    This doesn't mean it always can happen, but what does going over the object quantity take away from in other areas? Does it reduce the capability of any other functionality of the system? If it is design recommendation limit, there must of a been good reasons, to stay within their recommendations.

    I think after this I will pretty much have a good understanding, thanks to all of you of this issue.

    Thank you all again,

    Just think of the NCE as your PC. You have ram and certain amount of programs. If you start adding more programs, the PC gets slower. To much and it really starts to fail. Same as the NCE. The object count is what JCI feels is a good amount for the NCE to operate with in a timely manor. Once you start to go pass this, things start to slow down. If you look at the NCE and alarms, you'll see what the CPU, memory and other things are set at. These are the limits of the ram etc in the NCE. Once it starts to go pass this, you are having issues. So you might have 3000 objects but the NCE memory, CPU are in check you won't have issues.

    Another thing which you have never talked about and is a factor, is the COV. This is the change of value and will impac how hard the NCE will work.

    Which change of value? Can you explain a little more. I know about a point change of value?

    Thank you,

    Ok, this is my question, does or CAN the overage of the object affect the CPU, Memory ? If so what directly and what issues for example may we have. Then I think I am pretty much done on this.

    Thank you so much, you gave me a quick class. Much appreciated. Amazing knowledge,
    Frank

    COV happening for the points in NCE, you can check it at the "Diagnostics" tab of NCE....find out the value COV/min..

    I need clarification:
    NCE is one controller that has two separate processors. 1) supervisor device *ours states the object count is 600. 2) branch tree underneath the NCE supervisory device labeled (NCE-AHU) its object count is 2300.

    With an NCE only, where does the recommended-maximum object count add from the the NCE supervisory device or the FEC part of the NCE or both NCE separate processors recommended not to exceed 2500 object count?

    NCE's can be a little confusing since they are two processors in one.

    Thank you,
    Frank
    Thanks,
