hello,

i used wireshark and don't see any traffic problems.
why sometimes the datachange jumps after 3 minutes ?

thank you,

hello,

another live example :


this is from logEntry :

2015-05-05 18:04:39 – m_EasyUAClientCoils_MonitoredItemChanged PlantModel 2407 Exception OpcLabs.EasyOpc.UA.Engine.UAClientEngineException: The OPC-UA subscription publishing has stopped.

2015-05-05 18:09:34 – m_EasyUAClientCoils_MonitoredItemChanged PlantModel 2406 Exception OpcLabs.EasyOpc.UA.Engine.UAClientEngineException: The OPC-UA subscription publishing has stopped.

and this is from my log :

2015-05-05 18:07:43 – m_EasyUAClientCoils_MonitoredItemChanged line 2406 state MachineMode Value 4

2015-05-05 18:07:43 – ServerTimestamp 5/5/2015 3:07:41 PM SourceTimestamp 5/5/2015 3:07:41 PM StatusCode Good


1. pay attention what happened at 18:07:43 : i get the tag dataChanges with ServerTimestamp=SourceTimestamp=5/5/2015 3:07:41 PM , but the tag coilStatus was changed in 18:04-18:05 - i saw this in live, and it takes me to get the dataChange event 2 minutes and 43 seconds and this a lot of time, and i want to reduce it to 3 seconds at max.

2. also pay attention that in 18:07:43 i get 7 dataChanges of different tags, and i am sure this 7 tags doesn't change at the same time, and it's like someting was stuck and than after 3 minutes was released.

any explanation why i am getting this delay in when using dataChange event ?

Thank you,

hello,

My service that use OPCLabs and Kepware located at the same computer.
i am using MonitoredItemChanged and it's working, but the problem is sometimes i get the event MonitoredItemChanged in my code 3 minutes (!!!) after the tag was changed in Kepware.
the Kepware tag has scan rate 100 milliseconds.
i want to get the event of the data change immediately or maximum 3 seconds after the tag was changed.
below attached the code how i am using the MonitoredItemChanged. is there any other properties i should set to easyUaClient in order to get the data change immediately ?

thank you,
Adi Damty


the code :

samplingInterval = 200;
uaDataChangeFilter = new UADataChangeFilter(UADataChangeTrigger.StatusValue);
uaMonitoringParameters = new UAMonitoringParameters(samplingInterval, uaDataChangeFilter);
state = "Coil";
m_EasyUAClient.SubscribeMonitoredItem(new EasyUAMonitoredItemArguments(state, dataPointInfo.OpcServerUrl, nodeId, uaMonitoringParameters));
