The above post is not related to the topic. Please search for existing topics about Modbus. Probably, it’s already solved.

Also hexadecimal format would be useful.

[Mikhail]

In version 6 you can try creating a format to display value in binary form. Format code would be B

[Mikhail]

Or

public double GetBits(double val, int n, int len)
{
    ulong ulVal = (ulong)val;
    return (ulVal >> n) & (ulong)((1 << len) - 1);
}

public CnlData GetBits(CnlData cnlData, int n, int len)
{
    return NewData(GetBits(cnlData.Val, n, len), cnlData.Stat);
}

Hi,

public double GetBits(double val, int start, int end)
{
    UInt64 uintVal = (UInt64)val;
    int bitCnt = end - start + 1;
    int maskShift = 64 - bitCnt;
    return (uintVal >> start) & ((0xFFFFFFFFFFFFFFFF << maskShift) >> maskShift);
}

Communicator works as a service with the system account, while most of OPC clients work as an application.
Try the following:
1. Stop the ScadaComm6 service.
2. Open command line and execute ScadaCommWkr.exe
What will you get in ScadaComm.log and communication line log?

[Mikhail]

Thank you for the solution.

[Mikhail]

Can you compare the received data (unspecified) with data collected by any other OPC client? For example, Prosys OPC UA Browser.

[Mikhail]

The above is ScadaComm.log
But we need lineXXX.log

[Mikhail]

Option 1
Use enumeration format, for example, On-Off. The command sending form will show several buttons.

Option 2
Put several buttons on a scheme (mimic diagram). In this case you need a channel of the output type for each button, because a button component sends value = 0.

[Mikhail]

Hello,
Could copy a part of communication line log?

[Mikhail]

Do you need many buttons that send different command values via the same channel?

[Mikhail]

Creating a driver seems like the best option. Check this article.
Otherwise, you could write data to a database, then read by Rapid SCADA.

[Mikhail]

1. Open IIS management console. Type IIS in Windows search bar.
2. Select the Scada website.
3. Press the Restart button.

[Mikhail]

Hi,
You could configure Automatic Control Module to send message when channel status is 0, for example. Check this video.
