Open-source Ethernet/IP stack
This is not new (been out since August), but I thought I would mention it as an eye opener.
Ethernet/IP, the industrial communications protocol that enables communication between machine I/O information systems, factory floor devices and enterprise systems has an open-source software stack. The stack was created and recently released by the Vienna University of Technology’s Automation and Control Institute and written in the C Programming language.
This is great from the standpoint of reducing development costs and cutting the risk of implementation. It may very well be a catalyst for vendor adoption and implementation of (the already popular) Ethernet/IP protocol. I’ll go as far as to say that it may also increase custom development from independent outfits/ system intergrators and internally within the larger industries.
