Siemens S7-1200 Tag issues in 8.0.6

I am having a similar issue can anyone help me with this.

Did you follow the instructions on this page?
Can you ping the plc from your gateway machine? Are there any errros in the logs?

I had the same thought..... However come to find out after buying the license you are limited to 1000 tags total and you have to configure a server interface which doesn't work anything like it does on S7-1500

Yeah, the S7-1200 OPC UA implementation leaves a lot to be desired. It's much more limited, and any custom structured types defined and used in a "Server Interface" model can't be read by Ignition right now because the S7-1200 doesn't support the older datatype dictionary mechanism.
