Onb# correspond with the on board IO available
1 correspond with A
2 correpond with B
Please refers to the technical datasheet Pg6
Ext# correspond with the IO expander option
1 correpond with A
2 correpond with B
3 correpond with C
4 correpond with D
Please refer to the technical datasheet Pg7,
here is a link:  http://www2.schneider-electric.com/documents/product-services/en/product-launch/powerlogic/ION8650_datasheet.pdf

1. Identify the feature set A,B or C
B for M8650B4C0H6C7A0A - ION8650B
C for M8650C4C0H6C7A0A - ION8650C

2. Identify the on board I/O
A for M8650B4C0H6C7A0A - Onb1
A for M8650C4C0H6C7A0A - Onb1

3. Identify the IO expander option, if necessary.
As an example if the IO expander part number is P850EA2, then A for P850EA2 equals Ext1
If there is no IO expander then select an ICD without Ext.

With the example above
For M8650B4C0H6C7A0A load this ICD file SE_ION_8650-B-Onb1-Exp1-F01_E1V01
For M8650C4C0H6C7A0A load this ICD file SE_ION_8650-C-Onb1-Exp1-F01_E1V01
But again this is an example only and the ICD file might differ depending there is an IO Expander
