- DC selection must use the structured <Dc><Data AssignActivate/> XSD element; legacy DcData hex writes get normalized to zeros by TwinCAT - TwinCAT converts it to DcData '2003...' (0x0320) on save: SYNC0/SYNC1 cyclic + SYNC0 activate for the bridge - Verified: clean activation, ticker OP, bSync=True, 90k cycles 0 errors, timing unchanged (jitter 7.3us mean) - docs: pitfall #10 (DC selection method)
