i have a machine with an NCU 571.3 which was defective.

The NCU was replaced by a new NCU.

When we startup the machine the HMI is not starting up in order to be able to load the NC and PLC of our machine.

We use WINPCIN to load the NC and PLC usually but this is done through HMI.

How can we load the NC and PLC if the HMI does not start up.

Split from Communication to NC failed , password entry only possible for MMC.
