P6004¶

Code: P6004
Message: Unable to read file

This error occurs when the compiler is unable to read a source file from disk.

Example¶

This error typically occurs when:

The specified file does not exist
You don’t have permission to read the file
The file is locked by another process
There are hardware or filesystem issues

# Examples that would cause this error:
ironplcc check nonexistent_file.st             # File doesn't exist
ironplcc check /root/private_file.st           # Permission denied
ironplcc check locked_file.st                  # File locked by another process

To fix this error, ensure that:

The file exists at the specified path
You have read permissions for the file
The file is not locked by another application
The filesystem and storage device are functioning correctly

(* Example of a valid file that can be read *)
FUNCTION_BLOCK ReadableFile
VAR_INPUT
    InputSignal : BOOL;
END_VAR
VAR_OUTPUT
    OutputSignal : BOOL;
END_VAR

OutputSignal := InputSignal;
