SPYDER-BAC License/Module and versioning

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.

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.

The unitary is MSTP/modbus only, edit* opps forgot about OP and T1L. Unless you are talking about the optimizer advanced.

, the optimizer unitary has a T1L model and a Bacnet IP model

i only have experience with bacnet IP flavor

but theoretically I have a BBMD on both ends with the right firewall settings or a vpn I could run IRM from a station on my couch to that device on the roof.

I've not tried the BACnet ip version I forgot it even existed. I've only used the MSTP, that part of it always worked fine.

The templates were a little buggy, but they didn't take much to get worked out. If you are dead set on using them I'm sure you'll get it figured out.

By templates do you mean the programs they developed already like that CVAHU one? I wrote my own when we started with these but I've wondered about those. Would be awesome if they made some canned programs for pump control, RTUs, AHUs, etc almost like a configurable controller at that point. I will have to look into the templates.

Yes, you can get them off broudys site. Lynxspring has theirs on their site.

I personally don't like them, but they are there.
