public double CheckComm(double min, double max, double mult, string str = "" )
{
if (Cmd < min || Cmd > max) throw new Exception($"The value must be within {min} - {max} {str}");
return Cmd*mult;
}

public double CheckComm1(double min, double max, string str = "" )
{
if (Cmd < min || Cmd > max) throw new Exception($"The value must be within {min} - {max} {str}");
return Cmd;
}

Commands have a mode where you can raise an exception.
I made myself two formulas for convenience.

CheckComm(16, 32, 10, "degrees")

An XML script is the result of an export from a script table. It needs to be imported, not copied as it is. XML is saved in UTF-8 format, so there should be no errors due to the operation of the site, etc.

[manjey73]

ExportTON

try to import

[manjey73]

You may have picked up extra characters. You need to make copies of windows framed with the CODE tag. For example, if you copy the code that you copied here, we get an error because the site changes some characters to others.

[manjey73]

Strangely, I copied these scripts to a new project, and there were no similar errors with saving XML.

The service channel with the Status tag works only when the Communicator starts one or another driver. When polling is turned off, this channel does not work.

Probably using the Status signal from the Communicator when the line is running. But in principle, no one prevents you from duplicating the status of the channel(s) when the server turns it into an invalid state and turns it gray (you need to see what kind of status number it becomes, but it seems to be 4)

My solution is on an additional calculation channel with a timer.
For example, we added input channel 110 to the Device with the Status tag code.

I am adding an additional channel 111 – Calculated – The input formula for the TON timer

TON(ValRel(-1), 2, Val(), "m")

TON(IN, PT, Q, “min”) – IN – The value of the controlled channel can be explicitly specified as Val(110)
PT – A unit of time, for example, if in minutes 2
The Q channel for the control output, if the formula is used by itself, it is necessary to specify the current channel Val() – these difficulties appeared when I had to make two timers in one formula, more on that later
“m” – Specifies what the units of time are s, m, h, or sec, min, hour are allowed -see the formula
The timer index can be omitted when used in the
channel, by default = 0. If you use multiple timers inside other functions, you can use multiple timers by adding indexes to them and assigning internal variables to them.

The formula in the Script table

// IEC timers and others
public static long Ticks()
{
DateTime now = DateTime.Now;
long time = now.Ticks/10000;
return time;
}

protected class UtilTimer
{
public long et;
public bool flag;
public bool q;
}

protected Dictionary<string, UtilTimer> TonTimer = new Dictionary<string, UtilTimer>();

// Timer with a delay of turning on TON
public double TON(double IN, double PT, double Q, string str = "", int idx = 0)
{
var ut = new UtilTimer() {et = 0L, flag = false, q = false};
string keys = $"{CnlNum}_{idx}"; // The key is the channel number plus the timer index, zero by default.

long ET  = 0L;
long _pt = Convert.ToInt64(PT);
bool q   = Q > 0;
bool _in = IN > 0;
string s = str.ToLower();

if (s == "s" || s == "sec") _pt = Convert.ToInt64(PT) * 1000;
if (s == "m" || s == "min") _pt = Convert.ToInt64(PT) * 60000;
if (s == "h" || s == "hour") _pt = Convert.ToInt64(PT) * 3600000;

if (!TonTimer.ContainsKey(keys))
{
    TonTimer.Add(keys, ut);
}

if (!_in)
{
    TonTimer[keys].q = false;
    TonTimer[keys].flag = false;
    TonTimer[keys].et = 0L;
}
else
{
    if (!TonTimer[keys].flag)
{
    TonTimer[keys].flag = true;
    TonTimer[keys].et = Ticks();
}
 else
 {
     if (!q) ET = Ticks() - TonTimer[keys].et;
 }
 if (ET >= _pt) q = true;
 TonTimer[keys].q = q;
}
q = TonTimer[keys].q;
return Convert.ToDouble(q);
}

// Returns the channel value relative to the current channel.
public double ValRel(int offset)
{
  return Val(CnlNum + offset);
}

And now we are setting up some other actions for the channel channel with a timer.
When using the Automatic Control Module, you can do without these formulas, but for me it is not always convenient. Moreover, I use the timer for solving other tasks.

@isabellacog What exactly is the goal?

for example, I make a calculation channel for the input channel of the Status Communicator and make a timer script to eliminate false alarms in case of short-term reading errors.

You can also check some channel for status =4, if I’m not mistaken, and also make a timer to skip false alarms. Or without a timer, if the server sets this status only after a certain time.

[manjey73]

We need to look at the logs of the Communicator and the Server, what does it say?

[manjey73]

Show the channel settings with the Status tag again

[manjey73]

21 – Input, data type – double or empty
Formula (script) none
Format – Normal-Error in table Normal; Error

[manjey73]

Status works differently, if it returns 1, it means an error. There is a Normal-Error Format for this.

[manjey73]

The formula is really weird and seems useless. What exactly do you want to do with the channel data?

[manjey73]

Just manually create an input channel in the device with the Status tag code in the database. Channel value 0 = Normal, 1 = Error

[manjey73]

There is a Status service tag for devices in the Communicator. This is probably the best solution.

[manjey73]

Use ChartPro
