4. Product Introduction & Supply Chain Strategy

The SST 5136-PFB family represents one of the most widely deployed industrial fieldbus interface architectures in factory automation. Designed to bridge host computing buses (PCI, VME, ISA, PC/104) directly to RS-485 Profibus DP networks, each 5136-PFB module features an onboard microprocessor that executes network token passing, cycle timing, and error handling independently of the host CPU.

This product line is offered as Brand New Surplus. Units are not used, not pulled from decommissioned systems, and not refurbished. All cards undergo complete bus interface diagnostics, memory bus validation, and RS-485 port transceiver verification prior to dispatch.

In automated steel mills, automotive assembly plants, and chemical processing facilities, an interface card failure completely isolates the main control station from remote I/O drives and motor starters. Sourcing verified New Surplus SST 5136-PFB boards provides a direct direct-fit replacement path without requiring host OS driver updates or system migration.

5. Installation & Configuration Guide

ESD & Backplane Voltage Hazard

Electrostatic discharge can destroy RS-485 transceiver components and bus edge connectors. Always wear a grounded anti-static wrist strap and disconnect all power to the host system prior to card installation or removal.

1

Host Power Isolation

Prerequisite

1.Host Power Isolation:Prerequisite.

Power down the host PC or VME chassis. Disconnect the main AC power cord to prevent bus voltage spikes during card insertion.

2

Address & Slot Alignment

Hardware Setup

2.Address & Slot Alignment:Hardware Setup.

For ISA/PC104 variants, set base memory DIP switches and IRQ jumpers. For PCI/cPCI variants, align the card edge with an available expansion slot and seat firmly into the connector.

3

Profibus Cable Attachment

Wiring

3.Profibus Cable Attachment:Wiring.

Attach a shielded DB9 Profibus cable to the front panel connector. Ensure line termination switches (220-ohm resistors) are enabled on the physical end nodes of the segment.

4

Scan List Programming

Software Config

4.Scan List Programming:Software Config.

Apply power to the host system. Launch the SST Profibus Configuration Utility, import GSD files for all slave devices, assign station addresses, and download the binary scan map to the card’s EEPROM/DPRAM.

5

Diagnostic LED & Data Run Check

Verification

5.Diagnostic LED & Data Run Check:Verification.

Confirm that the front-panel status LEDs display solid green (RUN / COMM). Verify in host software that cyclic I/O data updating matches field sensor states with zero parity or frame errors.

6. System Compatibility & Maintenance Notes

The SST 5136-PFB series integrates across various industrial computing environments:

  • Operating System Support: Windows (3.1/95/98/NT/2000/XP/7/10 via SST drivers), VxWorks, QNX, Linux, and DOS.
  • GSD File Integration: Fully compatible with standard Profibus GSD configuration files from any device vendor (Siemens, ABB, Danfoss, Schneider).
  • Multi-Master Networks: Capable of coexisting on multi-master Profibus networks using token-ring passing logic.

7. Frequently Asked Questions (FAQ)

Q: Which specific form factor is the standard “5136-PFB”?

A: “5136-PFB” refers to the core module family. You must specify the bus suffix for your hardware slot: -PCI for standard PCI slots, -VME for VMEbus racks, -ISA for legacy PCs, or -104 for stackable embedded systems.

Q: Is this SST 5136-PFB card brand new or refurbished?

A: This product is a Brand New Surplus unit. It is not used, not pulled from a decommissioned plant, and not refurbished. All boards undergo full electrical diagnostic testing.

Q: Can the 5136-PFB operate as both a Profibus Master and Slave simultaneously?

A: Yes. The card supports multi-protocol modes, allowing it to function as a Class 1 DP Master to local field I/O while simultaneously acting as a DP Slave to a higher-level host PLC.

Q: What warranty applies to this New Surplus interface card?

A: We supply this card with a full 1-year functional replacement warranty from the date of shipment to ensure plant operational reliability.
