Hi everyone!

The system is 02 CPU S7-400(6ES7 414-4HM14-OAB0 V4.5) and a slave IM153-2(6ES7 153-2BA02-OXBO).

I want to add an analog card on the rack of this IM153-2,i know i must stop the installation to do it.

The system ask me:to wich H-CPU do you want to download?

So wich one and i want to know if there is a document to do this job correctly.

PS:Before adding the analog card on the slave,must i remove the power on the rack of the slave?

Thank you very much for your help.

Hello,

Please have a look at the following link:

See paragraph 17.5 (To add hardware)

Are you using an Active backplane on remote IO station?

Best regards,
