Entire system to NCE both processors?
Frank

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,

Yes.

Thank you,
Frank

Might I ask Have you addressed the issue of the FEC side being at 100 usage yet....

Thank you, what is recommended or standard range?

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

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.

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,

1. NAE part
Recomended object quantity on NAE part of NCE :2500objects - including network objects
Recomended network objects per ms/tp or n2 trunk : 1000
So for example 1000 network objects +500alarms extensions+ 100 trends extensions=1600 objects
And if you using FEC part and wan't to see it's network objects they are added too on internal ms/tp trunk.

2. FEC part is independent from nae (they could be a different releases)
there is no object quantity in FEC part - there is only memory usage

You got it !

The CCT is only the programming part of the NCE - think of it as a field device like the FEC. The NCE contains 33 Inputs and Outputs and can contain up to 1000 objects. When you open the CCT program, it will tell you the % of memory used and should show a green or red panel or button - something like that. If this is fine, the objects in the CCT are okay. The next part to look at is the NCE objects which are from the CCT program (exposed on the MSTP trunk) trends, alarms, programming, and anything else which is done on the NCE.

Hope this makes sense

Thank you very much for taking the time and trouble; it now make full sense.

I did use it thank you so, so much. Feel like I can't catch up lately.

Much appreciated,
Frank

so, you haven't used JCI literature repository...i mean the product documentation website ?

i can send a private message of that URL to you...but i don't see an option to send PM
