Upgrade a SLC 5/04 to ControlLogix

$

Good afternoon,

I have the following system:

0)        1747-L541        5/04 CPU - 16K Mem. OS401

1)        1746-BAS-5/02 BASIC MODULE - M0/M1 capable

2)        SPARE

3)        SPARE

and I want to upgrade it to ControlLogix.

I was thinking of using a ControlLogix 1756-L81E, 1756-PB75, 1756-A4, and 1756-DHRIO to replace the functionality of this existing system. However, how do I replace the 1746-BAS module? From the program it appears to be storing 64 integers that get copied to N7. What hardware is equivalent to a 1746-BAS? Do I need to get online with the BASIC program using hyperterminal?

Thanks for any assistance.
