Can we easily replace D445-1 by D445-2 module ? Will the old memory card work on the D445-2 controller ? 

What about replacing D445-1 by D445 , can it be done without issues ?

 Sorry, not sure about the difference between D445-1 and D445, they are the same.

If your old D445 is broken, just pick a new one and everything will work.

If you want to change it for a 445-2 then you have to do :

1) Change of the controller in the project. If project does not allow the usage of new controller (FW<4.3) then you have to upgrade Scout.

2) Change firmware in the CF

3) Redowlonad your project

 You mean the D445-1 is interchangeable with the D445 easily ? without any software modifications ? 

Sorry, but there is not difference between the D445 and the D445-1 meaning that Siemens made :

The D445

The D445-2

So the "D445-1" means exactly the D445 model
