How to write value and appear on the screen?

[enviromixti]

I need help in creating a script in which when selecting a DynamicPicture an OutPut that appears a field to enter value and changes the image from “Not selected” = 0 to “Resolved” = n and shows the value n in the Input that is DynamicText, with the condition of all days being 0 until selecting the button for “Resolved”

Hello,
To allow a user setting a channel value, create a channel of the Calculated/Output type, and set it’s output formula to SetData()
DynamicText will show the current value of the channel.

Hello,

Could you give an example of how to use SetData(), I had never used this function

Number 46804 = channel Input

Number 46805 = channel Calculated/Output Output Formula SetData(46804, …)

To write and save in internal memory and display?

[Mikhail]

Hello,
Channel 46804 is not needed.
In the channel 46805 the output formula is just SetData()
The above should work, see https://ibb.co/KqvK15r

Hello Mikhail,

Is there a formula like SetData() that can be used for text (string)?

I need to create dynamic text so that the operator can edit the text whenever necessary.

I’m using V6.

Thanks for the help.
Best regards.

Hello,

Try

public byte[] SetUnicode()
{
  if (ArrIdx == 0)
  {
    string s = CmdData == null ? "null" : Encoding.UTF8.GetString(CmdData);
    int dataSize = Channel.DataLen ?? 1;

    for (int i = 0; i < dataSize; i++)
    {
      string part = Substring(s, i * 4, 4);
      SetData(CnlNum + i, EncodeUnicode(part), 1);
    }
  }

  return CmdData;
}

Channel should be of the Calculated/output type

Hello Mikhail,

Thanks for the quick response.

I have no experience using Rapid Scada, I need a more detailed explanation.

Where should I post the code you wrote?

How should I configure the other channel parameters (e.g. Data Type, Input and output formula, format, command format)?

Thank you very much for your help and patience.

[Mikhail]

Hello,
You should add the SetUnicode function into the Scripts table. Then use it in the channel’s formula field.
If you provide screenshots of your settings, I can check.

[Mikhail]

Data type = Unicode string
Format = String
Output formula = SetUnicode()

Hello Mikhail,

I want to start by thanking you for your help.

I have already tested and your code is working.

But I need an improvement.

The result only displays up to 4 characters.

For example, if I type “asdfghjkl”, the result displayed is “asdf”.

To make sure the customer has no limitations, can you please provide a code that accepts 50 characters?

Thank you very much for your help.
Best regards.

Hi,
Try setting channel’s Data Length to 3, for example. Note that next 2 channels may not sequential channel numbers.
Each 1 of data length may contain up to 4 Unicode characters.

[XptoPT]

Hello Mikhail,

Changing the Data Length worked.

“Note that the next 2 channels may not be sequential channel numbers.”

I didn’t quite understand this note, please explain it to me in more detail.

Thank you very much for your help.
Best regards.

Hello,
If channel 101 has length = 3, there are shadow channels 102 and 103 are created by Server.
You should not use channel numbers 102 and 103 explicitly in the Channels table.

Hello Mikhail,

Thanks for the explanation, now I understand.

Best regards.
