Connecting to Siemens S7 1500 OPC UA Server

[Frants1987]

Hello all,
Because it took me 2 days and some nerves, I like to tell you how I connected successfully to a Siemens S7 1500 OPC UA Server.

1. In the client you have to set the timeout and watchdog timeout to at least 5 seconds. I set it to 10 seconds.
2. Also the node IDs in the siemens world have additional double quote (") characters around them. So if you call get_node the identifier looks like that: "DB_Lifebit"."Lifebit"

I hope this helps someone.
Regards
Fabian
