Product Short Description
Product Name: SST 5136‑PFB Profibus Interface Card (family designation covering VME, PCI variants)
Product Introduction: A family of Profibus‑DP interface cards built around an onboard Intel i960 processor with local RAM and flash. Depending on the specific suffix (‑VME, ‑PCI, ‑104), the card mounts on the corresponding host bus and serves as a Profibus‑DP master, slave, or FDL (layer‑2) message handler simultaneously.
Description
Technical Specifications:
-
Processor: Onboard Intel i960
-
Local RAM: 512 Kbytes
-
Shared RAM: 256 Kbytes (linear mode, or paged 16 × 16 KB under host control)
-
Flash Memory: 512 Kbytes segmented flash for program and configuration storage
-
Profibus Baud Rates: 9.6K, 19.2K, 93.75K, 187.5K, 500K, 750K, 1.5M, 3M, 6M, 12M
-
Supported Roles: DP‑Master, DP‑Slave, FDL layer‑2 messaging (all simultaneously)
-
Maximum DP Slaves: Up to 96 DP slaves (requires repeaters if more than 32)
Functional Features:
-
Multi‑role operation (Master/Slave/FDL) at the same time
-
Onboard flash stores Profibus configuration (e.g., *.bss binary file)
-
VME variant provides five registers in short address space for card control
Application Scenarios: Remote I/O solutions for GE Fanuc PACSystems RX7i and Series 90‑70 PLC central racks (VME variant); Profibus‑DP development and configuration master card in industrial PCs (PCI variant).
Working Principle: The i960 processor handles the Profibus protocol stack and writes formatted data into shared RAM; the host reads/writes shared RAM via its bus interface (VME short/extended address space or PCI BAR).
Installation Requirements:
-
VME version: Insert into the central rack of a GE 90‑70 or RX7i PLC; set the VME short base address via DIP switch S1 positions 1‑6; ensure no empty slot between the card and the CPU.
-
PCI version: Insert into a PCI slot; download the configuration binary (*.bss or *.2bf) via serial port using terminal software.
Usage Notes: Configuration must be generated with SST Profibus Configuration software (or COMPROFIBUS) and downloaded as a binary file; when the number of slaves exceeds 32, Profibus repeaters are mandatory.
