New units are no longer manufactured by Siemens and must be sourced via the secondary market, refurbished suppliers, or repair services.

Q: What are common firmware versions and updates?

Q: What causes connection drops with >25 transport connections?

On older revisions or specific firmware/hardware combinations (such as running large data frames >1 KB across more than 25 transport connections), sporadic connection aborts (with error codes like ANZW XAXA) can occur. The user program must handle retries, or the system should be upgraded/migrated.
