Hi,

My example isn’t made up: the energy exchange publishes prices for the entire next 24 hours. I already have tomorrow’s prices and am entering them into the database:
0:00-1:00 100
1:00-1:00 500
…
23:00-24:00 333

Now I’m querying the database constantly, comparing the time to the current time, but the simplest solution would be to once enter data with future times into the channel.
I wouldn’t burden the system with queries, and I’d see future data in the table.

Hi,

I have a problem with my fallback trigger.
Would you look on my ACM config:

My calculated channel:

https://ibb.co/DPZFRTTG

public bool IsPowerNotLimited()
{
    return DataRel(-100).Val > 10;
}

First command is sent: Send command with a delay. Channel 281208, but no reaction of the trigger on 281208.

Some update:

I used the same trigger with delayed command to this calculated channel.
Additionally I created another trigger for this calculated channel with two commands which control the switches. I have to test it in my environment.

Channel script looks like:

public bool IsPowerNotLimited()
{
    return DataRel(-100).Val > 10;
}

I’m a bit stuck:
I created a trigger identical to the one I use to limit power, but with a 300-second delay.
The channel with the current power is channel 108.
I linked the command to a new channel (208) of type Output with the formula:

IsPowerNotLimited() ? CmdVal : double.NaN

public double IsPowerNotLimited()
{
    var ret = DataRel(-100).Val > 10 ? 1 : 0;
    SetVal(CnlNum, ret);
    return ret;
}

If the value on channel 108 is > 10, I need to shut down the system by setting channels 802 and 803 to 1.

Do I need to create a trigger for changes to this new channel 208?

[oley]

Hi Mikhail,

I will try this.
Thanks!

My problem now is that now I become evens which looks like defined channel data event:

21/01/2026 07:07:13	PV	TANGO	TangoEventCode	Defined, 311.000		
21/01/2026 07:07:13	PV 	TANGO	TangoEventCode	Defined, 310.000		
21/01/2026 07:07:13	PV 	TANGO	TangoEventCode	Defined, 271.000		
21/01/2026 07:07:13	PV 	TANGO	TangoEventCode	Defined, 270.000		

But I create a proper description for my device event in the driver (event is simple code, but has its meaning).

I want to see the description in rapid scada event table, in column description. Is this possible?

Hi,

is there a specification of the dat file format?
How to export complete historian data to csv?
Writing an importer to existing DB with ef.core will not be a problem.

Hi Mikhail,

I tried to do this similar to DrvSimulator.

internal static class TagCode
{
    public const string TangoEventCode = nameof(TangoEventCode);
}

public static List<CnlPrototypeGroup> GetGroups()
{
    List<CnlPrototypeGroup> groups = new List<CnlPrototypeGroup>();

    CnlPrototypeGroup group = new CnlPrototypeGroup("Events");
    group.AddCnlPrototype(TagCode.TangoEventCode, "TangoEvent");
    groups.Add(group);

    return groups;
}

DeviceTag eventTag = null;

if (DeviceTags != null)
{
    eventTag = DeviceTags[TagCode.TangoEventCode];
}

DeviceEvent devEvent = eventTag != null
    ? new DeviceEvent(eventTag)
    : new DeviceEvent();

devEvent.Timestamp = eventUtcTime;
devEvent.CnlVal = code;
devEvent.CnlStat = CnlStatusID.Defined;
devEvent.Descr = descr;

DeviceData.EnqueueEvent(devEvent);

I have created a channel in Scada bound to TangoEventCode tag.
Now I become an event in web app, but this contains Defined, <code> not my description of the event.

Do I need to create a channel in Scada? If I use this driver for all my devices I have to gave this tag unique name with device number coded or similar.

I want to see my generated event with the description I created for it.

Hi Mikhail,

I take a look at RapidGate and another backup strategies.
The link to the English document does not work.
Would you provide a valid link?

[oley]

Hi Mikhail,

I tried yesterday and have success with type 3. Channel value has changed.
Unfortunately (it’s not so bad) I need 2 triggers: switch opened and switch closed.
Type 2. Channel data has changed fires every time I’m uploading configuration, and another disadvantage: I can’t define range of channels.

[oley]

Another approach that scales even better: EventTrigger.
I just set the channel and nothing else.
I connect the copied Notif command to the DrvHttpNotif device.
After changing the channel, an event appears, and in the ACM log I see:
2025-12-04 21:57:45 Send command. Device 200, command Notif
Unfortunately, nothing happens, silence in the DrvHttpNotif device log.
Any idea?

[oley]

Hi Mikhail,

I was able to get it working with ACM and the phone book – I just need to use the Notif command.
Unfortunately, if I have Channel DataChange Trigger in ACM, it fires after every configuration upload.

[oley]

Can’t find any doc for this driver. Can you give me a link to this description?

[oley]

Hi Mikhail,

thank you. I can send an SMS from SCADA with simple “Request” command. It works.
Now I want to use it as notifier. So I have some contacts in the address book.
I have Channel Data Change Trigger in ACM.
How to connect this together? Command to device DrvHttpNotif? But how to access this address book?

[oley]

I made it work.
I created a proxy service that accepts POST requests and sends SMS messages with two-factor authentication based on them.
Since the request is in JSON format, I have to use [param] instead of {param} for the parameters.
The Headers tab probably refers to the response, because when I set Content-Type there, I kept getting the error: “Error creating request: Misused header name, ‘Content-Type’. Make sure request headers are used with HttpRequestMessage, response headers with HttpResponseMessage, and content headers with HttpContent objects.”

I will send something like: {CnlName} on {EvDev} at {EvObj} changed value to {CnlVal}

I suppose this should be Channel Data Change Trigger and than Command with code “Request” to my Notifier device.
Now is the question: how to send SMS to a recipient from the address book?
