The system, from now on referred to as HSRIO, allows the management of remote I/O from a PC via high-speed LAN connection.

By remote I/O we mean a series of intelligent units dedicated to logical and analogue input/output functions, motor control, encoder reading, etc.

The choice of the LAN type connection allows to obtain two important performances:

  • standard interface, which does not require additional hardware for connection to a PC as all are already equipped with it.
  • high data transfer speed

High Speed Remote Input Output

Example functional diagram


  • Ethernet 10/100 MHz RJ45 bus, relayed to local bus
  • High speed synchronous serial or RS485 bus 115 Kb/S
  • Very fast protocol: 0.2 ms / CPU (e.g.: 5,120 digital inputs and 2,560 digital outputs in 1 ms)
  • Up to 250 CPUs
  • Up to 16 local and remote modules per CPU (up to 128,000 digital inputs and 64,000 digital outputs in 50 ms)
  • Optical fibre connection possible
  • Wireless connection possible (in case of non-criticality)
  • Internet connection possible (in case of non-criticality)
  • Ethernet network usable by other applications (if not critical)


  • 24 Vdc power supply
  • DIN rail mounting
  • Extremely compact: 24-48 x 100 x 120 mm (w x h x d)
  • Removable screw terminal blocks and D-shell connectors (counters)
  • Economical, robust and fast wiring


  • Configuration and testing tools
  • Driver Windows® e RTX®
  • Softlogic, Motion control and SCADA hiPlc®


  • Flash memory for configuration hold
  • Configurable output Watchdog


  • multi-axis fast machines
  • packaging, palletisers
  • Cartesian robots
  • automatic warehouses
  • building automation
  • Testing
  • etc.
