Issue Details

  • When running my LabVIEW code, I am getting an Error 1 coming from my TCP Close function, why is this happening?

Error 1 occurred at TCP Close Connection in VI

Possible reason(s):

LabVIEW: (Hex 0x1) An input parameter is invalid. For example if the input is a path, the path might contain a character not allowed by the OS such as ? or @.

============================================

Command requires GPIB Controller to be Controller-In-Charge

Solution

Error 1 in the LabVIEW TCP Close Connection Function typically happens when the session that you are trying to close is already closed. Verify other places in your code where the section could have been closed and also make sure the Connection ID references are wired throughout the code as expected.
