Modbus TCP question - reading parameters in batches

Tori — Tue, 11 Aug 2026 20:28:26 GMT

Hello everyone. When I use the Modbus TCP driver, I'm reading several parameters (one after the other), and the system prompts for each one. How can I (maybe check a box) make the request batch-readable?

How to display events in the event log?

Ghaith Ali — Mon, 03 Aug 2026 06:40:00 GMT

Sorry, but can anyone tell me how to set up the event log? It's just not showing anything at all, and I haven't really figured it out yet. I need an alert to trigger when my temperature value goes beyond predefined maximum and minimum limits. I've already created an alert that evaluates to true in this case, but nothing happens.

Table Row Selection Bug

kira — Tue, 28 Jul 2026 22:01:23 GMT

Developers, take note.
I believe table row selection isn't working correctly. Currently, clicking while holding down the Shift key selects all table rows. The expected behavior is to select a contiguous range from the last selected row to the row the user clicks.

Retrieving large volumes of events

George P — Wed, 22 Jul 2026 11:17:20 GMT

Hi everyone!
Has anyone worked with a large volume of events? For example, the task is to split events into pages of 50 and retrieve them by page number. But for this kind of pagination via queries, you still have to use the event history function, which essentially needs to first retrieve all the events and then iterate through them with a query. Or am I missing something?

App architecture

Tobias — Thu, 16 Jul 2026 23:06:10 GMT

Is it correct to use dashboards with data for engineers on the same server where all the main logic runs (models, scripts, alarms), or is it better to have a separate server for dashboards that will receive data from the main server via distributed architecture?

If an alert triggered by event does not have a deactivation expression specified, will it be deactivated immediately?

Could you please tell me how to set DCAwareRoundRobinPolicy for Cassandra?

Could you tell me where the Cassandra driver is located?

User Sessions

Is it possible to separate sessions for a single user so that if a project is open in different browser tabs or windows, the session variables are generated independently within those tabs or windows?

filter() function does not return an altered table

kira — Mon, 01 Jun 2026 18:04:58 GMT

I don't know if it's a bug or a feature...

Should the filter function return a new table or not?

I've encountered a problem where after applying dr(0) to the filter function's result, it returns the first row of the original table, not the first row after the function.

I think it's a bug.

Querry error

Manya — Sun, 31 May 2026 20:32:45 GMT

Hi everyone! The LIMIT parameter isn't working in the function query. A query like this:

SELECT *

FROM utilities:variableHistory("users.username.models.modelname", "dataTableVariable")
LIMIT ?

results in the error:

Query syntax is not valid: Encountered " "?" "? "" at line 3, column 7. Was expecting one of: ... ...

Is there a way around this?
