Limitation of FM350-2 modules per S7-300?

Hi All

Can someone tell me if there is a limitation for the number of FM350-2 (8way Frequency Module) that can be added to an S7-315-2DP (2AH14) on ET200M modules.

I have an application of 5x ET200M stations with 2 x FM350-2 modules on each station ie. 10 x FM350-2 in total.

The hardware config compiles happily, but I'm not sure if there is some other limitation.

Regards

Philip

Hello DesignTech,

as I see in CPU technical specifications manual, there is recomended limit 8 FM modules per CPU.

But I don't have any practical experience with so many FMs, so I can only check it in manual.

With best regards
