Hi,

If I set this to “Channel Status Has Changed”, some event would possible get logged when the Status changes to 1 which I can later review.

Try “Channel Data Has Changed” or “Channel Status Has Changed”. Play with it.

Hello,
What Rapid SCADA version do you use?
Press F12 to open browser tools. In the Console tab there are additional info about scheme loading.

Hi,
May be you could setup generating events for those channels to control when they change.

[Mikhail]

Seems, that a good approach would be to change a communication protocol. It would be more efficient to receive bunch of data that contains many data points.

Hi,
In Chart and Chart Pro plugins, the X axis is always time, Y axis is value.

Hi,
The module writes to its own log file.
Open Administrator – Instances – Default – Server – Logs, then set the log filter to modules.

[Mikhail]

Other explanation is that I’ve written too many code in JavaScript recently, so I messed up C# and JavaScript 🙂

Hi,
In Rapid SCADA 6 the script functions must be public. Otherwise the calculation engine cannot see them.

Hi,
So the result would be something like

public double TimeToGetHigh()
{
  int hour = Timestamp.Hour; // the Timestamp is a built-in property
  return (Timestamp.Minute >= 0 && Timestamp.Minute < 6) && (hour == 8 || hour == 12 || hour == 18 || hour == 22)
    ? 1
    : 0;
}

Hi,
Try the function below (not tested):

function double TimeToGetHigh()
{
  int hour = Timestamp.Hour; // the Timestamp is a built-in property
  return Timestamp.Minute == 0 && (hour == 8 || hour == 12 || hour == 18 || hour == 22)
    ? 1
    : 0;
}

Note that UTC hour is used.
The channel input formula: TimeToGetHigh()
Channel type is calculated.

Hi,
Yes, it’s possible. Please describe the entire task, so I could suggest the better way. What do you plan to do with 0 and 1?

[Mikhail]

Alternatively, use Auto Control Module and a time trigger.

[Mikhail]

Hi,
I suggest some optimization:

1. The above script creates an array on every call. It’s better to initialize the array only once.

2. Use the TimeOfDay property instead of creating new DateTime manually, and compare time spans.

[Mikhail]

I suggest using DateTime.UtcNow.Hour instead of DateTime.Now.Hour because converting universal time to local is slow. Of cause, modern computers don’t notice it.

[Mikhail]

Third, create formulas to insert phone number into commands.
