Hello Siemens Team

I want to buy one CPU-300 or CPU-400 Serie and one IM153-2 and some IM modules. I don't want to use bus connector and IM153-1 because my system must work when I'm take out each IM modules for maintenance and … .

1- can i install just one IM153-2 on 6ES71957HD100XA0 and other modules on 6ES71957HB000XA0 ???

Actually, i don't need Redundancy in IM because i have just one CPU. i just need removal and insertion function during RUN operating time.

2- Can i install one IM153-1 on 6ES71957HD100XA0 ??
