Keypads Offline and Online Occasionally

Greetings,

I have a system with 14 MET7 keypads. After observing diagnostics, I notice that a few of them go offline for a few seconds and then come back online. They don't do it simutaniously. Is this to be expected for noramally-functioning keypads?

Thanks.

    I'm curious - is this at a regular interval? Only after refreshing your online-tree? I could see 6Ns doing it only if you forgot they are two devices in one - but not sure on the 7Ns . . . could power be too low?

    Just brainstorming....

    Voltage is good. No rhyme or reason to it as far as I can tell. Here is about a three-hour snap shot of diagnostics. Devices 101-114 are the keypads (IP port 4 is iWeather):

    Any thoughts anyone?
  • jjamesjjames Posts: 2,908
    something I just thought about while driving. First, how many Axlink devices total do you have on the system? Are any other systems using, or referencing them? Take a look at the cpu data via telnet, does it seem excessive? Could you write a function that checks the cpu usage when a keypad falls offline and reports it in diagnostics? Can you monitor button presses within that system to see if a certain sequence causes them to freak out? Could iWeather be trying to send them data?

    I never used CPU usage before. Pretty cool.

    Current reading is 94.9, peak is 99.5. Seems high!?

    Extremely. I'd do a bit of investigating to find out the cause of that if I were you - even if it has nothing to do with the connection issues.
  • TurnipTruckTurnipTruck Posts: 1,485
    Having never even known about the CPU usage test, I'm curious as to what typically contributes to high CPU usage.

    Running timelines? Stuff in the define_program section?

    In my case, there are no master-to-master connections.

    Thanks.

    Anything that is happening on the master can contribute. That includes both firmware and anything going on in your code. As there's not a flood of people complaining about master's suddenly having high usage it tends to suggest that the issue is likely stemming from something in the NetLinx/Duet code on the box.

    The NI-x100's are capable of 404 MIPS (million instructions per second) and the 700/900's 304 MIPS (I think). Under normal operation they shouldn't be pushed to anywhere near this. Generally when you see usage that high it's an indication of some code sitting in an infinite loop.

    Have you run diagnostics with everything selected for the keypad addresses? See if you are getting a bunch of button presses that could be stressing the processor. I have had a couple of the keypads have moisture problems that do funny things to the button circuitry and weird things happen. I had one that was constantly pushing and releasing a couple of buttons 100s of times per second :)

    Also, remember that the 6N's use 2 addresses each. Make sure you don't have any address conflicts.

    Processor usage remains the same with keypads and two ENV-VST-C (all Axlink devices) disconnected from the master.

    One of the system modules has a bunch of IF/THEN in the define_program. I'm going to try commenting out that module.

    The processor here is an NI-2000.

    CPU USAGE USAGE

    This from our head engineer:
    In case you’re not already familiar with this: The CPU USAGE command only gives valid number when the system is started with the “reboot heap watch” command in TELNET. Otherwise it will always give the same numbers which are a snap shot taken at boot time. This mode is turned off at next normal reboot.

    The numbers are obviously going to vary based on what your system is currently doing. If you run the CPU USAGE command several time you’ll see the numbers fluctuate. Having a max of 99% is not uncommon. You average of 60% is pretty normal.

    Here is what my test processor happened to be at when I looked: (System was handling some traffic but not much.)

    CPU usage = 9.71% (30 sec. average = 51.85%, 30 sec. max = 99.96%)

    Here are my numbers during a reboot:

    CPU usage = 96.61% (30 sec. average = 21.10%, 30 sec. max = 96.61%)

    Is that still true for the latest firmware? Our systems report back system health and load info stats, including cpu utilization, to our RMS server. When the systems are under load it appears to be correctly reporting the increased usage. These are all booted into 'normal' operating mode.
  • TurnipTruckTurnipTruck Posts: 1,485
    Maybe someone from AMX engineering could chime in set the record straight about the CPU USAGE command? Speculation abounds right now.
  • TurnipTruckTurnipTruck Posts: 1,485
    No answer yet. Keypads still go off and online as shown in the dianostics snapshot. It seems cpmpletely random. No other errors showing anywhere or correlation with other events.

    Hmmmm?

    I'm still stuck on the whole CPU useage thing. AxLink is pretty rock-solid when its set up right. Here's an out-of-left-field question: Are you using any Duet modules? and if so, What's your Duet memory set to? You might try jacking it up a bit. I've had a few flaky systems mysteriously 'get better' by jacking up the Duet mem a bit.

    Just at thought.
  • TurnipTruckTurnipTruck Posts: 1,485
    No duet modules. I say poo poo to Duet.

    No mention of 6Ns but I'll second this...

    I don't know, but RMS may manage the activation of the monitoring. My test here now looks like it isn't active on the current firmware.

    Idling after normal reboot:
    CPU usage = 99.97% (30 sec. average = 92.07%, 30 sec. max = 99.99%)

    This would indicate it is NOT actually monitoring, the value reported is always the same.
  • TurnipTruckTurnipTruck Posts: 1,485
    Definitely no 6N keypads. The Axlink devices are the 14 MET7 keypads and two ENV-VST-C thermostats.

    Unless it happens inside the RMSEngineMod its not doing it. Everything else has been rolled internally.

    *Edit
    Even within the RMSEngineMod when there's a vanilla system running code which was all rolled internally it appears to function fine.


    *Edit (again)
    Just contacted the TS guys here and they're not aware of any requirement to reboot with the heap watch flag. They're getting in touch with some of the engineering boffins over at AMX HQ for confirmation. I'll post the results when I hear back.
