Omnistat2 to HAI OPII (current FW)

Pete, that's very odd. I have a hunch, though... try disconnecting your OPII from your network for a day, and see if your thermostat behaves during that day. I'm thinking that if something on your network is jabbering, data link layer processing in the OPII may be tying up its CPU to the point where task scheduling is being thrown off. I'm not sure about this, but I'm guessing that the OPII does all of the RS232 framing and start/stop bit processing for the thermostat bus in software, and if there are tasks which are overrunning internally, it could screw up the thermostat bus, and that would also explain the time of day anomalies you're seeing. Of course that doesn't explain why it works with the RC80... but maybe the RC80 is better at ignoring transmissions with bad framing.

(Also... you have secured your wireless network, haven't you?)
 
Thank-you for the advice cornutt.

There's a lot on the network; but no beaconing from any NICs that I know of; I did have a 24 port switch's power supply go and it might have been going over a week or so. Since then its been replaced and all is well. I thought that was the problem for a day or so.

Pretty much everything is wired except for when I use the laptop or touchpad; I could take it off the network as I really only use PCA with it via the network. The network is mostly Gb now and wondering if maybe that's an issue?

I was testing 2 new devices on the network and those were removed today; wondering about those now?

I never saw any issues similiar with the RC80.

Everything is back to normal since resetting the Omnistat this morning. Time is sync'd and no comm issues with the thermostat.

The same issue has occurred maybe 3-4 times since installing the Omnistat2 last fall.

HAI was very patient regarding the concern and replace the thermostat three times in a span of about 3 weeks a few months back.

I'm thinking I won't see the issue again for a while. I can put the OPII on its own network.
 
I guess I could test the NIC on the HAI OPII by putting it on its own network with a packet generator and look see if I can make act up.


I would not really ever would have thought that the network inteface would have much to do with the serial bus though.
 
Does your Ethernet switch have a management interface? If so, see if you can log into it and check the network stats. If you're getting a bunch of frame overruns or collisions, that would indicate a problem on your network somewhere.
 
Thanks cornutt.

Cheapo Gb switches. I can though put the OPII panel on its own physical network.

Whatever it was that was causing it is no longer causing it. It seems to have been "fixed" by resetting the thermostat.

Before I go playing with the network which I really don't believe there's an issue with; will wait for it to occur again and see if I can make the problem go away by

1 - resetting the thermostat (which is kind of a pain if its programmed)
I have reset it before; so at this time it is no longer programmed. (its a WAF thing).

2 - disconnecting the HAI panel from the network or moving it to another network with its own switch.

3 - downgrading back to the RC-80 and not worrying about it anymore.
 
The OPII panel time went off sync the day before yesterday. It was approximately 45 minutes or so off. Enough to notice the lighting schedule was off. I'm guessing that it took one day in that the previous day the lighting schedule was fine.

I set the time last night and disconnected the OPII from the network. Looking at the time via the Omnitouch; it appears fine this morning.

8 or so hours later the time is still fine.
 
Its been fine now for the last three days with the NIC disconnected. I've also noted that I do not get odd occasional -40 temperature readings on my OmniTouch screens. An occasional look at the screens would show this so I'm guessing it was occurring with some frequency. I don't know if disconnecting the NIC has anything to do with this; but HAI clock is keeping regular time now.
 
I connected the NIC interface yesterday for real time status for a bit. Time is still fine and I haven't had any issues with the NIC unplugged. I have left the serial interface to HS plugged in. I will plug in the NIC today and leave it plugged in to see what happens.
 
Updated the FW and PCA (Version: 3.9.0.631) last night. FW is now at 3.9. I also left the NIC plugged in.

PCA update was non eventful. I did not see any errors this time.

The PCA update on the W2003 box showed an error; but was innocuous.
 
Now I've been just watching the network interface on the HAI OPII panel. I've left the network connected plugged in with the FW upgrade.

This morning the interface went "dark" not responding to pings for about 15 minutes; which to me is an odd thing.
