If you do a save as you can make numerous points in very little time most Trane techs don’t even know about that option make all of your common points at a time then change to a different set of points and so on it’s still going to take some time but a simple integration vs a complete conversion for now then get your customer planning for a capital improvement.

thanks, I sent you an email since I'm a new member and can't figure out how to DM. I put my email in my profile.

Hi scrooloose, do you still have a station program that pulls BCU points?

Else have you heard any programs/tools that create the BCU points automatically? I'm sitting here with 170 VAVs and a handful of RTUs and certainly don't wont to create the points by hand.

Thanks!

It is suppose to do this for everything from Comm2 through Comm5 and all AI/AO BI/BO etc....

Is there anyway I could get a copy of this station and if you know how to get a hold of this program I would greatly appreciate it. Wow would this make life easier.

Essentially the BCU has the native bacnet points in it for everything, its just not discoverable. So long as you know the address of everything internally, you can see it just like Tracer ES or Tracer Summit.

It is a software program that sits on the supervisor and creates the virtual devices. Least that is the one i dealt with was.

From what i hear they were having problems writing to it, but could read everything fine. So maybe they got past that hurdle.

Hmm...could you email me the JACE station that you are referring to that can read Trane BCU points without manually creating the BACnet points in the BCU. Curious how this work?

Thanks

Good luck

are you talking about the comm bridge?

Summit to Niagara, Backbox option

I have done several jobs removing the BCUs and using the infocon drivers. Everything went very well and that is the route I would go. I would not replace the few PCM but would leave then in the BCU and just Bacnet IP those points out for now but if the cost is not an issue then replace them. Building the points in a BCU is a real pain in the butt and at best takes a minute a point which at least based on the point count you have is a weeks worth of labor. Could probably replace the BCUs and PCMs in less time. Not too mention they get a much better system with the Jace than anything Trane offers at the time.

Between the 2 BCUs I'm thinking its going to be somewhere around 2000-3000 points to map to BACnet! I'm afraid I might go crazy mapping that many points! The other route would be to rip the BCUs out and install 2 JACES, install either LON or BACNET interfaces in the CSCs (if there upgradeable) and use infocon comm4 driver for the vavs and replace the couple of PCMs with BACnet spyders, then hit the Discover button and never look back. Going this route I would hopefully never have to deal with Trane again, nor support the junk BCUs.

What ya think. Anybody ever installed the trane Lon or BACnet interface in a 2001 year model CSC?

The 250 point number was the limit for a BMTS BCU with a serial card.

Also, you can do BACnet/Ethernet or /IP with those BCU's. And I don't think removing the BCU's would be any faster than creating points, especially if all they want is a web interface.

There are two slots behind the modem/ethernet card. The bottom card slot is standard cap, and the top card slot is for high cap.

Point creation is very consuming, it will take a long time. If you are fast and you can create a point a minute including referencing it then you can do the math.

You could always use the comm4 driver and just get rid of the bcus, then upgrade the few units and pcms that you can't pull in.

How can I tell if it has high cap cards? Thrashing the BCU hasn't been ruled out. Is there anyway to communicate with CSC other than comm3? Lon or BACnet?

Trane Summit to Niagara AX

Building has Summit and they want to get it to a web based system. It has 2-BMTW BCU's and a summit workstation onsite, its my understanding that i would have to create all the points as bacnet points and pull them into niagara over bacnet/ip. How time consuming is the point creation and how many points will the BCUs handle? Its seems I have seem a number somewhere around 250 before, the non-volatile memory on both is around 70% and volatile memory around 65%. The building has around 138-VAVs, 6-CSC's SWUDs, and a couple of PCMs for lighting and tower/pump control on each BCU. Sound like a lot to me? If you don't think this is going to work then I will have to look into Plan B and at this point there is no Plan B......

Any advise is appreciated.
