Hello,
It’s what I’ve did for the monitor and it doesn’t seem to work. With this context I’ve tested the monitoring of a string waveform record which has a length 2 elements and all seems ok. I think that
the problem is caused by the length of my waveform record which is 307,200
Cheers,

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.
