- A rerun of [hardware test]: S7-1200 CPU 1212C V4.7.3, classic S7 — pass (13/13) #907 on the same CPU, after the runner fixes in test: keep PLC and host details out of real-PLC artifacts #908.
- Smoke (read-only): 5/5. Scratch writes (
--allow-write, DB2 only): 8/8 types (INT, REAL, BYTE, WORD, DWORD, DINT, CHAR, BOOL), each restored and read back.--allow-adminoff. - Both fixes hold. The order code is recorded, and the JUnit XML carries no
hostnameand no PLC address, so nothing needed redacting this time. - One small thing: the recorded order code keeps a trailing space (
"6ES7 212-1BE40-0XB0 "). The runner strips NUL bytes and not the space. - DB2 was read whole before and after the write pass: byte-identical (all 38 bytes compared).
- The manual upload and download check from Formalize real-PLC acceptance testing with Gherkin scenarios #840 was not repeated.
Safety confirmation
- I reviewed the attachments and they contain no PLC address, credentials, private keys, plant/site identifiers, or proprietary PLC program.

Recorded in the new Tested and Verified Hardware section of the PLC support matrix (#947). Thanks for the runs!
