SI CU: Control Unit software incompatible

What does 230672 mean?

The existing Control Unit software does not support the safe drive-based motion monitoring function, leading to a STOP A that cannot be acknowledged. The fault value (r0949) is typically for internal Siemens troubleshooting. This indicates a fundamental incompatibility between the CU's software version and the attempted safety function.

Additional Steps

Steps 1–2 are listed in Priority Fix.
