Overview Manuals Specifications Programming & Configuration Application Scenarios Diagnostics

Features:

  • Operates as an independent PROFIBUS DP-Master or configurable DP-Slave without requiring PROFIBUS software on the host VMEbus CPU.
  • Combines a 32-bit processor, PBM-ASIC, dualport RAM, and onboard Flash EPROM for reliable high-speed PROFIBUS communication.
  • Supports cost-effective integration of distributed PROFIBUS I/O modules and synchronized drive systems with microsecond-level DP-V2 cycle control.
Nautibus VME-PROF-M provides an efficient communication bridge between VMEbus platforms and PROFIBUS field devices used throughout industrial automation systems. The board enables decentralized I/O architectures while reducing dependence on conventional VMEbus I/O hardware. Compatibility with both Mono-Master and Multi-Master configurations offers flexibility for a wide variety of control applications.

The interface combines hardware-based protocol processing with independent firmware execution, allowing PROFIBUS communication to continue without additional software resources from the host CPU. Built-in dualport RAM creates a fast data exchange area between the VMEbus processor and distributed field devices, while EEPROM retains configuration settings for rapid startup after reset. The integrated RS232 interface further simplifies system commissioning and diagnostics.

Nautibus VME-PROF-M is particularly well suited for industrial control cabinets, production lines, motion control systems, and distributed automation networks using PROFIBUS technology. Time-synchronous DP-V2 communication provides precise data exchange for drive applications, while support for configurable DP-Slave operation expands deployment flexibility. Combined with low power requirements and standard VMEbus compatibility, the board offers a practical solution for modernizing and expanding existing VMEbus installations.

The VME-PROF-M Nautibus VMEbus PROFIBUS Interface Card may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

Description
Nautibus VME-PROF-M is a complete independent PROFIBUS interface for the VMEbus, allowing straightforward integration of PROFIBUS communication into a wide range of VMEbus systems regardless of the operating system in use. Built around a 32-bit processor and the PBM-ASIC, the interface handles the complete PROFIBUS Layer 1 and Layer 2 protocol according to DIN 19245. With onboard Flash EPROM, the board operates independently without loading PROFIBUS software from the host VMEbus CPU.

VME-PROF-M functions as a VMEbus A24, D16 slave and incorporates 64 KB dualport RAM, 128 KB RAM, and a 512 KB Bootblock Flash EPROM. The dualport RAM provides an efficient data interface between the VMEbus CPU and distributed PROFIBUS devices, enabling the CPU to read and write I/O data directly. Communication is provided through one galvanically isolated RS485 PROFIBUS interface supporting data rates up to 12 Mbit/s and one RS232 serial port for configuration purposes.

With PROFIBUS DP-Master Class 1 firmware, Nautibus VME-PROF-M creates a fully independent DP-Master interface suitable for both Mono-Master and Multi-Master systems. All DP-Master Class 1 functions, including bus configuration, are executed directly on the board. Configuration and diagnostic testing are performed using the supplied configuration software, while all configuration parameters are permanently stored in onboard EEPROM, allowing automatic startup after system reset.

VME-PROF-M also supports PROFIBUS DP-Slave firmware, enabling the board to operate as an independently configurable DP-Slave interface. Configuration is completed through the dualport RAM using up to 32 configuration bytes. The interface supports as many as 243 input bytes and 244 output bytes, allowing the board to match the communication requirements of different VMEbus applications or to simulate various PROFIBUS slave devices where needed.

Designed for industrial automation, Nautibus VME-PROF-M simplifies the connection of PROFIBUS I/O modules, reducing the need for expensive VMEbus I/O boards while improving installation, maintenance, and spare parts management. Time-synchronous DP-V2 communication makes the board especially suitable for drive control applications, while hardware timer control provides microsecond-level cycle precision. Operating from a +5 V supply with typical current consumption of 700 mA, the board requires no +5 V standby or ±12 V power and supports operating temperatures from 0°C to +50°C with storage temperatures from -25°C to +70°C.

Technical notes
The Nautibus VME-PROF-M interface card streamlines network deployment by storing all essential slave communication parameters directly into its onboard EEPROM. It offers independent protocol handling to offload the host VMEbus CPU, making it an ideal drop-in replacement for vintage automation networks.
