Hello,

So Pls let me know how to uninstall Rapid Scada Software in Raspberry Pi?

The uninstallation instruction is in the package ZIP.
But I recommend not to uninstall Rapid SCADA, because you just need to fix file access rights. If you have issues with changing file access rights, post the related screenshots on the forum.

Line Parameters – Main Parameters, then Communication Channel group box and the Properties button.

it is waiting there for few seconds without communicating with other device which is still turned ON

What date and time on your screenshot?

[Mikhail]

Hi,

Check C:\SCADA\ScadaServer\Log\ScadaServerSvc.log for the error details.

Hello,

Use the formula:
MonthBeg() ? Val(101) : Val()

where 101 is the referenced channel.
You can find MonthBeg implementation in the Formulas table if interested.
The channel must be of the calculated real or calculated discrete type.

[Mikhail]

If you already did it, repeat.

Hello,

You should provide write access to the configuration directory and configuration file:
C:\SCADA\ScadaWeb\config\
C:\SCADA\ScadaWeb\config\WebSettings.xml

or
/opt/scada/ScadaWeb/config/
/opt/scada/ScadaWeb/config/WebSettings.xml

[Mikhail]

Duplicated.

[Mikhail]

On the screenshot the line seems working.
Also please provide a screenshot of your communication channel properties.

Hi,

Rapid SCADA does support OPC UA. You should provide the error details.

[Mikhail]

Hi,

You should select an appropriate topic to discuss this issue or create a new one. As I wrote, the cause is not related to OPC and Kepware.

[Mikhail]

Hi,

Set the type of channel 163 to “Calculated real”, and set Signal to blank.

[Mikhail]

Hi,

I would insert logging in the module you working on, and see the actual sequence.

Server calculates formulas for “calculated” channels in the main thread, while data from Communicator are coming from another thread.

You should check the code by yourself. Here is a link.

Hello,

Probably 1000 connections is too many for Mono .NET framework. As I remember, an OS has a limit of open connections. It’s possible to find a command to change this limit.
For what reason do you need so many connections?

[Mikhail]

I suggest edit configuration only from Administrator. It helps to avoid such errors.
