Judging by the value, it’s possible that there’s an error and it’s actually 32 bits, not bytes.

The polling time of different devices will periodically coincide, but this is not so scary. Since polling on different lines is performed in different tasks.

[manjey73]

Currently, we’ve been using the default settings (zero), which means continuous polling, but I want to reduce the load and implement fixed intervals for the devices. If I set Time/Period to 00:00:00/00:00:05, will all polls start simultaneously?

Yes, as far as I remember, the survey will start at the same time, and then every 5 seconds a survey will be conducted, also at the same time if the devices are located on different lines.

If you set both the Time and the Period, then you can distribute the surveys.
For example, set the time to 5 seconds, the period is 5 seconds, then in theory this device will be polled every 5 seconds
Set the other device to 7 seconds and 5 seconds, then the device will be polled every 7 seconds.

I suppose the question is similar.

[manjey73]

As far as I remember, @Mikhail ‘s suggestion was to write in Postgre and filter at the DB level

It doesn’t seem to be treated, I also wondered about disabling (Normalization) when outputting Events.

[manjey73]

That is, in the billing channel, you will always have either status 1 or 23, for example, and there will be fewer events.

[manjey73]

Then you will most likely need settlement channels. Because otherwise you will register all statuses, not only =23. As far as I understand, events do not have filtration

[manjey73]

For example, you get a value from the Communicator that needs to be handled differently from the channel boundaries. The status in the normal state will always be =1, you use control based on other criteria and change the status to your own, respectively, adjust the status mask for displaying and controlling output to Events.

[manjey73]

Yes, you can only enable “Status changed”
and, depending on the destination, use monitoring and status change in the second part of the input formula.
Channel formula : status formula

[manjey73]

Channel data – value or status

<Option name=”EventCount” value=”100″ />

in ScadaWebConfig.xml

[manjey73]

Use an Event Mask
I can’t think of anything else.

[manjey73]

try to split the parameters into two devices, mydev1.1 and mydev1.2, and specify the second as command reading in the Communicator settings. well, and link the team.

Step 1 – Create an archive in Instances – Default – Server – Archives
Step 2 – add the created archive with the bit indication to the secondary table

WritingPeriod – The recording period starts from 1 second
