Using Kepware Kepserver, siemens S7 plc and Labview 6i. Lots of slowdown when using multiple datasocket writes in same while loop.
Has anyone had any experience of using the above equipment to get a sensible write time to the OPC server. If I just use one datasocket write VI in a while loop I get a sensible update time to the PLC. If I add a second, I start to get update times of 2-3 seconds, and if I add a third, update time can exceed 5 seconds. The Kepware quick client has no problems updating at 100ms intervals, but it seems Labview is not communicating the data to the OPC server and this is where the delay is. Does anyone have any thoughts or experience?
Cheers
