Hi, a couple of times now I've had different PLC's of this type stop when downloading PDiag. One went with a warm start (stop was caused by 1000mS cycle time, called OB80), second all LED's on the front were blinking & could not communicate with it by any means so could not interrogate it, even after a power cycle & removal from the rack. Had to replace it.

I've downloaded PDiag many times to PLC's without any issues before.

I'm running Step 7 V5.5 SP3 & PDiag V5.3 SP6.

Has anybody had experience of this or knowledge of possible causes?
