Can someone confirm if its possible to download the hardware config to a running pair of 412-H CPUs without stopping them both at the same time.

If possible I need the CPU to run continually, I know I can stop 1 CPU and download to that for program/memory card changes, but I believe this is not possible for the HW config

My CPU is currently running using profibus comms without an IP address. I would like to add an IP address?

hi,

It should be possible. Have a look into the manual, chapter 17:

SIMATIC Fault-tolerant systems S7-400H

hope this helps,

regards,

Hello AutoGen..

Yes, such downloading is possible

First download in Secondary PLC and then download in primary PLC.

No need to transfer the modes to Stop.
