Why Engineers Specify This Model
- Dual-Channel Architecture: Two independent PROFIBUS DP ports allow a single card to manage separate field networks or provide redundant communication paths — reducing slot count and system complexity.
- Full DP Master/Slave Flexibility: Configurable as Class 1 or Class 2 DP Master, or as a DP Slave, making it adaptable across diverse system topologies without hardware changes.
- High-Speed Determinism: Supports baud rates up to 12 Mbps with deterministic cycle times critical for motion control and process synchronization applications.
- VME Ecosystem Compatibility: Designed for seamless integration into existing VME chassis without requiring backplane modifications or additional interface hardware.
- Proven Field Reliability: Widely deployed in mission-critical industrial environments with a long service history, reducing qualification risk for brownfield upgrades.
- Software Driver Ecosystem: Supported by SST’s established driver libraries for major RTOS platforms, shortening integration timelines for engineering teams.

Application-Specific FAQ
Q: Can the SST-PB3-VME-2 operate as both a PROFIBUS Master and Slave simultaneously on its two channels?
A: Yes. Each channel is independently configurable. One channel can be set as a DP Master while the second operates as a DP Slave, enabling gateway or bridge topologies within a single card.
Q: Is this card compatible with modern VME chassis, or only legacy systems?
A: The SST-PB3-VME-2 conforms to the IEEE 1014-1987 VMEbus standard and is compatible with any compliant 6U VME chassis, including modern chassis from Elma, Pixus, and Schroff.
Q: What software is required to configure and operate this card?
A: SST provides driver libraries and configuration utilities for VxWorks, QNX, and LynxOS. GSD files are available for integration with PROFIBUS configuration tools such as Siemens STEP 7 or TIA Portal in mixed-network environments.
Q: Can this card replace an SST-PB3-VME-1 (single-channel version) in an existing system?
A: In most cases, yes — the dual-channel SST-PB3-VME-2 is backward-compatible with single-channel applications. Verify slot dimensions and driver version compatibility before substitution.
Q: Do you provide acceptance test reports (ATR) or functional test certificates?
A: Acceptance testing is available as a value-added service. Contact [email protected] to discuss test scope and pricing prior to order.
Q: What is the typical application in an oil & gas DCS upgrade project?
A: In brownfield DCS upgrades, the SST-PB3-VME-2 is commonly used to retain existing VME-based controller hardware while migrating field devices to PROFIBUS DP, avoiding full controller replacement and reducing project cost and risk.
