E_NOTSUPPORTED

Operation Not Supported in Current Mode

Beckhoff · TwinCAT 2 Automation Interface

What does E_NOTSUPPORTED mean?

The attempted operation, specifically NewConfiguration(), OpenConfiguration(), or SaveConfiguration(), is not supported in the current TwinCAT Automation Interface operational mode. These methods are exclusively available when the Automation Interface is running in Compatibility Mode.

Common Causes

  • The selected operating mode (e.g., manual vs. automatic) does not support the requested function.
  • The device is in a configuration state preventing the execution of the current command.
  • A safety interlock is active, disabling non-essential operations.

Repair Steps & Checklist

  3. 3

    Consult the TwinCAT documentation for version-specific requirements regarding operational modes and method availability.
