Hi,
We have an engine running over time that retrieves opc values (single and multi values). However it stops working after a few hours giving this error message:
OpcLabs.EasyOpc.OpcException: An OPC operation failure with error code -1073479673 (0xC0040007) occurred, originating from 'Softing.OPC.OCT.DA.1'. The inner exception contains details about the problem. ---> System.Runtime.InteropServices.COMException: The item ID is not defined in the server address space or no longer exists in the server address space.
--- End of inner exception stack trace ---

at OpcLabs.EasyOpc.DataAccess.EasyDAClient.ReadItemValue(ServerDescriptor serverDescriptor, DAItemDescriptor itemDescriptor)
at OpcLabs.EasyOpc.DataAccess.EasyDAClient.ReadItemValue(String machineName, String serverClass, String itemId, VarType dataType)
at OpcLabs.EasyOpc.DataAccess.EasyDAClient.ReadItemValue(String machineName, String serverClass, String itemId)
We have a XML -> to DA bridge from Softing OPC that seems works fine
Any ideas?
We use the OPCLABS 5.2 version.
Regards
