Hi,
Automatic Control Module is useful when you need to send commands according to conditions.
First, connect the equipment and try sending commands manually. After you make it work, use ACM.

In Visual Studio 2022 Community when create a new project.

You should try the setup the ScadaComm6 service to work as the OPCSrv user. See this.
It’s enough to restart Communicator that works as a service or application.

Hi,
If you didn’t change the port during installation, use the method described above.

I could not understand how to try the B Format as there is no option for B.

In the Formats table add a new format. I’m not sure that B will work, however, it worth to try.

[Mikhail]

I didn’t know there was a binary display format

It was added in .NET8. I’ve never tried it before.

Chart Pro falls on the string variable – a white screen

It cannot display graph of a string.

2024-07-29 13:30:53 [OPC-WINCC][OPCSrv][ACT] Data source ScadaServer: Connection state is Logged In

Looks like the ScadaComm6 service is not stopped. Users OPC-WINCC$ and OPCSrv are mixed in the log file.

You need to create your own module that performs auth. The links below can help.

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);
}

[Mikhail]

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);
}
