Labview and CIP communication

[Lakshmi_Chithamabaran]

I have an electronic which is on TCP/IP over CIP.

I need a sample program for this.

I have developed few but that doesnt seem to work.

I have tried seeing the data trafic in wire shark.

I can see that hand shake is happening.

But i have error:

The network connection was refused by the server.

You mean probably CIP over TCP/IP, which is basically Ethernet/IP.

There are no trivial (and free) solutions for this. The Ethernet/IP Toolkit from NI is an option. Possibly the Turck Ethernet/IP Toolkit might work too. It's advantage is that it does only use native LabVIEW TCP/IP functions but it is specifically designed for Turck devices and needs some tinkering with others.

If you want to try not paying money you could also try this.

I've previously had good luck with EEIP.DLL, a .NET Framework DLL, in LabVIEW.

The site that maintained it was http://www.eeip-library.de/ but it appears to have not been renewed.  If you look a year back in the archive.org wayback machine you can still see the site.

There are still official-ish places to get it:
