Can S7-1500 be used in Multiprocessor Mode?

Hi, 

For the same situation, can S7-1500 be used in Multiprocessor Mode?

------------------------------------------------------------------------------------------
Split from Aspects to migrate S5 to S7.

Hello syd;

The largest, most powerful CPU928 (the CPU 928B) had 64 kB of work memory, non-expandble, for code and data. This is why Siemens proposed ways of coordinating more than one CPU to control a large process (the coordination module 923c). 

The smallest CPU of the S7-1500 family (the S7-1510) has more program memory (for code) than 2 CPU 928B, see the screencapture below taken from the sSemens Industry Mall:

If you decide to replace your S5 controller setup with any of the current S7-1500 CPUs you should not need to use multicomputing (multiple controllers sharing the load of a project on a single rack). You should be able to reprogram the project in a single processor.

In any case, s7-1500 does not have the multicomputing option. The only S7 family that does is the S7-400:

What is multicomputing mode and what are the differences to operating in the segmented subrack?

Hope this helps,
