For a simple get you should do the following:

 

EpicsClient client = new EpicsClient();

client.Config.ServerList.Clear();

client.Config.ServerList.Add("129.129.130.88:5064"); // replace with the broadcast address or with the server / gateway one

EpicsChannel<int[]> record = client.CreateChannel<int[]>("TOTO:INT");

int[] data = "">

for (int i = 0; i < data.Length; i++)

{

    if (i != 0)

        Console.Write(", ");

    Console.Write(i);

}

Console.WriteLine("");

 

 

For a monitor:

 

static void Main(string[] args)

{

    EpicsClient client = new EpicsClient();

    client.Config.ServerList.Clear();

    client.Config.ServerList.Add("129.129.130.88:5064"); // replace with the broadcast address or with the server / gateway one

    EpicsChannel<int[]> record = client.CreateChannel<int[]>("TOTO:INT");

    record.MonitorChanged += new EpicsDelegate<int[]>(record_MonitorChanged);

    Console.ReadKey();

}

 

static void record_MonitorChanged(EpicsChannel<int[]> sender, int[] newValue)

{

    for (int i = 0; i < newValue.Length; i++)

    {

        if (i != 0)

            Console.Write(", ");

        Console.Write(newValue[i]);

    }

    Console.WriteLine("");

}

 

Personally I never use the Get function.

Hello,

 

I’m trying the EPICS C# Library in order to create a client to manage a Camera IOC. Unfortunately, I have some problems with the monitoring of waveforms records.

 

I want to monitor a waveform PV which contains data of a 640x480 gray scale picture (integers from 0 to 255). So it’s a large waveform of 307,200 elements. When  I process the following code, I catch a “Server did not respond in Time to Get Request” exception ( or , in debug mode,  the code doesn’t return).

 

 

EpicsClient m_client = new EpicsClient();

try{

                EpicsChannel<int> m_acquisitionCamera = m_client.CreateChannel<int>(“CameraJAI :Acquisition”) ;

                Int[] l_data = m_acquisitionCamera.Get<int[]>() ; 

} catch (Exception e){

                System.Console.WriteLine(e.Message) ;

                System.Console.WriteLine(e.StackTrace) ;

}

 

Is there a way to fix this problem ? Any advices ? In order to really create a monitor, someone can show me a short sample of an EPICS C# monitor which manages an array record.
