- 8B PDO config: ULINT-sized payload, no 0x1A01 diag PDO on SM3 (device rejected SM3=8 with diag assigned: 'size not allowed, min/max 0xa') - twin_layout_blob_sized(): single 64-bit mapping entry for 8B payloads - Ticker: per-byte XOR 0x5A transform in 8B mode so TwinCAT can verify every byte individually (1KB path unchanged, const-guarded) - TwinCAT automation scripts: deploy with RPC retry, LinkVariables-based whole-array relink (element links only carry 1 byte), ADS watch, diag - Docs: 8B design, verification methodology, test report
