Product Overview
The SST 5136-PFB-VME is a VMEbus interface card that connects a VME-based host computer, motion controller, or programmable controller to PROFIBUS networks. It supports PROFIBUS DP Master, DP Slave, and FDL Layer 2 communication, with these operating modes capable of running simultaneously. The card uses an onboard Intel i960 processor to handle PROFIBUS protocol processing and data exchange with the host through shared memory. Standard PROFIBUS baud rates from 9.6 Kbaud through 12 Mbaud are supported, making the interface suitable for legacy industrial automation systems that rely on VMEbus computing platforms. The hardware provides onboard RAM and flash storage for application software and PROFIBUS configuration data. Personally, I would treat this as a legacy communication component and verify the host VME architecture, driver version, firmware, and configured network role before replacement.

Installation and Maintenance — 5136-PFB-VME
Before installation, verify the VME chassis slot, address-switch configuration, memory mapping, interrupt settings, and PROFIBUS network parameters. The card requires its PROFIBUS software module and appropriate configuration before normal network operation; configuration can be loaded through the serial port or from host software.
During maintenance, inspect the VME edge connector, PROFIBUS connector, jumpers, switches, and configuration-port connection. Confirm that firmware and configuration data correspond to the existing host application. For legacy systems, keeping a backup of the working configuration is particularly valuable because software compatibility can be as important as the hardware itself.
Product Warranty — 5136-PFB-VME
Warranty coverage depends on the supplier and unit condition, including new, unused surplus, refurbished, or repaired stock. Before procurement, confirm functional-test status, firmware revision, serial-number traceability, warranty period, and return conditions.
The SST 5136-PFB-VME is a specialized legacy PROFIBUS interface for VMEbus systems. Exact compatibility should be confirmed at the hardware, firmware, driver, and network-configuration levels before replacement.
