SST-DN3-PCI-2 DN3-PCI-1-E Product Description

The SST DN3-PCI-2 (also referenced as DN3-PCI-1-E) is a high-performance DeviceNet PCI interface card engineered by SST (Woodward) for seamless integration into industrial control architectures. Designed to serve as the communication backbone between host PCs or embedded controllers and DeviceNet fieldbus networks, this card delivers deterministic, low-latency data exchange across distributed I/O, drives, sensors, and actuators. Its role within a layered automation platform is not merely that of a communication adapter — it is a system-level enabler that bridges the control layer with the field device layer, ensuring signal integrity, network stability, and long-term maintainability across demanding industrial environments.

The SST DN3-PCI-2 is most effective when deployed as part of a cohesive, multi-layer automation architecture. In a typical DeviceNet-based control system, the DN3-PCI-2 resides in the communication layer, acting as the master interface between the supervisory control platform and the field device network. This card is commonly paired with Allen-Bradley / Rockwell Automation PLCs such as the ControlLogix L7x or CompactLogix L3x series, where it supplements or replaces onboard DeviceNet scanner modules, extending network reach and adding redundant communication paths.

At the I/O layer, the DN3-PCI-2 interfaces with distributed I/O blocks such as the Allen-Bradley 1734 POINT I/O or 1756 ControlLogix I/O modules, enabling real-time digital and analog signal acquisition across the DeviceNet trunk. For drive integration, the card communicates directly with PowerFlex 40 and PowerFlex 70 variable frequency drives, allowing speed reference, torque command, and fault status to be exchanged over the fieldbus without additional hardwired signal conditioning.

In the power layer, the system relies on 24 VDC DeviceNet network power supplies — typically rated at 4 A to 8 A — to maintain stable bus voltage across the trunk line. Proper power tap placement and termination resistors (121 Ω, 1%) at both ends of the trunk are essential for signal integrity at 500 kbps baud rates. The DN3-PCI-2 supports all three standard baud rates, making it compatible with legacy installations running at 125 kbps as well as modern high-speed networks.

For HMI integration, the DN3-PCI-2 works alongside SCADA platforms such as Wonderware InTouch, Ignition by Inductive Automation, or FactoryTalk View SE, where the SST SDK provides OPC DA/UA data bridging. This allows operators to monitor DeviceNet node health, I/O status, and network diagnostics directly from the HMI without requiring a separate gateway device. In architectures where a dedicated communication gateway is preferred, the SST DN3-PCI-2 can coexist with ProSoft Technology MVI56-DFNT or similar gateway modules, providing a redundant communication path for critical process data.

At the protection and diagnostic layer, the DN3-PCI-2 supports node-level fault detection, bus-off recovery, and duplicate MAC ID detection — features that are critical for maintaining network uptime in continuous process environments. When integrated with a SCADA historian or DCS front-end, these diagnostic signals can be logged and trended to support predictive maintenance programs. Terminal block assemblies and DIN-rail mounted signal isolators further protect the PCI card from ground loops and transient voltages common in heavy industrial environments such as steel mills, chemical plants, and water treatment facilities.

Manufacturing & Assembly Lines: In automotive and electronics assembly, the DN3-PCI-2 serves as the DeviceNet master for robotic end-effectors, conveyor drives, and vision system triggers. Its deterministic scan cycle ensures that all field devices are polled within a defined time window, supporting synchronized multi-axis motion sequences and reducing cycle time variability.

Power & Energy Facilities: In substation automation and power distribution panels, the DN3-PCI-2 enables communication between SCADA workstations and intelligent electronic devices (IEDs) over DeviceNet, complementing IEC 61850-based architectures where legacy fieldbus nodes must be retained. The card's robust CAN physical layer tolerates the electromagnetic interference levels typical of high-voltage switchgear environments.

Petrochemical & Process Control: In refinery and chemical plant DCS architectures, the DN3-PCI-2 integrates with safety instrumented systems (SIS) by providing a non-safety communication path for diagnostic data from DeviceNet-connected field instruments, pressure transmitters, and solenoid valve banks. This separation of safety and non-safety communication paths is consistent with IEC 61511 functional safety guidelines.

Water & Wastewater Treatment: Municipal water treatment SCADA systems use the DN3-PCI-2 to communicate with pump station drives, level sensors, and chlorination dosing systems distributed across geographically separated lift stations. The card's multi-master capability allows redundant SCADA servers to share network access without bus contention.

Mining & Metallurgy: In ore processing and smelting operations, the DN3-PCI-2 connects conveyor belt drives, crusher motor starters, and dust suppression valve actuators to the plant DCS. Its wide operating temperature range and industrial-grade PCI form factor make it suitable for installation in ruggedized industrial PCs mounted in control room enclosures adjacent to the process floor.

Packaging & Material Handling: High-speed packaging lines use the DN3-PCI-2 to coordinate servo drives, pneumatic actuators, and barcode scanners over a single DeviceNet trunk, reducing wiring complexity and enabling rapid format changeovers through software-configurable I/O mapping.

Q1: Is the SST DN3-PCI-2 compatible with both master and slave DeviceNet configurations, and can it coexist with other DeviceNet masters on the same network? A: Yes. The DN3-PCI-2 supports both master (scanner) and slave (adapter) operating modes, configurable via the SST SDK software. In multi-master architectures, the card implements the DeviceNet Group 2 Only Slave protocol for slave mode and the UCMM (Unconnected Message Manager) for master mode, allowing it to coexist with other masters such as Allen-Bradley 1756-DNB scanner modules on the same trunk, provided MAC IDs are uniquely assigned and bus loading is within specification.

Q2: What are the installation and commissioning requirements for integrating the DN3-PCI-2 into an existing ControlLogix or CompactLogix architecture? A: Installation requires a standard PCI slot in the host PC or industrial workstation. After physical installation, the SST SDK driver must be installed and the card configured using the SST Configuration Utility, where the MAC ID, baud rate, and I/O connection parameters are defined. For ControlLogix integration, the EDS (Electronic Data Sheet) file for the DN3-PCI-2 is imported into RSNetWorx for DeviceNet, enabling the ControlLogix controller to recognize the card as a network node. Commissioning includes bus termination verification, node address conflict scanning, and a full I/O connection test at the target baud rate before going live.

Q3: What does the 12-Month Warranty cover, and what is the stock and lead time situation for the SST DN3-PCI-2? A: NANKMOS provides a 12-Month Warranty on the SST DN3-PCI-2, covering manufacturing defects and functional failures under normal operating conditions. Each unit undergoes pre-shipment functional testing to verify PCI bus enumeration, DeviceNet network initialization, and loopback communication integrity. Stock is maintained for fast global dispatch, with typical lead times of 3–7 business days for standard destinations.
