Thank you for your help, now it works. I had to try several times, mervis IDE told me that the controller application failed to start. After a while I found the option "Create boot project", that was probably the missing link. Do I have to cold start the controller now every time I change something in my application or my IDE in order to have the working login function?
Further imho the login this way is not a really nice solution, because the whole HMI shown without values and it seems as the web application does not work well. A separate login screen would look much better.

Hi folks,

I'm trying to set up some security for my HMI, as I want to access it from WAN side. Unfortunately, when I follow the tutorial on youtube, setting Web User and Web Password has no effect on my HMI. I tried to re-upload my whole project, tried cold and warm restarts, nothing helps. Is there an option I overread?
I found an thread, more than a year old, where they mentioned that the login function was buggy. Is it maybe until now?

@tomas_hora Unfortunately that did not work for me because I do not use TIME variables, but TIME_OF_DAY. When I try to connect these two types, the compiler throws an error. I found a workaround to convert to TIME_OF_DAY with add_tod_time. This method means a lot of work to program the Function and HMI and it becomes slightly confusing...

Hi everybody,
I have a similar problem. I'm using some TOD-variables to schedule some things. Now I wanted to integrate them in HMI, I tried the approach below. However, I found no possibility to convert TIME to TOD. Can you maybe give a hint?
