I would be happy to do some shop floor testing on this once it's ready. - Thanks Josh

I find that I can't read atomic array elements. e.g. with Tag type DINT[2], I can't read "Tag[0]" or "Tag[1]".

Is that expected?

Is there an expected date for string/array/udt support?

@jhenson29 I have paused development for the moment as work is pretty insane for me. I hope to get back to full speed beginning early July which would make a potential release window of mid to late July.

I apologize for the inconvenience. I will certainly update this thread when I begin adding the remaining first class functionality. If possible, I will work to get a release candidate out earlier than that. That said, pull requests are welcome and if you would like to take on the challenge to get something implemented sooner then I would appreciate the help 😄.

No need to apologize. What you’ve done so far is awesome. I have some free time this weekend. I’ll look through it, but javascript is new to me (I’m coming primarily from C#) and I normally use a .net library for EIP. I have written my own code for plain tcp sockets on both ends though so I’ll have a go at it.

Thanks man! It has been a fun project for me. Feel free to join our gitter chat if you have any questions about the code base.

I am picking up development of this functionality now. Updates to come as I make progress!

That is great news. Looking forward to support of string types!

How is string type support development going?

+5 for STRINGs! 😀

First of all, thanks for the awesome job @cmseaton42 . Just checking if the support of these types is still on the road map? Let me know if you could use some help :)

Just committed STRING and LINT support to my fork: https://github.com/SerafinTech/node-ethernet-ip (Tests still need to be written: USE WITH CAUTION!)

Can we suggest adding the changes to main repo?
