In KepSerwer during loading coniguration I got information:
Simulation mode is enabled on device 'common2OpcModel.msarna'. In Simulation mode the memory map is based on client update rate(s). Refer to server help for more information.

The same result with:
(I have use in reading: DataSource= DADataSource.Device,
but I have problem with writing)
 
  public static void Test2()
  {
	 EasyDAClient c1 = new EasyDAClient();	 
	 EasyDAClient c2 = new EasyDAClient();
 
	 c1.Isolated = true;
	 c2.Isolated = true;	 	 
 
 
    c1.WriteItemValue(new ServerDescriptor (){ ServerClass = "Kepware.KEPServerEX.V5"}, 
	  	              new DAItemDescriptor() { BrowsePath= "/common2OpcModel/msarna/L1/Z1/ZonesCtx/IsJigScanned"},true);		                  
 
	var valB = c2.ReadItemValue(
		new ServerDescriptor (){ ServerClass = "Kepware.KEPServerEX.V5"}, 
		new DAItemDescriptor() { BrowsePath= "/common2OpcModel/msarna/L1/Z1/ZonesCtx/IsJigScanned"},
		new DAReadParameters(){ DataSource= DADataSource.Device }
	);	
 
	Console.WriteLine("val=" + valB.ToString());
 }

Hi, I have some problem:
  public static void Test2()
  {
	 EasyDAClient c1 = new EasyDAClient();	 
	 EasyDAClient c2 = new EasyDAClient();
 
	 c1.Isolated = true;
	 c2.Isolated = true;	 	 
 
 
    c1.WriteItemValue("",  "Kepware.KEPServerEX.V5", "common2OpcModel.msarna.L1.Z1.ZonesCtx.IsJigScanned", true);	
 
	var valB = c2.ReadItemValue("",  "Kepware.KEPServerEX.V5", "common2OpcModel.msarna.L1.Z1.ZonesCtx.IsJigScanned");	
	Console.WriteLine("val=" + valB.ToString());
 }


case 1:
Isolated don't set = true.
Value is read as true, but I don't see changes in opc by opcclient.


case 2:
Isolated = true
Value is read as false, and I don't see changes in opc by opcclient.

Similar situation is in livemapping.
When I set values I could not see in opc client changes.
And when I set Isolated = true my tests don' pass.

In live mapping all my tags I have marked

[DAItem(Operations = DAItemMappingOperations.ReadAndWrite)]
[DARead(DataSource = DADataSource.Device)]

It looks now like writing is not performed.

Additional information:
* Reading and writing value by opc client is working.
* All tags are read / write.
* It is kepserwer with TCPIP/Simens driver and was marked as simulation
