AC800M HI firmware downgrade
as far as I know, the firmware versions available for download and installation from Control Builder to the AC800M controllers depend on the current system version. That is, a system version has only one firmware version for each controller model.
I have a system with SV5.1 FP4 and when I try to upgrade the firmware of an AC800M HI, the only firmware version that is available is the version I believe belongs to FP4 (FW865HI_NON-CERT 5.1.1110.3 2013-03-04). But this one is not listed as safety certified in the AC800M HI certificate (3BSE054960_L_en_System_800xA_Safety_AO63111C-A2_Annex_2_Revision_2.11.0_on_TUV
How is one supposed to install a safety certified firmware version for AC800M HI controllers in a system with SV5.1 FP4? Can the certified version be downloaded elsewhere?
Thanks and regards,
