Product Details

SST-DN3-PCI-2 Product Description

The Woodward SST-DN3-PCI-2 is a high-performance DeviceNet Master/Slave PCI interface card engineered for seamless integration into industrial control architectures. Designed to bridge host PC-based control platforms with DeviceNet fieldbus networks, this card delivers deterministic communication, robust I/O scanning, and reliable node management across complex automation topologies. Whether deployed in discrete manufacturing, process control, or energy management systems, the SST-DN3-PCI-2 provides the communication backbone that enables coordinated, real-time data exchange between the control layer and field devices.

In modern industrial automation, no component operates in isolation. The SST-DN3-PCI-2 is purpose-built to function as a critical communication node within a layered control architecture — connecting the supervisory control layer to the physical I/O layer through a standardized, open DeviceNet protocol. Its dual Master/Slave capability allows it to serve both as a network master polling remote I/O modules and as a slave responding to upstream SCADA or DCS commands, making it exceptionally versatile across multi-tier control hierarchies.

The SST-DN3-PCI-2 achieves its full potential when deployed within a cohesive, multi-layer automation platform. In a typical control cabinet architecture, the card is installed in an industrial PC or embedded controller running a real-time OS, where it manages DeviceNet I/O scanning at deterministic cycle rates. At the control layer, it interfaces directly with Allen-Bradley ControlLogix or CompactLogix PLCs acting as upstream supervisory controllers, receiving process data via EtherNet/IP or ControlNet and translating commands down to DeviceNet field devices.

At the I/O layer, the SST-DN3-PCI-2 polls Allen-Bradley 1769-SDN DeviceNet Scanner modules and 1734-ADN POINT I/O DeviceNet Adapters, aggregating discrete and analog signals from sensors, actuators, and motor starters distributed across the production floor. For power distribution within the control cabinet, Phoenix Contact QUINT-PS/1AC/24DC/10 power supplies provide stable 24 VDC rail power to the DeviceNet trunk line and field devices, ensuring voltage stability under variable load conditions.

Communication layer redundancy is enhanced by pairing the SST-DN3-PCI-2 with Moxa NPort 5150 serial device servers for legacy RS-232/485 device integration, and Advantech EKI-7706G industrial Ethernet switches for upstream network segmentation. In applications requiring signal conditioning, Phoenix Contact MCR-SL signal isolators are deployed between the DeviceNet trunk and analog field instruments to eliminate ground loops and ensure signal integrity across long cable runs.

For HMI integration, Siemens SIMATIC TP700 Comfort Panel HMIs connected via PROFINET to the supervisory PLC provide operator visualization of DeviceNet node status, I/O diagnostics, and network health — with the SST-DN3-PCI-2 supplying real-time node data upstream. In drive control applications, Rockwell PowerFlex 525 AC drives equipped with DeviceNet communication modules are scanned directly by the SST-DN3-PCI-2, enabling speed reference, torque control, and fault status monitoring within a single network scan cycle.

Backplane and rack integrity is maintained through Allen-Bradley 1756-A10 ControlLogix chassis housing redundant CPU and communication modules, while Weidmuller WDU 2.5 terminal blocks provide reliable field wiring termination within the control cabinet. This fully integrated architecture — spanning control, I/O, communication, power, HMI, drive, and termination layers — demonstrates the SST-DN3-PCI-2's role as a foundational communication element in scalable, maintainable industrial automation systems.

Discrete Manufacturing & Assembly Lines: In automotive body shop and electronics assembly environments, the SST-DN3-PCI-2 manages DeviceNet networks connecting pneumatic valve manifolds, photoelectric sensors, proximity switches, and servo drive feedback modules. Its high-speed polling ensures sub-10ms I/O response times critical for synchronized multi-axis assembly operations and vision-triggered reject systems.

Power Generation & Energy Facilities: In thermal power plant auxiliary systems and substation automation, the card integrates DeviceNet-enabled motor protection relays, switchgear position feedback modules, and transformer tap-changer controllers into the plant DCS. Its optical isolation prevents ground fault propagation from high-voltage environments into the control PC, protecting data integrity during switching transients.

Petrochemical & Process Control: In refinery and chemical plant applications, the SST-DN3-PCI-2 connects DeviceNet I/O blocks monitoring flow transmitters, pressure sensors, and solenoid valve positioners within hazardous area control loops. Its deterministic scan cycle supports SIL-rated safety instrumented system (SIS) architectures where consistent I/O response is a functional safety requirement.

Water Treatment & Municipal Infrastructure: In SCADA-controlled water treatment plants, the card enables centralized monitoring of distributed pump stations, valve actuators, and flow meters across DeviceNet segments. Its slave mode capability allows the host PC to respond to upstream SCADA polling while simultaneously managing local field device networks.

Mining & Metallurgy: In conveyor control systems and ore processing plants, the SST-DN3-PCI-2 provides robust DeviceNet communication in high-vibration, high-dust environments. Its wide operating temperature range and optical isolation make it suitable for surface and underground control rooms where environmental conditions challenge standard industrial hardware.

Packaging & Material Handling: In high-speed packaging lines and palletizing systems, the card's fast I/O scan rates and multi-node management capability support coordinated control of servo drives, pneumatic actuators, label applicators, and checkweighers — all networked on a single DeviceNet segment managed by the SST-DN3-PCI-2.

Q1: Is the SST-DN3-PCI-2 compatible with both Allen-Bradley and third-party DeviceNet devices, and can it coexist with other fieldbus cards in the same host PC? A: Yes. The SST-DN3-PCI-2 is fully compliant with the ODVA DeviceNet specification, ensuring interoperability with any certified DeviceNet device regardless of manufacturer — including Allen-Bradley, Omron, Turck, Balluff, and Pepperl+Fuchs nodes. Multiple SST-DN3-PCI-2 cards can be installed in the same host PC to manage independent DeviceNet segments, and they coexist without conflict with other PCI-based fieldbus cards (Profibus, ControlNet) provided adequate PCI slots and IRQ resources are available. The SST Configuration Utility supports multi-card installations with independent network configuration per card.

Q2: What are the key considerations for integrating the SST-DN3-PCI-2 into an existing PLC/DCS architecture, and how is network commissioning performed? A: Integration requires defining the card's MAC ID (node address, 0–63), configuring the baud rate to match the existing DeviceNet segment (125/250/500 kbps), and building an Electronic Data Sheet (EDS)-based I/O connection table using the SST Configuration Utility or a compatible network configuration tool such as RSNetWorx for DeviceNet. For DCS integration, the card operates in slave mode, responding to the DCS scanner's explicit messaging or polled I/O connections. Commissioning involves verifying node enumeration, checking I/O data mapping against the PLC tag database, and validating scan cycle times against the application's control loop requirements. NANKMOS provides pre-shipment functional testing and configuration documentation upon request.

Q3: What does the 12-Month Warranty cover, and what is the typical lead time and supply availability for the SST-DN3-PCI-2? A: The NANKMOS 12-Month Warranty covers manufacturing defects, functional failures under normal operating conditions, and firmware-related malfunctions identified within 12 months of shipment. It does not cover damage resulting from incorrect installation, overvoltage events, or unauthorized modification. The SST-DN3-PCI-2 is maintained in stock at NANKMOS for fast global shipping, with typical lead times of 3–7 business days for standard orders. Expedited shipping options are available for urgent maintenance and emergency replacement scenarios.
