Can someone help tell me what's the difference between a 1747-L531 and 1747-L531E? I need to buy a spare part but I don't see a 1747-L531E in the pricebook although you can select this processor in the RSlogix500.
Thanks
DW
 
L531E has OS302 Series C firmware, which (among other enhancements) allows use of Block Transfer instructions.

It is simply a later firmware revision, and if you order a new SLC 5/03, you'll get the latest firmware anyway.
