Hi everyone,
Thanks for the replies, Gives me something to chew on,
I have set up open socket communications plenty of times before from S7 1500 but usually only to printers and the like.
pretty easy process.
Just when I tried to do the same thing with a laptop instead of a printer I cant seem to establish a connection.
I tried opening the laptops ports via the ''windows firewall and advanced security'' but it didnt help.
I have a customer who wants to communicate with our system over tcp. So I want to verify I can do it with my laptop so I know it can be done before they attempt etc.
