SST 5136-DNP-CPCI CompactPCI Interface – 125/250/500 Kbps DeviceNet Communication

Brand ABB

Model SST 5136-DNP-CPCI

Product Overview

The SST 5136-DNP-CPCI is a high-performance CompactPCI (cPCI) interface card engineered to connect industrial computers, embedded controllers, and HMI systems directly to DeviceNet automation networks. Manufactured by SST (Woodhead Software & Electronics, now part of Molex), the SST 5136-DNP-CPCI represents a specialized class of communication module in which the entire DeviceNet protocol stack is executed in dedicated onboard hardware, offloading CAN bus traffic management and cyclic I/O messaging from the host CPU. This architectural decision enables real-time control performance in automated assembly lines, semiconductor fabrication equipment, and high-speed packaging machinery where deterministic communication is essential.

At its core, the SST 5136-DNP-CPCI features a high-performance 40 MHz processor with 512 KB of RAM and 512 KB of Flash memory, complemented by 256 KB of shared RAM for efficient data exchange with the host system. The card operates as a Group 2 DeviceNet Master, Slave, or both simultaneously, supporting UCMM (Unconnected Message Manager) and dynamic explicit connections across Groups 1, 2, and 3. This flexibility allows the SST 5136-DNP-CPCI to serve as a centralized I/O scanner in one application while functioning as a device-level slave in another, adapting to diverse industrial network topologies without hardware modification.

The SST 5136-DNP-CPCI is particularly valued for its role as a critical spare component in legacy CompactPCI-based control systems. As industrial computing platforms migrate toward PCI Express, the CompactPCI form factor remains prevalent in installed base equipment across semiconductor manufacturing, high-speed packaging, and embedded process control. When a DeviceNet communication card fails in these systems, the SST 5136-DNP-CPCI provides a verified replacement path that preserves existing host software, driver infrastructure, and network configurations, avoiding the need for complete controller rack replacement or application rewrite.

Main Features and Advantages

Hardware-Executed DeviceNet Protocol: The SST 5136-DNP-CPCI distinguishes itself from generic multi-port communication cards by executing the entire DeviceNet protocol stack in dedicated onboard hardware. The 40 MHz processor and 512 KB of RAM handle CAN bus arbitration, message filtering, and cyclic I/O data exchange independently of the host CPU. This offloading capability dramatically reduces host processor load, enabling the host system to dedicate its resources to application-level control logic rather than network protocol management. In high-throughput applications, this architectural advantage translates directly to faster scan times and more deterministic control performance.

Simultaneous Master and Slave Operation: The SST 5136-DNP-CPCI supports the concurrent execution of Group 2 Client (Master) and Server (Slave) operations, a capability rarely found in single-card DeviceNet interfaces. This dual-role functionality enables the card to serve as both an I/O scanner for slave devices and a data server to a higher-level supervisory controller, bridging network segments without additional gateway hardware. For system integrators, this flexibility simplifies architecture design and reduces component count in complex DeviceNet installations.

Complete DeviceNet Feature Set with UCMM Support: The SST 5136-DNP-CPCI implements full DeviceNet messaging capabilities including Polled, Strobed, Change of State (COS), Cyclic, and Explicit Messaging. UCMM (Unconnected Message Manager) capability ensures compatibility with modern DeviceNet devices that rely on unconnected messaging for configuration and diagnostics. Dynamic explicit connections across Groups 1, 2, and 3 provide the flexibility to communicate with virtually any DeviceNet-compliant device regardless of its connection model.

Open Documented Memory Map with Example Code: SST provides an open documented memory map interface for the SST 5136-DNP-CPCI, accompanied by example C source code and Windows 32-bit DLLs and drivers. This transparency enables system integrators to develop custom applications tailored to specific control requirements without reverse-engineering proprietary interfaces. The availability of source-level examples accelerates development cycles and reduces integration risk for OEM and end-user projects alike.

Network Isolation and Diagnostic Visibility: The SST 5136-DNP-CPCI incorporates 500V opto-isolated CAN transceiver circuitry, protecting both the cPCI backplane and the host computer from electrical transients and ground faults on the DeviceNet network. Front-panel MOD/NET status LEDs provide immediate visual confirmation of module health and network activity, enabling technicians to diagnose communication issues without requiring external test equipment or software tools.
