Hello
I have a similar problem. I get the same error message (210). I tried ping in the command prompt and this seems to be OK (same respons as in the tutorial made by unitronics).
I also went to info mode, the IP addresses are all correct (uploaded via serial) but socket 1 is initialized & not connected.
In ladder I removed the socket initializer, but that did not change a thing.
I am using a SM43-J-R20.
Can anyone help me out?
Thanks in advance.
RFT
