Delta Controls: V2 to BACnet

[CM3Tech]

Is there anyway of changing a V2 comm loop to a BACnet comm loop??



I am/was supposed to be integrating with Delta controllers that I was told were BACnet, come to find out these are the older controls and they are on a V2 comm protocol.

The old DCU system controller can have two comm cards, one for V2, one for
BACNet. It works like a gateway.

orcaview,

Is it as easy as changing the comm board? I can not imagen it being that easy.

orcaview,

Is it as easy as changing the comm board? I can not imagen it being that easy.

I did several projects with V2 and V3 protocol. But that's 5 years ago. I just hope I can remember the detail.

The old DCU can have two communication cards, one is for V2 panel like turbo panel, one is for ethernet card. It works as gateway to bring V2 to ethernet. Orcaview front-end can be setup to have V2 and V3 through ethernet. You already know how to setup the V3 side. The V2 side need a security panel and password. Normally it's the gateway panel, as #2.

To share the information between V2 and V3, you need to setup the virtual points in that gateway panel.

I don't think you can buy a DCU from Delta now. Delta must have another solution to support the old V2 system.

If you need more detail, I can go back to one of my sites to take some photos.

At the site I am working at I have two DCU's one has all the controls on the comm loop and the other has nothing on it. Each DCU has the DXC, the expansion card to ethernet. Each ethernet card is plugged into a switch.

In the workstation, in the tree there are two different protocols. One DCU is under BACnet protocol heading and the other DCU is under the V2 protocol heading. With the DCU under the V2 heading all the other controls in the building are located.

"To share the information between V2 and V3, you need to setup the virtual points in that gateway panel. "

If I understand what you said, Do i create the same points & controllers that are under the V2 protocol and create virtual points under the BACnet protocol?

Thanks for your help orcaview

Hi, I work as an Automation Tech, for a Delta Controls Rep, when integrating a site from V2 to V3, there are no virtual points. You only need to map points if you want to share info between the V2 and V3 controllers. In order to do this your V2 Panels including the V2 DCU, has to be V2.92 Build21. This done throught GCL, create a program in the V3 DCU and and call it V2_v3Exchange_PG, you have to create some AV's OR BV's or GV's depending on which way you want the info to flow. Now equate these Variables to the points you want to transfer in V2_V3 Exchange pg. Note you have to write to the V2 panel from the V3 Controller. So wrap those statements in DO_EVERY loop, or you will pound out info onto the network on every program scan.

What silversurfer said is very detail. Based on what you have onsite, I think the integration part is already done by someone. Now you have V2 and V3 online. Do you need to modify the project?

[clguy]

My client has several V3 and several V2 systems. What will be involved in switching the V2 systems in order that we can communicate through BACnet/IP over the existing network?

Hi clguy. As silversurfer pointed out; you need an old V3 DCU (I don't know what is used today) to tunnel V2 through, and then you require V2.92 Build 21 (I think Build 26 was the last release), micros were strung off the rs485 port and an ICP required the coaxial cable. The smartest thing to do is to upgrade their V2 systems to V3. Come to think of it, later V2 DCUs could be flash upgraded to V3.

[clguy]

Hi T Brewer, Thanks for the info. I like the idea of having the, upgrade to V# if the budget will allow it. Thanks again! :-)

Hi guys

I work for a big Building AUtomation Company as a technical support specialist. I am integrating Delta panels (V3) using Bacnet IP. There are 3 V3 panels and i can see them just fine!
one of the 3 panel is a DCU050 V3.2 and they have a bunch of V2 controllers also but i cant seem to see them on the Bacnet IP network! I was told that the DCU would act as a router from the Intellinet to the Bacnet IP, if the DCU is configured properly, but i tried modifying the DCU configuration from Orcaview without any luck! Is it doable or not??? Is there any way of seeing the V2 controllers (ICP) on the Bacnet IP or do i have to map virtual points in the DCU that will be equal to phisical V2 points??

thanks in advance

Martin,

It's been a while since I've used ORCAview but here a couple of things that you might want to look into:

1) the Site Settings object (SSx) in the OWS must have the Delta Version 2 protocol enabled in the Application protocol applet.
2) the same SS object must have the V2 security panel field set to a valid V2 panel address in the Advanced applet.
3) make sure that the Username you're using to login actually exists in the V2 security panel - they must match in order to get in.

Try this first. If everything is set correctly, then the problem might be at the routing level.

Hi Frich

thanks for your reply! now i am attaching some screenshots. Where do i enter the Uername and password for the V2 settings?

thanks

Martin

[Martin_SBT]

Sorry, forgot to give you some info! Panel number 2 does exist an the V2.
Now , if i understand correctly what you are saying, this panel number 2 is the V2 security panel for the V2 network! But where do i find out if that User and password is defined or not in that panel??

[Martin_SBT]

ok, the DELTA user does exist in panel number 2! so it bring me back to question number one: Is it possible or not to see the V2 controllers from a Bacnet IP client?

[frich]

Yes you should be able to view your V2 panels from an Delta/ORCAview interface. But not from a BACnet IP point of view. Let me explain.

In the left pane view, in Navigator, you should have a BACnet Protocol and a V2 Protocol under the Delta Network. Is that what is shown when you login ? Once everything is set correctly, you will see all V2 panels (and their objects) under the V2 Protocol and all the BACnet panels under the BACnet protocol. But these are Delat proprietary V2 points. Tou won't be able to read them from a BACnet IP point of view. You have to create V3 objects in a BACnet panel and create a program in order to view them as BACnet objects. Unless you want to share some information between V2 and V3 panels, no programmation is required to read a V2 object.

Back to my previous post, it looks like the SS object is configured correctly.

I guess you logon with username DELTA ?

Then you have to know which BACnet panel is routing the V2 information to BACnet - in other words only one V2 panel should be physically connected to a BACnet panel. What are these adresses ? I gues for the V2 side it will be 2 but what about the BACnet side ? In that BACnet panel, you will find a BCP object (BACnet protocol settings - if I'm not mistaken). Check that object and make sure it is set correctly - you can cerify that by looking in the Delta Controls Technical Manual. Chapter 9 (from memory) shows you the correct BCP settings for different network layout.

Hope this helps. Let me know.

PS: En passant, Régulvar Qc est le représentant de Delta Controls pour la région de Rimouski - ils vont sûrement te donner un coup de main :-)))

[Martin_SBT]

LOL ( i know about Regulvar...lol, guest why i dont want to call them?! )

Thanks much for all these informations! Alors si je comprend bien, je ne pourrai jamais voir le V2 a partir d'un client bacnet IP??

Et oui Frich, sous "Delta" dans Navigator, je vois bel et bien les 2 reseau separement.

Merci Encore

PS: J'espere que tu ne travaille pas pour Regulvar!! hahaha

Sneaky French guys working around the local rep. So do you work for them Frich? That would be funny in a way....

[frich]

No!!! Used to work for them :-)))
