This is normal, since you moved the current data folders to tempfs according to the installation, but if you exclude this data from tempfs, then you will kill the flash card very quickly. There are two solutions, find a virtual disk for Linux, which will dump everything to disk before the reboot command. Or upgrade the formula I once made for writing variables to the retain file.
Well, you just need to add +8 hours to display in another Scada. The Scada variable itself is stored in double format and it is more convenient to already have a DateTime structure in it
You can see how to add the clock directly to UTC time, it seems that everything is in seconds there. And add this addition to the formula above and only then convert to DateTime or store real UTC time in one cell and already perform conversions and show it in the pre-calculation one.
double dtFromUtc(double utcTime)
{
var epoch = new DateTime(1970, 1, 1, 0, 0, 0, DateTimeKind.Utc);
return epoch.AddSeconds(utcTime).ToOADate();
}Add to the Reference List of formulas that are not there. And in the input channel, use this formula with the Date, Time or Date and Time
I don’t know if I understood correctly what you need
There are some problems with access rights. Configuration files are written from the system user, and you open the Web from a regular user
It is clear, so I had another reason for the Illegal data error error, since it crawled out when writing the float parameter in 5.8.3, I had to throw the library from 5.8.2 to make the command work.
Moreover, stopping the operation of the control module from the WEB should be performed only in part of the required KP, for example, during technological inspections of equipment.
But as mentioned above, the page loading will be long, it is still better to make copies of the elements and change the channels. A bit not for such things inserting a schema into another schema
Installation of Webstation Plugins
7. Download data from the server
Overload the server and also make the Ctrl+F5 command in the browser to update.
After you have entered the registration key, you need to download the data from the server, and then upload it back to the server.This should be described in the documentation.
