Pretty new to I-VU. Got sent down to a location today. They are having issues with alarms spamming system and remote emails/phones.
General issue is any alarms coming from a few older 6400's will just keep populating. You can ack and/or delete them, but they just keep populating. The time stamps are from weeks ago. They are return to normal alarms. I tried removing the return to normal alarming, they still populate. The only way I can get it to stop is to disable the alarms.
Any idea? Sometimes you will get 3 of the same alarms. This is not happening with any of the rest of the controllers. And I manually tripped an alarm on these controllers and it now does the same thing.
Use NSTV to determine where the Alarm Acknowledger is. While your at it, check to see that you have 1 Broadcast Ack per bus and only 1 time Broadcaster. It sounds like the controller that is re-sending the alarm is not getting a confirmation back from the Alarm Ack, so it just keeps resending.

But I tried to get into the controllers with NSTV and it's a problem. I have the USB to CCN converter. I have all the drivers installed. The Link light is on. Status light in blinking. But Error light is on. I tried a RJ14 and RJ25 cable, both do the same thing. Both cables, I made and are straight pin to pin. I tried scan the bus, but found nothing. Opened up bus scan and all there is are collisions.
Any idea what I'm doing wrong?
Need to check the basics. Need to have one (and only 1) Broadcast Ack on each Bus (including Bus 0). Need to have 1 time broadcaster and 1 Alarm Ack. If you don't have these setup, then you are going to ahve all kinds of problems on the 485-side.
What Controller are you connecting to? A 6400? If so, what is the Version of the Firmware?
What are the alarms you are getting? There are no default alarms setup in i-Vu other that communications for a CC6400, all other alarms need to be setup and programmed in the CC6400.
As previously stated, what is the firmware? Some of the really older CC6400 need a firmware upgrade to be 100% compatible with i-Vu.
How are the alarms setup in the controller and in i-Vu? With i-Vu and CC6400's I have found that they work better if I allow i-Vu to handle the alarms. I turn off the Alarm Processing [ALMPROC] in the configuration so the CC6400 does not broadcast the alarms to the network. Then mapped the Alarm Status [STATUS] from the maintenance table. Once mapped to i-Vu, setup the alarm in i-Vu.
In addition to verifying the CCN acknowledger's as previously stated you can also check for the following acknowledger's in i-Vu, not sure if you have a Standard or Plus ....
In the system options under the General Tab are the following checked ...
1: Allow CCN Gateway to acknowledge alarms from CCN serial network
2: Allow CCN Gateway to acknowledge alarms for CCN/IP network
If a Plus, also look at the Ethernet & CCN Alarm Acknowledger's in the Router/Link "User Config Table", the are ALRMACK1 & ALRMACK2.

My problem is I can get the usb to ccn converter to work. Like I said the converter is showing a error light.
Any time Ive had the error light come on it was a problem on the bus... a short or damaged device ect. Plug into the 6400 and disconnect the it from the bus and see if that helps you
One other question......the version of NSTV I have is 2.02. Is that the most current version?
Looking through some older posts.....there was mention of a 2.2 version?
I also can't get on hvacpartners....my company's login constantly needs to be reset, because other techs don't disable popups and try to log in multiple times.
A little update.......I had to go to another site today. They had a 3v VVT zoning system. After some messing around, I ended up trying a cable from one on the telephones in the office. And it worked. I was making my cables wrong.
So I ended up getting some time to go back to the OP job. The one controller I kept trying to connect to still didn't work. So I tried another. Finally was able to see the controllers.
So that leads me to my next question.........I got an error message, while uploading some on the 6400 controllers. Here's a screenshot-
