i have redundant system of revision 13 of 1756-L55 , CNBR/D and SRM ; with two I/O racks
i try to add 2 more I/O racks but using CNBR module release E and when i try to add this module in the application; i didnt find this type of modules
i figured out that the revision 13 don't have this CNBR/E module and i must use revision 15 or later
please advise me is revision 15 is suitable and compatible with SRM module with F.W. 3.39 and CNBR/D module with F.W. 5.51.1
as i saw in the manuals 1756-RN620A-EN-E that the revision 15 doesnt supported in redundancy system
