Hot-swapping of I/Ocards

Hi,

I had a question about the condition for hot-swapping of the SM-300 cards in an ET 200M rack.
as it is mentioned in S7 catalog, maximum bus modules in an active rail for this functionality is 5 (attached file).
I have used IM153-2 card with the order 6ES7 153-2BA02-0XB0 and a 620mm active DP DIN rail for ET-200M (6ES7 195-1GG30-0XA0).
now the questions are:
1. is this mentioned FIVE, includes IM153/IM153 bus module also? or only refers to the number of I/O bus modules?
2. this IM card is capable of maximum 12 I/O cards in a rack, according to its spec. therefore, it needs 6 active bus module (6ES7 195-7HB00-0XA0) in its rack. do I lose the hot-swapping function when using this 12 I/O card?

Thanks in advance for your help and guidance

HelloForoogh,

It's just a small mistake in the catalog.

The 5 bus units in the catalog applies only to the 48cm rail.

Please, check the descriptionherewhile the 62cm rail doesn't have that 5 inits description.

In theET200M manual, the maximum is 9 bus units (mixed 1X80 and 2X40).

I've done some projects where I pushed the IM15-2 to its limit (12 modules) and hot swapping was still working.

If this is a new project that won't start in next 6 months, then I recommend to wait forthe new IM153-2BA10.

Best regards,
