Please provide a screenshot of the form that displayed by clicking the Register Driver button.

Hello,
> 2. Is the root page http://localhost/ available?
> Service Unavailable

If service is unavailable, IIS is not properly installed. The issue is not related to Rapid SCADA, you should fox IIS.

[Mikhail]

Hello,

Please provide the info as follows:
1. What operating system is used?
2. Is the root page http://localhost/ available?

[Mikhail]

Hello,

1. Open the Drivers page in Administrator.
2. Select the KpModbusSlave.dll and click the Properties button, then click the Register Driver button.

Also the code is written in a communication line log.

Hello,

When a new date begins, the expected behavior is that an operator should manually change the date picker. However, our customers often ask to change date automatically at midnight.

So, automatic change of current date will be included (and already implemented) in Rapid SCADA 6. It affects table views. The event panel at the bottom has no date picker and shows the specified number of recent events. To get events for the selected date, a report should be generated.

[Mikhail]

Yes. Unfortunately it disappeared after the last forum update. I will check if it’s possible to get it back.

6. Request element group “ch1.012”
7. Send (12): 05 43 00 00 00 06 01 03 04 4C 00 64
8. Receive (0 / 7):
9. Communication error!

Item 8 waits for data during the timeout, expecting 7 bytes. No data was received.
Network does not guarantee 100% packet delivery.

Hi,
In addition to the previous answer.
Color also can be taken from channel status.
Channel value 1 means that device is running.
Custom channel statuses may change led color.
So channel formula could be Cnl; (Second(DateTime.UtcNow) % 2) > 0 ? 101 : 102
where 101 and 102 your custom statuses specified in the Event types table.
And in the Scheme editor specify the Status color.

Hi,

Copied from the history https://rapidscada.net/doc/content/latest/en/version-history/communicator-drivers-history.html

KpModbus 5.1.3.1 (November 15, 2021)
- Fixed data packet format for multiple commands
  Warning: no backward compatibility for multiple commands having elements of 4 bytes or more

So it affects only multiple commands when you send more that 1 Modbus element.

> For projects that are running on 5.8.2 and 5.8.3, should I update them to 5.8.4?
In my opinion, if they work stable, you don’t need to update. New projects should be implemented on the latest Rapid SCADA.

Hi,
This mess of data can be caused by a too small timeout of the device polling. When old packet comes, the app is already sent the next request and waiting for the next reply.

Hi,
The title text is taken from the Title column the Interface table.

[Mikhail]

Hi,
OK 🙂

[Mikhail]

Hello,
You can change it in the configuration of the web application.
http://localhost/scada/plugins/Config/WebConfig.aspx

After changing don’t forget to download the new settings into your project.

[Mikhail]

Hello,
In a template you can override the text of the title component and channel numbers. Other properties are fixed.

[Mikhail]

Hi,
You can use scheme template to create many views (many records in the Interface table), and then use them as widgets in a dashboard.

> we must create its base on basic components?
You should check the source code of the basic component on GitHub https://github.com/RapidScada/scada/tree/master/ScadaWeb/ScadaScheme/PlgSchBasicComp
Use the available source code as example.
