Hi,
Probably, you can read the most recent event from the fixed Modbus address. Then you will get it as channel values. How will you process those channel values?

Hi,
Could you copy the packets from the communication line log as text?
They can be found in a text file in the logs directory.

[Mikhail]

Hi,
You need to upgrade to Rapid SCADA 6 to use that feature.

[Mikhail]

Hi,
Please copy a part of the communication line log to check data packets, and provide screenshots of the Modbus template.

Hi,
I sent a response on July 08. Is it put in the spam folder?

[Mikhail]

Thank you for noticing the bug.

[Mikhail]

ModDiffCalculator is discussed here. It’s free and useful.

Everything look fine except Auto Report Module automatically export the Event Report even I didn’t activate it.

It’s a bug. Will be fixed in the next version.

Everything look fine except Auto Report Module automatically export the Event Report even I didn’t activate it.

Restart the service after changing the configuration.

Hi,

After I change culture to en-GB, no errors at log and excel file (Historical Data Report & Elastic Report) when I opened them.

The PlgElasticReport.zh-Hans.xml file includes a line
<Phrase key="WorksheetName">工作表{0}</Phrase>
Likely there is some forbidden character.
Try replacing that line by the similar line from PlgElasticReport.en-GB.xml

In case of Modbus coils
Cmd > 0 ? 0 : 1

[Mikhail]

Hi,
In the output formula of the channel, put something like
Cmd > 0 ? 0xFF : 0x00
If it doesn’t work, make screenshots.

[Mikhail]

Hello,
To do that, add a new function in the Scripts table, and then use it in a channel.

public void MyFunc()
{
  SetData(501, Val(500), 1);
  SetData(502, Val(501)-Val(500));
}

[Mikhail]

can you link me with some example projects backup? I will try to restore the project and learn from there.

The Hello World project is in C:\Program Files\SCADA\ProjectSamples\HelloWorld
Other projects are owned by the customers.
There is a YouTube video about connecting devices by Modbus. It should not be hard.

[Mikhail]

Hello,

I have tried to make channels which aren’t linked to any device/communication lines

I suggest to add a device in the Devices table that has no a real device under it. It is useful for grouping channels.

SetData(417,Cmd,1)

If that output formula is used in the channel 417 itself, it can be simplified to SetData()
