Cannot open pre_defined file

Was bedeutet 12335 ?

An attempt to open a pre-defined KAREL file (such as CRT/KB, teach pendant, or vision windows) failed. This IO_STATUS error indicates an issue with accessing these standard system I/O channels. This could be due to resource contention or system misconfiguration.

• The specified pre-defined file or I/O channel is currently unavailable or misconfigured within the system environment.
• System resources required to open the pre-defined file (e.g., memory, handles) are insufficient.
• Another program or process is currently holding an exclusive lock on the pre-defined file.

   Verify the status and configuration of the specific pre-defined file (e.g., CRT/KB, teach pendant) in the system settings.

2. 2

3. 3

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