Hello,
This is not a bug, but may be a subject for improvement. Thanks.

[Mikhail]

Hello,
How can I reproduce this error?
Could you send the error details from ScadaWebBeta\log\ScadaWeb.log ?

[Mikhail]

MatrikonOPC is optional depending on your needs.

[Mikhail]

Add Dynamic text element. Then set background color, border, alignment, etc. To setup the button behavior, specify Action and Input channel (Output channel) properies.

[Mikhail]

CmdVal works if you use it within a formula of output channel. The formula fires when you send a command related to the output channel.

Hi,

Please create a new topic, because this topic is not matched to your question. Specify your Windows version and browser.

I came across similar situation:
a device uses Modbus, but the device provides events. I can receive binary data of those events. So I had to implement a separate driver to process received events and store them.

[Mikhail]

Hi,
The current version of Modbus driver can not send custom (non standard) commands.
Imagine it is implemented. What format of the response will be received? How to decode the response and process it?

[Mikhail]

Thank you for the info ))
Did you use the formula with CmdVal in OUTPUT channel?
How do you set a new value from UI?

Is is possible to write variables to log.
Add formula:

void WriteToLog(string s)
{
  using (System.IO.StreamWriter writer = 
    new System.IO.StreamWriter(@"C:\SCADA\mylog.log", true, Encoding.UTF8))
  {
    writer.WriteLine(s);
  }
}

Then you can use WriteToLog(hour.ToString()) within other formulas.

[Mikhail]

I created another input channel to display the CmdVal of the output channel which uses SetHour().

What is the number of that channel on the screenshots?
How do you expect to behave for input channels 61, 62? Are they received from your device?

[Mikhail]

Please describe how do you send command to set hour?

[Mikhail]

I recommend to create input channels to show current values of hour and minute variables in order to control them.

[Mikhail]

Apparently the calculated channel data never appears correctly in the Scada Comm device data which I was using to check the data changes. It only appears in Scada Web.

Definitely 🙂

Now how can I send the hour and minute parameters from the output channel to my flag channel ?

Add the variables into Formulas table:

int hour = 0;
int minute = 0;

Add the code into Formulas table:

double SetHour()
{
  hour = (int)CmdVal;
  return double.NaN;
}

Use the above formula for an output channel.
Note: I don’t test code which I write in this forum. It’s just a direction for experiments.

[Mikhail]

It’s strange. Did you pass the changes to Server and restart Server service?
Try simplifying the formula of an input channel.
First of all, try the formula: 1
Then try: DateTime.Now.Minute
