The Loadable Firmware DeviceNet V4 and v5 is released.

Both Firmware variants are developed newly from scratch and are based on the same DeviceNet core component. They feature a very similar API.

Therefore, the migration from a DNS V4 based application (netX 51/52) to a DNS V5 based application (netx 90) requires less effort.

Key Features

  • Full cyclic data exchange supported (Poll, Change of State, Cyclic, Bitstrobe)
  • Diagnostic
    • Common and extended diagnostic via dual port memory
    • Stack diagnosis via packet API
  • Configuration
    • Packet API based configuration ny host application
    • Data base configuration by configuration tool (only netX 90 use case C with external flash memory)
  • Acyclic service supported
  • Fragmentation supported
  • Module Network Status Objects
  • Multiple assembly support
  • Baudrate and node-ID over network configuration supported
  • Rotary switch support
  • Attribute change indication support
  • Semiconductor device profile supportable by host application
