800B PDO variant + long-term stability evidence + analysis docs
- twin_layout_blob_sized generalized: multi-entry TwinCAT line format
(1 real @240bit + N continuation + remainder entry); 1024B path kept
byte-identical; 800B = 27 entries verified on hardware
- 800B constants (PAYLOAD/SM 800), deployed as el6695_rt_800b
- 10-min + 5h stability runs: 18M cycles, zero errors, zero mismatches,
PLC nMismatch frozen over the whole run (monitor_5h.csv evidence)
- docs: 800B plan/design/verification/test-report chapters,
jitter analysis (NFS rootfs stall primary cause), D2000 dev plan
- scripts: 800B deploy/relink/verify, mismatch-delta, 5h monitor
