Hello,
To get data from MQTT broker, you need DrvMqttClient driver.
Could you provide links to the screenshots of the project settings and communication line log?Hi,
DB export module does not provide channel name. Adding a variable that contains channel name is not planned as it would be inefficient due to performance and disk usage. If you need a channel name, it should be requested by the channel number from a separate channel table.Hello,
It sends the current channel value. Likely, the value became smaller when the module repeats sending email according to the trigger options.Hello,
Option 1
Read data from the OPC server like there are 2 different devices. Then join data to the 3rd device using formulas.
This option is good if there are not too many devices.Option 2
Install 2 Communicators. Use the save device number and line number, but with different settings. Ignore bad values using formulas.
This option is more difficult to setup.Are the described developments implemented as extensions that can be easily enabled in Administrator?
Thank you for the screenshots.
In my opinion, an object tree to filter channels by object is very useful.Could you explain how the tool to move channel works?
P.S. Please use https://imgbb.com/ or Google Drive to publish screenshots. zupimages.net works only via VPN for me.
May be the storage DLL was not found. The details are written in ScadaWeb.log
If you change the source code by yourself, use the VS debugger to check how the code works.Hello,
We can create a project to collect data from your MQTT device. To get an offer, please email us the details, including MQTT topic to read and JSON example if used.
Hi,
Usually when controller is not available, the Communicator app sets data to undefined. If you provide screenshots of the settings and data, we could provide additional thoughts about that.
Hello,
In version 5, you should set communication channel type to Undefined.
To get values from JSON, you should use JavaScript as described here.Hi,
DB export module works with current data, historical data and events.
If you need to export the configuration database:
1. If PostgreSQL is used, export can be done by few clicks from Administrator.
2. For other databases, export tables to CSV using Administrator. Then import CSV to database by some external tools (example).
