The topic is old; back then, the certificates were valid for 1 year.
The point is to delete the certificates so that it doesn’t pull in the old data.

[manjey73]

Yes, I found the certificate by searching for the *.der file.
/root/.locale/share/OPC Foundation/pki — everything is there, both the certificate and the key.

In addition to the folder c:\ProgramData\OPC Foundation\pki\trusted\certs\
I also ran certmgr.msc via Run and removed it from the UA_MachineDefault branch
After that, a new certificate with a validity period of 1 year was created

Depending on the system, see the options.

You need to find the certificates, including those in the trusted list, delete them, and then restart the line.

For manual submission, set the command format to String. Use HEX and enter A5A5 or B4B4.

Look at the formula tables.
There is a standard formula for reading bits.

You can check how this is organized through the Modbus driver by specifying the Bitmask and then creating channels using the wizard.

GetBit(double val, int n) in the second line of scripts

An example in the input formula – GetBit(Val(101), 2)
Get the 2nd bit of the channel value 101

By analogy. Go to the Table, click the gear.

Find the entry ‘Min’ in one of the fields of the Graphics template and replace it with your archive code ‘Sec’

Next, create a table where you will have data only for ‘Sec’, and in the table parameters, specify the line for running the Archive.

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
