AC450 CPU Load

Hello.

In our mill we want to change S400 I/Os to S800 I/Os at a AC450 Controller.

Currently the AC450 CPU load is at a high level therfore changing to S800 should not further increase the CPU load.

For S800 hardware i found a ABB guide to calculate the CPU load of the new components.

Does anyone know if there is such a guide for CPU-load calculation /S400 available ?

Hi Herbert,

Unfortunately you will not find any guide to do calculate load of S400 I/Os on AC450 as they are design to use with MP200. In my experience you will find a little increase of load replacing the I/O for S800 because the AF100 network has a faster network cicle. The problem to do it in a high load system is you will not have chance to test you implement nor change it by groups. Is really better to decrease your load before do your I/O exchange.
