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

Hilscher internal information: Release Package NXLFW-DNS V4.1, V5.1

Public Information:  DeviceNet Slave - V4 and DeviceNet Slave - V5

The release of EtherCAT Slave Firmware V5.3 is significantly delayed.
New product release is planned for end of July 2021.

New features in ECS V5.3

  • SoE (Servodrive-Profile over EtherCAT)
  • AoE (ADS over EtherCAT - ETG 1020)
  • VoE (vendor-specific protocol over EtherCAT)
  • DC sync timestamp over DPM
  • configure the Mailbox StartOffsets via Set Configuration Reques

A pre-relase firmware, wich includes SoE, is available on request. However AoE, VoE are not supported by the pre-release firmware.

The delay is not caused by priority shifting, but by unexpected, unplanned additional development efforts. Thus an improved, earlier release date is not achievable.
