Hi,

(Tia portal v16, comfort panel 12")

I was wondering if there is a way to change the communication path of the HMI while in runtime and maintain the change? I have used the changeconnection feature which works fine but the change is temporary. On HMI power cycle it reverts back to the original IP address assigned during download. Attached highlights what the HMI thinks after changeconnection has been executed to a different IP address. 

I was thinking of making retained variables in the HMI but doesn't seem like I can do that. On power up I could default to those values.
