PROFIBUS DP Master/Slave Solution – SST SST-PB3-VME-2-E | PB3 Series
The SST SST-PB3-VME-2-E is a high-performance PROFIBUS DP communication board designed for VME bus-based industrial control systems. Engineered for demanding automation environments, this board enables seamless PROFIBUS DP master or slave communication within VME chassis, making it the preferred choice for system integrators and control engineers working with distributed I/O, drives, and field devices.
Where This Product Is Used
The SST-PB3-VME-2-E is deployed across a wide range of industrial sectors where VME-based controllers must communicate with PROFIBUS DP field devices:
- Automotive Manufacturing: Robot cell controllers and body-in-white assembly lines using VME-based PLCs communicating with PROFIBUS-enabled servo drives and I/O blocks.
- Oil & Gas / Petrochemical: DCS systems in hazardous-area control rooms where VME rack controllers interface with remote PROFIBUS field instruments (pressure transmitters, valve positioners).
- Power Generation & Utilities: Turbine control and substation automation systems requiring deterministic PROFIBUS DP communication from VME-hosted controllers.
- Semiconductor Fabrication: Process equipment controllers (etch, CVD, lithography) using VME platforms to coordinate PROFIBUS-connected actuators and sensors.
- Water & Wastewater Treatment: SCADA-integrated VME controllers managing PROFIBUS DP pump drives, flow meters, and remote I/O stations.
- Railway & Transportation: Trackside and rolling-stock control systems where VME ruggedness meets PROFIBUS field device ecosystems.

Why Engineers Specify This Model
- Proven VME Integration: Native VMEbus interface eliminates the need for external gateways, reducing latency and single points of failure in the communication chain.
- Dual-Port RAM Architecture: Enables high-speed, deterministic data exchange between the host CPU and PROFIBUS network without DMA contention.
- Master & Slave Flexibility: A single board supports both DP Master Class 1 and DP Slave modes, reducing spare-parts inventory for multi-role deployments.
- Mature Ecosystem: SST PB3 series boards have been deployed in production environments for over two decades, with extensive third-party driver support (VxWorks, Linux, Windows).
- Rugged Industrial Design: Conformal-coat option and wide operating temperature range suit harsh plant-floor and outdoor enclosure installations.
- Long-Term Availability: Konmask maintains sourced stock of legacy SST VME boards to support ongoing maintenance and system life-extension projects.
