if we can solve problem with formulas and events there is plan to test on some real project where SCADA would be accessible from outside our LAN and we would monitor location in some other company
Nice. I’m sure that all the mentioned issues can be solved. And I’ll help.
About performance:
Please wait a bit when we upload the driver update. The update will provide more details about received topics in the log.
Then we should compare the driver with another MQTT client that is installed on the same machine as Communicator and subscribes the same set of topics.About the formulas:
You should change channel type to “Real”. In this case, formulas are calculated when new value is coming from a controller or MQTT broker.Hi,
Could you provide links to the screenshots? Screenshots are more clear than text descriptions, so we could find the solution faster.
Note: the MQTT driver update is coming soon. The driver will support generating of input channels according to the configuration, and JSON parsing will be improved.
As you can see on my images I have two formulas
I don’t see any images that contains formulas. If you add them, I will check.
Value is all the time the same as in communicator
As wrote above, the result of formulas can be displayed by views, not in Communicator.
I also noticed that Rapid SCADA takes quite some time to read data from Mqtt broker. When around 80 variables is published to Rapid SCADA it takes more then 1 minute to show all the data.
Could you provide more info about that?
If we choose Rapid SCADA for our projects can we count on official support or is Mqtt community developed and so unofficial?
We also support the existing MQTT driver.
Hi,
I recommend to update the file structure on disk as you need to show in the tree
Root SiteA NewFile.schIn the title column just enter simple titles.
You can also set Title = Root\SiteA\Option1 but it’s not clear when not reflects file structure.
Is it possible to use formulas for input channels that are using MQTT?
Formulas are processed on the Server application level and they do not depend on a driver.
The result of formulas can be displayed by views, not in Communicator.Hello,
That’s mean i can not configure the device that can send email to group_name.7
It duplicates another topic.
Hello,
Please try the updated version of the driver.
In case of similar error, it can write more info in the log that helps to find the cause.Hi,
DB export module executes only 1 request per operation. If you need to execute many requests, wrap them by stored procedure on the DB side.
