    OLD JCI FPU Controller

    Gents,

    Anybody remember the FPU controller made by JCI in the early '80s.
    I have a migration from NCM s2 bus to an NAE and am trying to figure
    time that it will take to do this. The real Q i have is mapping bi/bos.
    I have the ddl files but i am seeing sst101 and sst102 objects. I do not
    know what these are. I have an idea but I am not sure.

    Any takers??

    The SST101 and 102 are binary output cards with feedback.

    O.K....

    Are they physical cards? How about binary inputs. Are the sst card a dual BI/BO card?

    They are physical cards in the FPU. I believe if you look in the DDL, you will see a BO and a BI set up to reference the same FPU slot. Are you using an NIE and keeping the NCM or going with an NAE?

    Sounds like its already been integrated once already to the NCM S2 trunk from a JC85/40 showing my age here but the stuff was solid thats 25 years old man!.What other field devices do you have? Any DSC8500? Those SST-101 work on 12 +- VDC The Reaper brings up a good point on the NAE vs NIE I don't think the NAE will talk on the s2 trunk to the FPU's. You may have to keep the NCM.
