I have a Machine with LabviEw V 9.0, communicating with a Siemens S7-300 PLC, using a National OPC Server. The software works fine, but sometimes, the "error -1967345629 occurred at an unidentified location" appears and the sftware stop.
This hapenning with no reason aparent two or three times a day.
The national support sugest me to sequence all de shared variables by the error input/output. I make this, but the problem still hapens.
The error also hapens with the opc in the simulating mode, without the plc, so the problem isn't the communication between the plc and the opc.
Thanks for any help
Carlos
