AX device capacity

[sysint]

AX capacity questions. I get differing explanations on capacity for LON devices on an AX box. Is this completely dependent on available resources or are there other considerations? For instance, does the box always consider all variables from a node or is more like the ilon100 where you pick the variables you want to deal with?

I'd like to know a practical average of how many devices an AX box can handle.

Also, can you leverage a AX to utilize IP852 or is this a lost cause because the box is limited?

TIA

What are you up to now?

[sysint]

I can guarantee you it is something...

And here's something cool that's coming out soon. I hope Dear Leader will allow me to own one.

As of Revision 3.2 IP852 is a go.
The white papers are at the bottom of the page.

Does the box have enough physical capacity to make use of IP852? I'm thinking it doesn't.

[sysint]

Which kool-aid whitepaper talks about IP852? TIA.

Hmm. Why do you say that? You need to define "Box" as well.

Be careful, you're walking into a sysint mine field.

He's not after info.

He's thought this AX bash out 40 moves ahead.

[sysint]

nothing like that on this one NINAX. I'm just assembling some practical information on the product. I used to play chess as a kid and about the farthest I would get is 6 moves in advance... so crediting 40 to me is quite the compliment. Thanks

Never underestimate one's opponent. And I still say this is AX bash set-up, or at least you'll try.

Why don't you start out by posting the ilon specs that you are requesting for an AX.

Then expand on which platform & options the AX you want to try to bash should be.

[sysint]

...what's an ilon?

"And I still say this is AX bash set-up, or at least you'll try." Nope. Absolutely not.

[sysint]

I'm trying to understand their architecture and the capacity of each product in a Lonworks network.

The 46th 'word' in your original post.

I believe that response supports my point.
Not served per your plan?

Not sure why the heavy-duty suspicion...maybe I'm too clueless to have ever seen a hidden agenda from sysint...but anyway, my two cents:

As far as I can determine, the LON capacity of the box depends entirely on available resources, just as any integration in the box does. Now, it's still a foggy area exactly how Tridium handles memory management, as Ninax can testify that two disparately-priced JACE models can show vastly different abilities when certain memory stacks are compared ("heap" vs. available RAM) - the whole point is that "available resources" is a very nebulous term.

There's nothing in my experience that indicates that a JACE would have any problem handling IP852, if it had enough memory to function normally (some JACE models seem, well, underpowered...but there's a couple kickin' models that handle anything you can throw at them - I'd have no problem experimenting with IP852 on a JACE6 (with or without expanded memory) or a JACE-NXS).

[sysint]

There's no USB port on a JACE so for IP852 does it utilize the Echelon config server or does it have it's own implementation?

Anyway, how many ASC LON controllers can you dump into the JACE 6?

The JACE NXS has four USB ports...(and they actually work - I've used them with serial-port hubs to expand this particular model to 4 additional serial ports)
(and I'm going to have to brush up on IP852 - I think I'm confused on its implementation - I thought it was LON-over-IP, and I don't know anything else about it...)

I haven't done any large LON jobs with a JACE-6 - the biggest I've done is 40 or so; but I have no doubt that Ninax or Chris W. have some examples of some larger jobs using a JACE 6 (or WEBS-600, or FX-60, or whichever brand they use). However, I do have 75 devices on an original model JACE-545, with the same RAM as the base 600, but with only 1/4 the flash memory of a 600.
How the memory relates to how much stuff you can cram into a JACE is something I've never been able to put my finger on. It's really the processor that seems to impart the most horsepower to a JACE - the 600's 524Mhz PowerPC processor is smokin' compared to the 250Mhz RISC processor used on some of the older models; the 650Mhz Celeron in the NXS is why I like it so much.

Thanks. It seems like you need Big JACE to consider handling IP852. However, if you are maxing out at 60 nodes than IP852 still doesn't help you because you cannot process data from a couple hundred nodes (or more) in a single JACE.

Typically I see a Neuron based FT-10 connection on a JACE. I had thought this was a bottleneck for data as you only get so many packets/second through it. Move to IP-852 connections and that changes dramatically. A competitor to Tridium utilizes Loytec IP852 NICS (which are capable of parallel processing up to 8 MNI's-- 8 LNS DB's) and you start to understand the capacity. This competitor's box also can also use multiple IP852 NIC's. The other nice thing about this is that they can use their protocol analyzer from their desk to view all channels on the network(s).

Wow, amazing what you can learn here. /
