Description
Description
The Woodward 5136-DNP-CPCI is a high-performance SST DeviceNet interface card engineered for CompactPCI (cPCI) industrial bus architectures. This communication module facilitates seamless integration between host controllers and DeviceNet networks, enabling the exchange of real-time I/O data and explicit messaging. By offloading complex protocol management from the main system CPU, the 5136-DNP-CPCI ensures superior network performance, reduced communication latency, and enhanced system stability in mission-critical automation environments.
Features
- CompactPCI (cPCI) form factor for secure mechanical fit and high-speed backplane connectivity.
- Supports DeviceNet Master and Slave configurations as a Group 2 Client/Server.
- Onboard processor manages the DeviceNet stack, supporting Polled, Cyclic, and Change-of-State (COS) connections.
- Data transmission rates selectable at 125, 250, or 500 kbps.
- Integrated 500 VDC optical isolation to protect host systems from fieldbus voltage surges and ground loops.
- Onboard status LEDs for real-time diagnostics of bus power and network health.
Applications
This interface card is primarily utilized in turbine control systems, automotive assembly lines, and heavy industrial processing plants where deterministic, high-speed fieldbus communication is required to minimize downtime.

Installation Guidelines
- Ensure the host system is powered down before inserting or removing the 5136-DNP-CPCI module into the cPCI backplane.
- Handle the card by its edges and utilize ESD-safe practices to prevent damage to sensitive electronic components.
- Ensure the module is fully seated in the cPCI slot and the front panel screws are tightened to provide proper grounding and mechanical stability.
- Route DeviceNet fieldbus cabling away from high-voltage power lines and sources of electromagnetic interference (EMI) to maintain signal integrity.
- Verify bus power and network termination settings according to the DeviceNet physical layer requirements.
FAQ
What is the primary function of the 5136-DNP-CPCI?
The 5136-DNP-CPCI acts as a communication bridge, allowing a host controller on a CompactPCI bus to communicate with devices on a DeviceNet network by handling the protocol stack independently.
Does this card support both Master and Slave modes?
Yes, the module is designed to operate as a Group 2 Client/Server, supporting both Master and Slave configurations for flexible network integration.
What is the purpose of the optical isolation?
The 500 VDC optical isolation provides a safety barrier between the industrial DeviceNet fieldbus and the host system, protecting the controller from electrical surges or ground loop issues originating in the field.
