İs it possible to use 8 Modules with 32 Inputs /Outputs Each?

I have One simple Question,
Let me say I have S7-1214C And the max I/O Modules in my rack  are 8. my question goes like:
Does it really matter If I use  8X32 24V DC Or 4X8 24V DC,  I mean İs it possible to use 8 Modules with 32 Inputs /Outputs Each.  
What is the total Number of the Inputs I an use with modules. 

Thanks.

Split from what's the maximum I/Os in S7 1200.

Hello,

For the future - indicate the order number of the product in question

Simple question - simple answer

See:

You have an area of 1024 bytes for inputs and 1024 bytes for outputs, which means that:

1024 * 8 (bit) = 8192 digital inputs and 8192 digital outputs

or

1024/2 (word) = 512 analog inputs and 512 analog outputs

This is all in theory, in practice it is necessary to take into account your technological process, tasks - in order to understand how many inputs and outputs you will need.

Process image in a PLC means that this is all the possible number of output inputs that your PLC can process - regardless of whether it uses rack-mounted modules (1200 modules) or uses distributed peripheral modules (for example modules from ET200SP)

****************

When using a maximum of 8 modules with 32 inputs (for example), you only need to take - 32 bytes of the process image.

Therefore, often S7-1200 is used in conjunction with a distributed periphery...

 No it doesn't matter either you use 8 modules with 32 bit IO or 8 modules with 4 bit IO. By the way S7-1200 series have 32 bit IO card in only SM 1223 series with 16 DI and 16 DO available on 1 card so by this you can add 256 IOs with signal modules and CPU on board IOs on S7-1217 CPU is 28.So total no of IOs you can use in an S7-1200 system without distributed racks are 284.
