Just the error is different:

Update: I removed the installation and reinstalled it without copying the old config. The “clean” installation shows the same problem.

Tried to post the screenshot again because of broken link.
Solved.
The funny thing is, previousely I tried restarting the Pi, but it didn’t help. Now I called the scadarestart and webrestart scripts, and now its working again.
there should be an screenshot in the middle of the text, here’s the link:
Any news on that topic? I’d like to plot temperature (range 0-40°C), pH (range 6.5-7.5), redox (range 600-850) an sone binary signals on one chart. I’d buy the chart pro plugin immediately, but with all signals having the same scale this doesnt make any sense for me.
Ok, now I got it. I checked the register values with ModbusPoll software, and noticed there was a combination of 2 problems: first of all, the the adress was shifted by 1, and the word-order wrong. In combination, I didn’t notice the mistake while reading the floats, because the values seemed reasonable. I just noticed, that it was wrong while trying to send floats. With the word order exchanged and shifting the adress, everything works. For receiving, I use the fRevers formula.
Thank you all!
This doesn’t work as well. Now at least I know that if I turn on formula, that I can enter a “Value”, and not only “String” or “Hex”.
But the device receives only garbage. I also tried some other formulas I found in the forum, but as the description is often Russian, I don’t understand the explainations.Receiving floats works without any problems, why is sending that complicated and requires messing around with formulas? 🙂
