Hello,
Please provide the corresponding screenshots.

Please let me know about the result.

Hello,

In ScadaServer.log

2026-08-05 18:59:22 [ENGINEERING][ENGINEERING$][ACT] Command to channel 104 from user with ID 2
2026-08-05 18:59:22 [ENGINEERING][ENGINEERING$][ACT] Command is queued to be sent to clients

That’s good.
I guess that Communicator does not receive commands, because both the ScadaGenerator app and the ScadaComm service are logged-in as the ScadaComm user. There is a protection to avoid infinite command loop. Try using the ScadaWeb user in ScadaGenerator.

I thought about a script, which checks the current local time and stores day and month starts values in separate channels.

This is possible.

[Mikhail]

Hi,

For the second one (which grows continuously) I need a daily and monthly value.

Try ModDiffCalculator for that channels. Also Elastic Report Plugin can calculate the differences.

For now ibb.co is down. Could you upload the screenshots to another hosting?

[Mikhail]

Hi,
If you use Time/Period, Delay is not needed.
Delay is useful to slow down polling if Time and Period = 0.

[Mikhail]

Each case requires each own formula. There is not enough information to make a recommendation. If data has been collected, related screenshots can help.

[Mikhail]

Hi,
You should play with Time/Period parameters. Set them to 00:00:05/00:00:10, for example, and check communication line log.
The Delay parameter specifies a delay after each request.

Thank you.

Please describe and provide examples of the channels that act as sources.

[Mikhail]

You should check the historical archive options.
I suppose, it is possible to disable auto recoding data, so it will not be overwritten. And there is an option to pull timestamps to the period.

[Mikhail]

Hi,
Of course, for production, you should update password for the DB, and change it in ScadaInstanceConfig.xml. Note that it is encrypted there.

[Mikhail]

Hi,

By default ScadaInstanceConfig.xml contains credentials for the user/password postgres/postgres
Try using the default version of ScadaInstanceConfig.xml and set the above login and password for the database.
