Hello Everyone.

Hello everyone  I have an S7 400, in which, with the absence of power,the Slave 9 returns with failure. then I download the hardware and the system returns to normal. however, whenever there is a power failure,the slave 9 always returns with the fault: "module available and not ok" someone can tell why it always happens on the same slave. I've done save, save and compile.

Hello Everyone.

 Hello Lhm250,

What Slot is faulted in DP Slave 9.??

I see that you have ASI Master CP Card in Slot 11. Did you after the configuration of the ASI Master upload the ASI Master Slave configuration to the HW configuration then compile and download?? 

If you open up the Module properties you should see a Tab , where you can upload the saved configuration on the ASI Master to the PG. (then save / compile and download)

It may be that ASI Master configuration in your HW does not match the saved configuration in your ASI Master.

Hi,

Can you confirm the AC supply (AC 120/230 V) to all cards are through UPS. Failure of this supply will not guarantee proper functioning of card. 

this is the problem. there is no UPS.

which I don't understand, because the fault appears where I made the change.
