Hi Mustafa
I haven't spent any time on that project so there are no changes. You could probably look at the projects I listed above and perhaps see the problem, it must either be libnodave or Advanced HMI. You can try libnodave and make sure that it works and then see the link between the two.
I don't have any experience with the 300 range, but I would expect it to be isotcp, the same as with the 1200.
