using within subflow, support for environment variables. #62

Hello.

I would like to use this node from within a sub-flow and pass in the PLC ip address via a environment variable. I am using ${var_name} syntax. It appears not to work, is this possible?

Thanks.

it does work. I created a new end point in the sub flow from scratch rather than copying and modifying.
