In the course of continuous development, many components of the EtherNet/IP firmware were updated to latest versions and several new features were implemented.
The Firmware is intended for certification test CT18


Major Improvements

  • Extended API to fully support CIP Safety applications
  • Null Forward Open Support
    enhances usability of Rockwell PLCs
  • Single port firmware variant (standard MAC) (only V5.3, not V3.7)
  • LLDP and SNMP support (enables future CT19 conformity)




The EIS V5.3 firmware can be used on the following target devices

  • cifX M.2 card
  • netRAPID 90
  • Chip: netx 90


EIS V3.7 is available for netX 51, netx 52, netX 100, netX 500 based products.

Notes on CIP Security


In parallel to the standard firmware, our development team is working on a security enabled variant of EtherNet/IP LFW,

adding the CIP Security feature and other security related functions to EIS V5.3 for netX 90 (not for EIS V3.7)

This variant will become available as a “prototype” firmware within the next 2 month.
I.e. it will be offered to interested customers for tests and development purposes only and not yet for series production.

Please contact me in case of customer enquiries.

Further information will follow in time.
