Dear Krzysztof,
The formula was testing. It is a great, is working perfectly.
Thank you for your help.
I am still interested in sum formula. Could you suggest me what formula will be used to get the volume of water via water flow sensor (61 litres/minute).
Thank you advance

Dear Krzysztof,
I am a man, from VietNam. Very nice to know You on this forum.
With your help i entered GetDif(133, 135) into the column “Formula” of Input Channel-Device. Where the 133 is input source channel (The consumption energy); The 135 channel of cause is difference.
https://ibb.co/SrBGGwz
Restart a server. The server is running well. But the difference i have not got. The value (5,634.90) in the 135 is the same (5,634.90) as source value in the 133. The result is bellowing:

Where is the wrong?
Pls tell me
Thanks and best regards

Dear Mr.Mikhail,
When the following formula was wrote to “Formula” table:
“double GetDif(int srcCnl, int difCnlNum)
{ double newVal = Val(srcCnl); double curVal = Val(); SetVal(difCnlNum, newVal – curVal); SetVal(CnlNum, newVal); return newVal;
}
I restart server, server is running. That means the formula is OK, isn’t?
But when to write it to column “Formula” of “input channel-device”, i can not write longer than 01 raw. Maybe the formula is too long, isn’t?
I need this formula for my demo project, so pls let me know the fee if you can not help on this forum.
Thanks and best regards

After Uploading to server. Server stop work. Check the Stats, some wrong was here

Could you tell me WHERE WILL I HAVE TO WRITE THE FORMULA? In the column “Formula” of the “Input channel_Device”??? or in the column “Source Code” of “FORMULA” table???
Thank you again

Dear Mr.Mikhail,
I can type the formula into column “Edit Source Code” of “Formula Table”.
You can see it following:

But into column “Formula” of “Input Channel” Table i can NOT type it. What will i have to configure in “Input Channel” table of rapid Scada?
Thank You again.

Dear Mr. Mikhail.
Thank you for your fast reply.
I will use Elastic Report plugin and Chat plugin but after completely creating the project.
I am trying to use the formula that was suggested by you. But i can not type full formula on column “Formula” of the “Input Table”. No longer more 1 raw. You can see it bellowing

Dear Mr. Mikhail.
I am creating a new project “Smart ScadaFarm” on Raspberry Pi4. It is running but not unstable. Maybe all my devices are connecting to RaspberryPi4-server via Rs485-WiFi converter. Is that the cause of instability?.
Now i want that all these devices will be connected to Raspberry Pi4 via RS485-USB converter. Can they connect to Pi4? How will i configure?
Thanks and best regards

Dear Mr. Mikhail,
I want to notice that i created many projects in “Demo Project”.
https://ibb.co/CQLm2tP
The only one project that was changed password and the “secret key” Button was clicked can not upload configuration. The remain projects can upload normally.
Why, i don’t understand?
Pls help me.
Thanks and best regards

Dear Mr. Mikhail,
My Demo project was repaired but not completely. I can login to web, every thing that seems is running OK except processing a upload configuration. I can not upload configuration. I checked an Instance Status that shows: “Unable to login – Invalid username or password”, “Unable to create session”.
What is wrong with Instance Default?

Could you show me again how i have to do?
Thanks and best regards

Dear Mr.Mikhail,
My Demo project was working very very well. I can login to Web every where by Username: admin, password: 12345. That seems is unsafe so the password:12345 was changed by another but i can not upload. Returns to old password 12345, can not upload. And now i can not login to Web too. Some screenshots here:

Thanks and best regards
