Untick “Formula used” checkbox for the destination channel.

[Mikhail]

Well…

Add this to the Formulas table

double MySetVal(int n)
{
  SetVal(n, Val());
  return Cnl;
}

and use in the channel 1: MySetVal(2)
Channel 2 must be of Calculated real type

I already finish this work.

Great!

How are differences between Personal and Business.

Personal licenses only for hobby. In other cases, you should select licenses of the Business type. To make an order, please follow this link.

What behavior do you expect?

What exactly do I need to do for a basic mathematical function? For example: Add the value of modbus channel 1 to the value of modbus channel 2 and display it in the table.

1. Create an input channel #3 that has Calculated real type.
2. Set a formula for channel #3: Val(1) + Val(2)
3. Specify channel #3 in a scheme or table view.
That’s it.

Try SetVal(2, Val()) instead of SetVal(2, Cnl)

Hi,
I need more info. Could you provide the screenshots of the settings and the steps how you test and what you actually get?

[Mikhail]

Hi,
Please provide the screenshots of the settings you already did.

[Mikhail]

Good 🙂

[Mikhail]

I can answer particular questions about the code. If you ask more specific, I’ll try to explain.

but i suppose i need to define KPNum in SrezTableLight.CnlData at: public struct CnlData, something like: Public KPNum(double val);

I don’t recommend changing the essential classes.

[Mikhail]

Could you provide a screenshot and a part of ScadaWeb.log containing the error?

[Mikhail]

OK )

[Mikhail]

To catch that the button or toggle is clicked you need an output channel.

[Mikhail]

Hi,

You need to create extra input channels:
1st to save the previous value. Use SetData function in the formulas of the source channel for this purpose.
2nd to calculate the difference.

Hi,

The file is not available.
Press “+0” button in Table Editor.
