Description
Product Overview
The ALSTOM 029.362754, associated in available parts records with the SST-PFB3-VME2, is identified as an industrial communication interface card for VME-based control systems. Its reported application is connecting a VME controller architecture to a PROFIBUS DP field network. This type of interface allows controller-side equipment to exchange data with compatible network devices, supporting communication between automation hardware and distributed control components.
The distinction between the part number and the board manufacturer is important. The number 029.362754 appears in ALSTOM parts inventories, while the SST-PFB3-VME2 designation is associated with an SST communication card. This may reflect an equipment-specific or procurement part-number relationship, but the available records do not establish the complete original equipment configuration or prove that every board carrying the SST model designation is interchangeable with the ALSTOM-numbered assembly.
When evaluating the ALSTOM 029.362754, engineers should check the PCB manufacturer’s label, board revision, VME connector arrangement, PROFIBUS connector, and any configuration switches or firmware identifiers. The host rack’s VME requirements and the network’s PROFIBUS settings must also be considered. A card that fits the rack may still fail to communicate if its hardware revision, firmware, bus configuration, or network parameters differ from the installed unit.
For maintenance procurement, preserve the original configuration and network settings before removing the existing card. Confirm communication with the intended PROFIBUS devices during commissioning, and check diagnostic indications under normal operating conditions. Exact bus speed, channel count, supported operating modes, power consumption, and environmental ratings for this specific part number remain unverified.
Product Introduction (Non-Templated)
Communication faults in an established VME control system can be difficult to isolate. The problem may originate in the interface card, the PROFIBUS cabling, network termination, node configuration, or the host controller. Replacing the board without preserving the original network parameters can introduce a second fault during maintenance.
The 029.362754 is associated with the SST-PFB3-VME2 communication card. Before installation, compare the original and replacement board labels, revision markings, connectors, and configuration settings. Verify network communication and controller diagnostics before releasing the equipment back to operation.

Frequently Asked Questions
Q1: What is ALSTOM 029.362754 used for?
It is associated with the communication interface card. Available records identify it as a VME-based communication component with a PROFIBUS network association.
Q2: Is 029.362754 a PROFIBUS DP interface card?
That is the strongest available identification. However, the exact supported PROFIBUS modes, channel count, baud-rate range, and firmware capabilities have not been confirmed for this part number.
Q3: Is the same as ALSTOM 029.362754?
A product listing explicitly associates the two designations. Confirm the actual PCB label and revision before treating the association as sufficient proof of interchangeability.
Q4: Can I hot-swap the 029.362754?
Hot-swap capability is not verified. Do not remove the card while the rack is energized unless the system documentation explicitly permits live replacement. Follow the VME rack’s shutdown and ESD procedures.
Q5: Does this module support firmware v3.1?
No verified firmware compatibility information is available. Check the installed board’s firmware identification and the host system’s approved hardware and software configuration.
Q6: What should I check before replacing the communication card?
Compare the board model, part number, revision, VME connector, network connector, configuration switches, and firmware. Record the original PROFIBUS node address and communication parameters where applicable.
Q7: How should the replacement be tested?
Check rack recognition, board diagnostics, network status, PROFIBUS communication, and data exchange with the connected devices. Confirm that the host controller receives the expected process data and reports no new communication faults.
Procurement recommendation: Use the description ALSTOM 029.362754 / communication interface card as a provisional identification. Do not advertise unverified analog/digital I/O functions, 24VDC supply, hot-swap capability, or specific network speeds. A photograph of the board label and connector side would help confirm the exact assembly and revision.
