Maybe you can also make the parameters of function block SHLD non-volatile (Persistent parameters).
If you restart your computer and/or download new program then it will not lose the previous stored value.
And storing the value every midnight in a database and then trigger the SETH input would give you a nice overview of the daily consumption.
Today I moved the complete project from my mobile HDD to the local network drive and started compiling + download;
This time it took 6minutes and 15 seconds without the downloading.
Then moved the complete project folder to the documents folder on my C:\ drive, again it took several minutes.
Connected my mobile HDD with the original copy of the project and tried again.... 10 seconds without downloading
Second attempt with a new copy on the network drive gave me the same result....it took minutes to compile.
... so far the testing....

@cechurat this varies a lot. Now I compiled, without any updates, within 20sec (downloading included) And with or without Webwatch doesn't make any difference. In the past, with the same project, there were times that I could easily get myself a coffee while compiling. Maybe I should restart my workstation more often? This computer remains running 24/7...
I still don't know why it is sometimes compiling very fast and other times really slow.
The same, slow, behaviour I noticed during programming as well. You double click a function block to open the properties and it takes 2, 3 seconds. It doesn't seem a lot but it is annoying and especially if you know it is not always like this.
For the moment I am at work but at home I have had the same behaviour.
20s is of course not a problem
If it happens again I'll let you guy's know, for the moment it's perfect;
@cechurat ...it's the compiling which always takes quite some time on my computer, especially when the project is getting bigger. I already excluded the WebWatch in the HMI block which is already a big timesaver if you do a lot of compiling.
@cechurat This button exists already quite some time but I never understood the purpose of it.... good to know.
Btw, what is the best way to only compile and upload the hmi-files without having to compile all the tasks?
@cechurat After uploading my initial project I did some changes to the external SVG file but this was not recognized when I did a new download. None of the hmi files were processed and thus not updated although I had made changes to an external svg file which was used in some of the hmi-pages.
I needed to make a small change in each hmi.svg-page to trigger this processing.... a small bug I guess. Is there an easy workaround?
Just did a quick test with a local connection type and it is working, so I guess the other connection types will also work.
This is a huge improvement for our project, it gives us the possibility to create a menu that is found on every single HMI-page.
And if I change something to the menu I don't need to copy this to all separate hmi-files.... super.
@apollo Btw, can this external file contain REXYGEN objects?
@cechurat Thank you, I'll give it a try....
@cechurat All working fine it seems....
By the way, thus this version already includes the external-svg feature which you mentioned in following topic : https://forum.rexygen.com/topic/193/user-menu-with-custom-html-object/3
