    I shared with you 1 of our concern regarding the FX40 and JCI support.

    But we have other concerns......

    We have many sites with N30 and M3 with more than 1200 points per unit.
    We have some smaller sites with FX40 with around 200 to 300 points. One of them have about 800 points.

    The graphics are lot faster with the N30 with its 1200 points then he FX80 with 800 points.

    When releasing overwrite in the FX40 sometimes work sometimes not. This never happen in N30.

    Historical Datas, datas acquisitions and stats, the FX40 is limited to its memory, the N30 with Access Historian lets us back data easily for years back of logs.

    Alarms in the N30 works fine, with the FX40 we had difficulties making the alarms working properly.

    Our business is really oriented on complete industrial building automation (including mechanical rooms, compressors, productions, etc) and less standard institutional HVAC.

    Regards
    It sounds like you dont need any input from us. You know N30's. You like them so whats the purpose of the thread? BTW I dont think its possible yet to expose your fx-40 points into M3 with the johnsonized Jace lagging behind at Rev 3.0.106, but eventually you probably will be able too.

    Don't know what you mean by that, loading? If so, the M3 graphics are on the PC, the FX's are in the panel, so data transfer rate/amount would explain that.

    Never have seen this. This might be an operational training issue.

    You're comparing apples to oranges. Get FX supervisor and it will do the same, yet better.

    Alarms in the N30 works fine, with the FX40 we had difficulties making the alarms working properly.
    Again, I would attribute this to a training issue/learning curve.


    I kinda agree with freddy-b. What was the exercise for?

    About the slow graphics on the FX40 the refresh rate seams to have hard time to pull many VMAs and VAVs over the N2.

    HalreyAl and freddy-b:
    I understand our point about the confusion it may make.

    We had so much problem with our firsts installations of FX40, my boss always want to have the N30 instead (if possible).

    I try to get the whole picture to explain clearly the poors and cons of boths N30 or FX40. Also why the problems we got with our firsts FX40 installations should now be resolved now?

    About the FX Supervisor (may be I missed a part in the FX training) but what I remember is the datalog history (alarms, trends, etc) is located in the FX40 memory. The maximum history I get is around 1 month max. Could we have a FX Supervisor running on a computer to pull trends and build larger trend histories?
    Is it part of the Workbench, Workbench Pro or Workbench Server?

    Yes.

    FX Server is the JCI version, FX Server includes Workbench.

    FX Server

    If I understand clearly...

    FX Supervisor (for history stored on a PC) is included in FX Server only.
    Because Workbench Pro is only to programming tool doesn't have this feature.

    Workbench is the basic version
    Workbench Pro is including the basic Workbench.
    FX Server is including the Workbench Pro and it is the top end software running on a pc not only for trend histories but it may also act as a FX40 gateway to share data/points between different FXs.

    Is it right?

    Thanks

    To the point...
    I am an independent consultant with 25+ years working with Building automation systems from across the industry and around the country.
    At one time or another I have worked for most of them.

    My experienced opinion...

    The FX-40 is the best choice if you already have existing N2 devices. The FX can be serviced and supported by any number of vendors, is the least expensive option, and is a user friendly system.
    The NAE is much more cumbersome to use and setup, and is generally more expensive. The NAE is also only available through the local JCI branch office which locks you into a sole provider for service and support.
    The N30 is no longer in production so cannot be replaced if fails

    All existing JCI N2 devices are compatible with the FX40 and it can also talk to existing N30's over BACnet if desired. (Don't know why you'd want to though)

    If existing JCI N2 is not an issue, then you can select any Tridium Jace based on controller and point counts you plan on

    If it's the M3 graphics your hung up on --- Iconics is the company that wrote the graphics package for the N30\M3, and their current product can be incorporated into the FX40 graphics (Again - Don't know why you'd want to)

    You will need FX-40's with "enterprise connectivity" (LP-FX4021)if you want to share data between 40's (Outdoor air for example). If not use the LP-FX4020

    If you plan on heavy trending and alarming get the server package. It is simple the full blown software package running on a PC that is dedicated to your system. This allows archiving to the hard drive of the PC.

    You would not need any other software if you purchase the server package.

    I have many sites on line in different parts the country and have permission from my clients to demo these on occasion. Please reply if you'd care to " go for a drive"
