GROUPERR_ADDR_FIFOTABLE

Was bedeutet 42EE ?

This error indicates a problem with the memory address of the FIFO table for the group. The system is unable to locate or access the designated memory region for the FIFO table, which is essential for buffering and sequencing motion commands. This can lead to the inability to execute complex motion profiles.

• System memory corruption preventing proper allocation or access of the FIFO table for the NC group.
• Invalid pointer or memory address assigned to the FIFO table during NC task initialization due to a software anomaly.
• Out-of-memory condition on the industrial PC (IPC) controller, especially with numerous or very large NC groups.
• Operating system (OS) or TwinCAT runtime component issues affecting memory management for the NC kernel.
• Firmware bug in the IPC or related hardware causing memory addressing faults for the NC memory region.

1. 1

   1. Perform an NC reset using the TwinCAT System Manager, followed by a full controller reboot to clear any transient memory issues.

2. 2

   2. Verify the available system memory on the IPC controller via Task Manager; close unnecessary applications if memory is critical.

3. 3

   3. Check the TwinCAT System Manager logs for any memory allocation errors or warnings preceding this fault.

4. 4

   4. Reinstall the TwinCAT runtime components if the error persists across multiple reboots.

5. 5

   5. If available, run a hardware memory diagnostic tool on the IPC to check for physical memory failures.
