    Niagara CCN Driver

    Hi Experts,
    I wonder if someone can help me with more information about Niagara CCN Driver.
    Unfortunately, I can't get a demo version of the driver on the JACE, and I can't run it from the Supervisor.
    I need to know if I can discover all the tables on the chiller exactly like the NSTV.
    Can I get the alarm history of each chiller?
    Is there a limitation on the number of connected chillers (on the same Bus) and the number of points?
    I heard that the CCN driver had some problems with the early versions of N4 i.e. 4.3 & 4.4, so what about the current versions 4.8 & 4.9?

    The driver is limited, no config tables. I would not waste my time or money with it. Put in OPN converters and use BACnet.

    I believe the point/device limitation is universal for native drivers like CCN.

    I believe if you have one of the older "demo" jaces in your dealership it can run the CCN driver as evaluation.

    There are two version of the driver, below are the features. The Extended mode driver is not offered for sale at this time, believe it is only available to Carrier Corp. Just don't have access to the maintenance & configuration tables with standard. The limit of chillers with fall into the Jace device license count.

    • Upload/download support for display, set point, time schedule tables
    • Alarm handling (display and logging)
    • Broadcast date/time, Broadcast acknowledger, Alarm broadcast acknowledger support
    • Device status support

    CCN Extended (license feature ccn + ccnl)
    • All the above plus
    • Additional support for Read/write/force/auto maintenance table entries
    • Additional support for Read/write configuration tables
    • Additional support for Discovery (learn/create) support for maintenance and configuration tables

    So what about the Alarm history?

    Is there still a dropping of the points with 4.7 and above like what was happening with 4.3?

    You can see ALAMHIST table from the PIC.

    Don't know, haven't used this driver since AX v3.7.

    As hvac69 stated, we have been installing the Carrier's OPN-UPC on CCN devices to integrate them into Tridium over BacNet.

    We also deal with Carrier and have all the tech tools. The cost is less than half of the Tridium driver cost for us, but we have the tools to setup the OPN-UPC for integration in house. To note ... you will not get the Alarm History table with an OPN-UPC.

    If you have to outsource the setup of the OPN-UPC, I believe it should still be less or equal of the driver cost. Then you are dealing with Bacnet in Tridium instead of CCN, which will be a learning curve if you have never done CCN into Tridium.

    I had a play before with OPN-UPC, but can I map the points of several chillers on the same bus using one OPN-UPC?

    The OPN-UPC will hold two control programs, you can pull points from several chillers in one control program. Just need to change the point path from "ccn://link/ to the address of the ccn device. IE: "ccn://0,91/***" and "ccn://0,92/***"

    Keep in mind this is an older controller with limited memory, can't pull everything from several chiller in one OPN-UPC, just pull what ya need.

    open-uc is 10 programs.

    you could use a ccn router (civ-cr) instead of the opn-upc if you have several ccn devices then do bacnet by IP.
    The router can have 140 devices connected and can have programs installed on it. You could upload all your devices and pull the points from the programs.
