SST 5136-PFB-PCI — PROFIBUS-DP Master Communication Card | 5136-PFB Series
Engineering Background
The SST 5136-PFB-PCI is a high-performance PROFIBUS-DP Master communication card designed for PCI bus architectures. Developed by SST (Woodhead / Molex), the 5136-PFB series has been a trusted fieldbus interface solution in industrial automation for over two decades. It enables PC-based control systems, SCADA hosts, and DCS workstations to communicate natively with PROFIBUS-DP slave devices at up to 12 Mbps — without requiring a dedicated PLC CPU.
Product Positioning
Targeted at automation engineers who need a reliable, software-configurable PROFIBUS-DP master interface for Windows-based industrial PCs, the 5136-PFB-PCI bridges legacy fieldbus infrastructure with modern PC-based control architectures. It is widely deployed in automotive, process, and discrete manufacturing environments where PROFIBUS-DP remains the dominant fieldbus standard.

Engineering Advantages
- Protocol Offload Architecture — Onboard microcontroller handles all PROFIBUS-DP timing and token management, freeing the host CPU for application logic
- Dual-Port RAM Interface — Low-latency, deterministic data exchange between host application and fieldbus network
- Auto Baud Rate Detection — Simplifies commissioning on existing networks without manual configuration
- Full DP Master Class 1 Compliance — Supports cyclic data exchange, acyclic services (DPV1), and diagnostic reads
- Mature SDK Ecosystem — Well-documented DLL/API with sample code for C, C++, VB, and LabVIEW
- Universal PCI Slot — 5V/3.3V signaling compatibility ensures broad industrial PC motherboard support
System Architecture & Signal Flow
The 5136-PFB-PCI installs into any available PCI slot on the host industrial PC. The onboard microcontroller autonomously manages the PROFIBUS-DP token ring and cyclic I/O exchange with up to 125 slave nodes. Process data is written to and read from the dual-port RAM by the host application via the SST DLL API — achieving deterministic cycle times independent of Windows OS scheduling jitter. The DB-9 connector interfaces directly to the PROFIBUS cable (termination resistors must be enabled at network endpoints per EN 50170).
Signal path: Host Application → DLL API → Dual-Port RAM → Onboard MCU → PROFIBUS-DP Network → Slave Devices

Technical FAQ
Q: Is the 5136-PFB-PCI compatible with Windows 10 64-bit?
A: Yes. SST provides 64-bit drivers for Windows 7, 8, and 10. Confirm the driver version matches your OS build before installation.
Q: Can this card operate as a PROFIBUS-DP slave?
A: No. The 5136-PFB-PCI is a DP Master (Class 1) only. For slave functionality, refer to the SST 5136-PFB-PCI-SLAVE variant.
Q: What is the maximum cable length at 12 Mbps?
A: Per EN 50170, maximum segment length at 12 Mbps is 100 m. Use PROFIBUS-certified cable (Type A) and proper termination.
Q: Does it support PROFIBUS-PA?
A: No. This card supports PROFIBUS-DP only. PA requires a DP/PA coupler/link device.
Q: Is GSD file configuration required?
A: Yes. Import slave GSD files into the SST PROFIBUS Configurator to define the I/O map before going online.
