramble to diagnose a missing or failed PCI card. In process-critical environments — bottling lines, automotive assembly, or chemical dosing systems — even a 15-minute unplanned downtime can translate to thousands of dollars in lost output. The SST-DN3-PCU-2-E is the component that keeps that scenario from happening.
Within the WOODWARD SST DeviceNet PCI card family, the SST-DN3-PCU-2-E occupies the dual-port master/slave position — the configuration chosen when a single host PC must simultaneously manage two independent DeviceNet networks or when one network requires master control while the other operates as a slave node. This architecture is particularly relevant in distributed motion control and safety-rated I/O applications where network segregation is a design requirement. The SST DeviceNet PCI series has been deployed across tens of thousands of installations globally, making it one of the most field-proven DeviceNet host interface solutions available for PCI-bus host systems.

Key Features & Benefits
- Dual independent DeviceNet channels — Eliminates the need for two separate PCI cards when managing segregated networks, reducing slot consumption and simplifying cable routing in panel-mount PCs.
- Master/Slave configurable per channel — Each port can be independently assigned as master or slave at the driver level, supporting mixed-topology architectures without hardware changes.
- Supports up to 64 I/O connections per master channel — Sufficient for large distributed I/O trees in automotive body shop or food processing lines without requiring a secondary scanner.
- ODVA-conformance tested — Guarantees interoperability with any DeviceNet-certified device from any vendor, eliminating integration risk when mixing drives, sensors, and valve manifolds on the same network.
- Windows and Linux driver support with SST API — Reduces software integration time; the SST API is consistent across the entire SST card family, so engineers already familiar with SST-DN3-PCI-1 can migrate without rewriting application code.
- Field-replaceable without network reconfiguration — Node address and baud rate are stored in the host software, not on the card, so a card swap does not require re-commissioning the DeviceNet network.
Industry & Equipment Applications
- Automotive Assembly — Body welding lines and paint shop conveyors using DeviceNet-connected servo drives and pneumatic valve islands; the dual-channel capability allows body and chassis networks to be managed from a single panel PC.
- Food & Beverage Processing — Bottling and filling machines where DeviceNet I/O modules control fill valves, cap torque sensors, and reject gates; the card’s 0–60°C operating range suits wash-down adjacent control cabinets.
- Oil & Gas Upstream — Wellhead control panels and skid-mounted compressor packages using DeviceNet for local I/O; the card interfaces the host SCADA workstation directly to field instruments without an intermediate gateway.
- Pulp & Paper — Winder and rewinder drives networked via DeviceNet for tension control; master mode with 64 connections supports large drive arrays on a single network segment.
- Material Handling & Logistics — Sortation systems and automated storage/retrieval (AS/RS) where barcode readers, photo-eyes, and motor starters share a DeviceNet trunk; dual-channel separates inbound and outbound conveyor networks.
- Water & Wastewater Treatment — Pump station control panels where DeviceNet connects VFDs, level sensors, and flow meters to a host PC running SCADA; the card’s industrial temperature rating suits outdoor kiosk enclosures.
System Integration & Compatible Parts
Upstream host requirements: Any PCI-bus industrial PC or workstation running Windows XP/7/10/11 (32/64-bit) or Linux with SST driver package installed. Typically paired with WOODWARD or third-party SCADA/HMI software via OPC-DA/UA server.
Downstream DeviceNet devices (examples): Allen-Bradley 1756-DNB (ControlLogix DeviceNet bridge), Turck BL20 DeviceNet I/O modules, SMC EX260 valve manifolds, Cognex In-Sight cameras with DeviceNet I/O.
Related SST cards in the same family:
- SST-DN3-PCI-1 — Single-channel version; substitute when only one DeviceNet network is required and PCI slot space is constrained.
- SST-DN3-104-2 — PC/104 form factor equivalent for embedded systems; same dual-channel functionality, different bus.
- SST-DN3-PCI-2 — The base card without the PCU (protocol co-processor upgrade); the SST-DN3-PCU-2-E includes the enhanced co-processor for higher scan rates. Verify firmware version before substituting.
Substitution note: Before replacing SST-DN3-PCU-2-E with SST-DN3-PCI-2, confirm that the host application does not rely on the enhanced co-processor scan rate (<1 ms cycle time). Functional substitution is valid for applications with ≥2 ms scan requirements.
Our Quality Assurance Process
Every WOODWARD SST-DN3-PCU-2-E unit shipped from Konmask.com passes through a four-step verification process:
- Visual & Physical Inspection — PCB surface, connector pins, and card bracket examined for transport damage, oxidation, or counterfeit indicators (silkscreen, component markings cross-referenced against OEM documentation).
- Functional Power-On Test — Card installed in a test PCI chassis; SST diagnostic utility confirms both DeviceNet channels initialize, LED status indicators respond correctly, and firmware version is verified.
- DeviceNet Communication Verification — Each channel looped to a known-good DeviceNet slave device; master scan list loaded and I/O data exchange confirmed at all three baud rates (125/250/500 kbps).
- Documentation & Packaging — Unit serialized, test record filed, and card packed in anti-static bag with foam insert. ESD-safe outer carton used for all shipments.
Available documentation upon request: Test report, product datasheet, CE declaration of conformity, ODVA conformance certificate reference, packing list.

Frequently Asked Questions
Q: Is the WOODWARD SST-DN3-PCU-2-E compatible with Windows 10 and Windows 11 64-bit systems?
A: Yes. SST provides signed 64-bit drivers for Windows 10 and Windows 11. The driver package is available from the SST/Woodward support portal. Confirm the driver version matches your firmware revision before installation.
Q: What is the difference between SST-DN3-PCU-2-E and SST-DN3-PCI-2 — can they be used interchangeably?
A: The SST-DN3-PCU-2-E includes an enhanced protocol co-processor (PCU) that enables faster scan cycle times (sub-millisecond) compared to the base SST-DN3-PCI-2. For applications requiring scan rates of 2 ms or slower, the two cards are functionally interchangeable at the software level using the same SST API. For high-speed motion or safety applications requiring <1 ms cycles, the PCU variant is required.
Q: Can I use the SST-DN3-PCU-2-E as a DeviceNet slave on one channel and a master on the other simultaneously?
A: Yes. Each channel is independently configurable. A common deployment is Channel 1 as master (scanning field I/O) and Channel 2 as slave (responding to a PLC scanner on a supervisory network). This mixed-mode configuration is supported natively by the SST API and does not require separate driver instances.
