Can we replace a IMMFP12 with a IMMFP03
In our V94.2 analdo units in PCU11 Mod2 ,we have several module faults and some times as soon as first MFP12 has a fault, redundant MFP12 catch a fault too and we have not enough time to reset the card then we have a plant trip beacause of two mfp cards fault.
We have checked every thing like: power supply and we have changed every thing IPMON, IPSYS, MFP, RACK and we couldnt solve the problem.
Now we want to replace IMMFP12 with IMMFP03. My question is that may this cause any problem if we do the procedure like this:
1. Taking backup of IMMFP12 modole.
2. Replacing modules(main and redundant) with new initialized IMMFP03 modules.
3. Restoring logic on IMMFP03 modules.
