IO64x-32: Multi-node Simulator I/O Module for Industrial Protocols

32 node simulator I/O module for PROFIBUS with Simulink driver blocks

This I/O module allows the simulation of 32 slave nodes. Options are available for PROFIBUS.

  • Real hardware interconnects running on physical bus in real-time
  • Proven protocol stacks used in millions of embedded devices
  • Full Simulink workflow integration with separate blocks for each node.

Each node has its own network controller chip with a full network stack and is controlled via dual-port memory.

Up to four of these I/O modules can be installed into a Mobile real-time target machine to provide up to 128 nodes.


This solution has several advantages when compared with a pure virtual simulator:

  • Nodes run in real-time with parallel execution
  • Each node is completely independent
  • Network collisions can happen in the same way as on a real bus
  • Component failure can be simulated by shutting down a node.


This I/O module is suitable for the simulation of large scale industrial setups including:

  • Ships and submarines
  • Process machinery
  • Train networks
  • Wind farms
  • Solar parks
  • Tidal arrays
  • Power grids

Controller Hilscher netX52 network controller chip with a full network stack and is controlled via dual-port memory.
Other A termination resistor network can be enabled using an externally accessible toggle switch.
MTBF (Mean Time Between Failure) - MTBF values shown are based on calculation according to MIL-HDBK-217F and MIL-HDBK-217F Notice 2; Environment: GB 20°C. The MTBF calculation is based on component FIT rates provided by the component suppliers. If FIT rates are not available, MIL-HDBK-217F and MIL-HDBK-217F Notice 2 formulas are used for the FIT rate calculation.
