Hello,
What culture name is set in the Administrator application?
Changing language affects user interface. Logs remain in English.Hello,
Please check the license terms here.> This machine code should be generated for the Linux server, correct?
Yes. Try trial keys before purchase.> How is it done on a file like this one for ex. ?
Open the file in Notepad, add a new line and save. The driver should read new data.> What data is read repeatedly for TagA in Demo mode ?
Data from the CSV file is read cyclically according the timestamps. If DemoPeriod=OneHour, you should fill the file for the entire hour.Demo mode always use the same data. Therefore, you need Real time mode. Seconds don’t need to match exactly. Data considered up to date for 1 minute.
Try DrvHttpNotif driver. It can send any HTTP request. Search the forum for configuration examples.
Automatic Control Module is needed to send SMS automatically according to conditions.
Hi Dave,
It’s possible to delete an archive file. Look for
SCADA\Archive\Min and
SCADA\Archive\Hour folders.
There are subfolders for each date.The better solution would be developing of the utility application that allows to export data to CSV, edit data, and upload back to archive. I hope we will create such app in the future.
When you use channels of string type, despite the archive type like *.dat, InfluxDB or PostgreSQL, channel data are stored as doubles. To get the string from double, it should be decoded.
I can help you to create and debug the formula, but I will not do it by myself.You should add DrvOpcUa.Logic.xml into the Rapid SCADA project, edit the file as needed, and upload the project for execution.
What parameter in DrvOpcUa.*.xml should be updated to fix the connection issue?Hi,
In Demo mode the driver reads data from the CSV file repeatedly. In Real time mode the driver reads the last record having the current timestamp. Which mode is needed in your case?
You need to continue the CSV file to make it work. Data depend on the mode.
The idea of the formula is below.
String are encoded in Unicode, split into byte arrays and save into channels that have Double data type.
In a formula you need to convert Doubles back into strings. Then join, and convert from string to double.
If a channel has length > 1, the Server internally creates several channels with sequent numbers, so you can access their data as usual.
In the Script table, find the [5] Strings functions. They will be useful for your purpose.The other possible approach we use in DrvOpcClassic.
A user can download the structure of the OPC tags to an XML file using a utility. Then open that XML file by a driver UI instead of connecting to an OPC server. May be this approach is straightforward and easy for understanding.For example, a customer can send you an XML file containing OPC nodes. Then an engineer can use it in his office.
OK, let’s continue in this thread.
