File is not opened

What does 12328 mean?

An attempted file operation failed because the specified file_id does not correspond to an opened file or one of the pre-defined files (CRT/KB, teach pendant, vision windows). This IO_STATUS error indicates an attempt to perform an operation on an inactive or non-existent file context. The program will abort if the file_id is invalid.

• Attempting to perform an operation on a file that has not been explicitly opened using a KAREL file command.
• The file_id used in the operation does not reference a currently active or valid pre-defined file.
• A previous file operation might have failed, leaving the file in an un-opened state.

1. 1

   Verify that the file corresponding to file_id has been successfully opened before attempting any subsequent read/write operations.

2. 2

   Ensure the file_id refers to a valid pre-defined file (e.g., CRT, KB, teach pendant window).

3. 3

   Use the KAREL command READ file_id(cr) to clear any existing IO_STATUS error condition.
