One instance of Rapid SCADA supports max. 65535 input channels. If you need more channels, deploy more instances of Rapid SCADA.

The devices can be polled in parallel. You should play with sequential and parallel polling to achieve required performance.

Tested interval of storing data into the archive is 30 seconds. You can set saving interval to 1 second, but it requires additional testing.

Are you sure that your network equipment can provide the required data flow.

Hi,
Strange, but I can’t reproduce. I send command from Communicator using my gmail. Can you send me the text of the command that caused the error?
Example:
myemail@gmail.com;Test;100°C

ExportDB module executes SQL when it receives new data from a controller. To do your task, you should create other more complex SQL scripts.

[Mikhail]

Could it be only 1 MB?
…and then it writes it (backs it up to) ..\ScadaWeb.log.bak?
..then it creates a new ScadaWeb.log file.
That is what I am seeing so far.

Yes, 1MB for the web app.
When *.log exceeds max size, it is renamed to *.bak and new *.log created.

I’m just trying to track who is logging in and out over time to the SCADA web app.

It’s possible to develop a plugin that stores all logins/logouts into a database, Rapid SCADA events or other text files.

See http://forum.rapidscada.org/?topic=administrator-does-not-run
Probably, you changed references to MSSQL Compact when build the source code.

[Mikhail]

Depends on the task. What task are you solving?

[Mikhail]

If Arduino is programmed to support Modbus, you can connect it to Rapid SCADA. See http://doc.rapidscada.net/content/en/use-cases/modbus-protocol.html

[Mikhail]

The web application writes to ScadaWeb.log
When a log file exceeds more than a fixed size (as I remember 10MB), it starts from the beginning.
Log size is a constant in the source code, there is no parameter to change.
Location is related to an application directory.

[Mikhail]

Administrator: install MS SQL Compact from the Prerequisites folder.
Webstation: use the link http://localhost/scada to open the web app.
Please create different topics for different issues.

MQTT driver is free. Rapid Gate registration described here http://doc.rapidscada.net/content/en/modules/mod-rapid-gate.html

[Mikhail]

This is generic. This approach may be included in Rapid SCADA for different tasks

[Mikhail]

I can help you with Rapid SCADA. I am not a master of Arduino. I heard there are existing implementations of Modbus for Arduino.

[Mikhail]

Add new device of Telegram type like written in the manual. Then open device properties in Communicator

[Mikhail]

You can’t send function codes manually. You should configure Modbus template that uses the function codes you need.

[Mikhail]

Function codes are predefined by Modbus standard. Why do you need your own function code? What is the register map of your device?
