Frequently Asked Questions

1. How does the card handle DeviceNet bus arbitration?

   The SST-DN3-PCI-1-E follows the DeviceNet CSMA/CD protocol. Each node checks the bus before sending data and yields to higher-priority messages, ensuring deterministic communication.

2. Can it operate in a multi-master DeviceNet network?

   Yes, the card supports multi-master operation and can coexist with other masters without communication conflicts.

3. Maximum number of nodes supported?

   Supports up to 64 nodes per DeviceNet network segment. Additional nodes require network repeaters or multiple cards.

4. Does it support both explicit and I/O messaging?

   Yes. Explicit messaging for configuration/diagnostics and I/O messaging for cyclic data transfer are handled simultaneously without performance loss.

5. How is it initialized in Windows and Linux PCs?

   In Windows, initialization uses Woodward drivers or DeviceNet configuration software. In Linux, PCI DeviceNet drivers with proper configuration (baud rate, node ID, timeouts) are required.

6. What level of galvanic isolation does it provide?

   1.5 kV isolation exists between the PCI bus and DeviceNet, protecting the host PC from ground loops and voltage spikes.

7. Can it communicate with legacy DeviceNet devices?

   Yes, compatible with ODVA DeviceNet protocol 2.0 and above, supporting most older DeviceNet nodes.

8. How are communication errors detected and reported?

   Errors such as bus-off, CRC failures, or node non-response are indicated by LEDs and reported via software diagnostics.

9. Does it support redundant networks with failover?

   The card itself is single-channel. Redundancy requires two cards on separate DeviceNet segments, with master software managing failover.

10. Which tools are compatible for monitoring DeviceNet traffic?

    Compatible tools include Woodward DeviceNet Explorer, third-party DeviceNet sniffers, and ODVA-compliant network analyzers for real-time monitoring.
