CI854 firmware downgrade failure
We've purchased two CI854B for a 5.1 FP4 800xA System. The CI854B's came with firmware version 6.0.0360.0. If I use the CI854B with a PM860 with firmware version 6.0.300.21 (800xA System vesrsion 126.96.36.199) I can 'see' it (see 'MILAKI-CI854-FW-01.png') . If I use the CI854B with a PM860 with firmware version 5.1.1110.3 (800xA System vesrsion 5.1 FP4) I cannot 'see' it (see 'MILAKI-CI854-FW-02.png'). Whe I tried to downgrade the CI854B firmware I got a 'Firmware tranfer error' (see 'MILAKI-CI854-FW-03.png'). How can I downgrade CI854B firmware to 800xA 5.1 FP4 ?

Directly from 800xA hardware selector :
CI854B = Only compatible with System 800xA 188.8.131.52, Compact Control Builder 6.0.0-2 and onwards.
Please see Product Update for more information
So you have to upgrade your AC800M to such versions, in order to use CI854B. That is confirmed from your test with 184.108.40.206
Otherwise, if you want to keep ver. 5.1... in your system, you have to order the following:
CI854AK01-eA PROFIBUS DP-V1 Communication interface
Recently we ordered such and I can confirm it is working well with AC800M Compact 5.1
