- Test & measurement systems with Profibus field device integration
System Compatibility
- VMEbus Standard: IEEE 1014 (VME64 compatible)
- Operating Systems: OS-9, VxWorks, LynxOS, Linux (with driver support)
- Profibus Conformance: EN 50170 Vol. 2, IEC 61158 Type 3
- Compatible CPUs: Nautibus VME CPU boards; third-party VME SBCs with A24/D16 or A32/D32 access
- Configuration Tools: Profibus configuration tools supporting GSD files (e.g., Siemens STEP 7, Sycon.net)
Selection Guide
Use the following criteria to confirm the VME-PROF-M is the right choice — or to identify the best replacement:
- Step 1 – Confirm bus type: Verify your rack uses VMEbus (IEEE 1014). If using CompactPCI or PCI, a different module family is required.
- Step 2 – Confirm role: VME-PROF-M is a DP Master. If you need a DP Slave, select the VME-PROF-S or equivalent.
- Step 3 – Count slaves: Confirm your slave count does not exceed 125 nodes per master.
- Step 4 – Check baud rate: Ensure your network baud rate (up to 12 Mbps) is within spec.
- Step 5 – OS/driver support: Confirm driver availability for your real-time OS (OS-9, VxWorks, Linux).
- Step 6 – Slot availability: Verify one free 6U VME slot is available in your chassis.

Replacement & Compatibility FAQ
Q: Is the VME-PROF-M still in production?
A: The VME-PROF-M is a legacy product. Availability is subject to stock. Contact us to confirm current inventory.
Q: Can I use a Hilscher CIF50-PB as a direct replacement?
A: The CIF50-PB offers equivalent Profibus DP Master functionality on VMEbus and is a widely accepted replacement. Driver migration may be required.
Q: Does the VME-PROF-M support Profibus PA?
A: No. The VME-PROF-M supports Profibus DP only. A DP/PA coupler (e.g., Siemens DP/PA Link) is required for PA segments.
Q: What is the maximum cable length for Profibus DP at 12 Mbps?
A: At 12 Mbps, the maximum segment length is 100 m. Use repeaters for longer runs.
Q: Can I use this module with a non-Nautibus VME CPU?
A: Yes, provided the CPU supports A24/D16 or A32/D32 VME access and a compatible driver is available for your OS.
