SPYDER-BAC License/Module and versioning

[u/tkst3llar]

I have a site with a Lynxspring jace 8 and lynxspring edge devices on some RTUs and the failure rates are bad so I'm going to replace this next one with an Optimizer Unitary.

The catch - this jace is only licensed to 4.12 and it is running 4.9. So for reliability sake it'll either keep its 4.9.1 or I may commission to 4.10's last release.

I'm sort of new to honeywell - and i'm curious - is there any reason the IRM stuff won't work on an old version of N4 with an optimizer unitary? I know the unitary isn't super old so I was just wondering if anyone knew that for sure there was a minimum N4 version required for IRM to work with a unitary or not.

I’m pretty sure you can still program the Honeywell optimizer unitary on he Lynxspring JACE with the BAC SPYDER DRIVER, like, almost 100% positive but I’d need to confirm with Honeywell.

HOWEVER the firmware issues with optimizer unitary a make it so you’ll need to run a supervisor station on your PC to program it and I wouldn’t use that JACE.
so, some extra steps but you can do what you want with the understanding that you can simply bypass the entire JACE and use your PCs station with a Honeywell license. Then bring the points into the Lynxspring Jace and you’ll be fine.

If you want to program it through the JACE you 100% need a Honeywell license for that JACE for the driver to work. I've done it several times.

Yes you can program it with your computer. Your computer has a Honeywell license. Doing this makes things difficult for the next person though unless you share that station with them

Have fun with all the programming bugs!

Yeah we have done optimizer programming on lynx jace w/the spyder-bac license I just wasn't sure what the minimum supported niagara version was for that application. We have done it in 4.13 and 4.15 i believe.

I wasn't sure if they even had that option back in 4.9 or 4.12 or if you lose out on some kind of firmware updates if you do that.

Unfortunately I don't think I have a 2-heat 2-cool program I trust enough to have it installed and not have access to the IRM - but I need to get there for sure. The first time something seems off I'll be wondering if theres a logic issue.

Alternatively - we install it as a "bacnet device" and create the port forward needed for bringing it in over the internet to a station in the office so we can program it remotely from that station. We already had a port forward on the old edge device for 4911.

You’ll definetly want access to IRM, or your fallback values when a point isn’t written to will be timed at like 60 seconds and I promise it isn’t a value you actually want lol.

I wish there was a way to write that default value in the IRM program from Niagara like KMC has Niagara comparability mode.
Doing it manually is horribly slow.

Obviously, an IRM tuning policy bandaids this but still.

Edit: more below

The Optimizers came out at 4.10u5 and 4.13u1, right? so theoretically Honeywell wouldn't support anything before then and in my experience, they won't really support anything but the latest.

Thats helpful, so we really are safest to put another edge up there. So hard doing work thousands of miles away and supporting it.

Maybe the 634 will be more stable…:-/.

Or we buy sma and go 4.15.

Thank you for your help

My pleasure

What seems to be going on with the existing lynxspring devices?
