Allen Bradley Ethernet/IP Mapping Size Limit?

$

Here is one I don't run into too often:

 

Does anyone know what determines the maximum size of the EIP map when you define a new EIP slave in RS Studio 5000 as a slave?

 

My slave device can map over 352 DINTS (704 INTS) or (1408 BYTES / SINTS)  , however Allen Bradley only allows 125 DINT Input/124 DINT Outputs. (Or any combo of INTS/SINTS)

 

What determines this maximum setting here given from the vendor EDS file that is limited in the EIP Connection Setup?
This also happens when you setup just a Generic IP connection without an EDS file.

 

I can not map the entire INPUT Map of 352 DINT Inputs and 352 DINT Outputs from my Slave to the Allen Bradley PLC is the main question.
