Based on the internal wiring of the FBXi, it appears like it is a half wave rectifier.

I recently visited HVAC Manufacturing’s factory in Texas to review their product line, review ABBs implementation of the product, the SAV, HVAC Manufacturing’s other product offerings, etc.

This very conversation came up (almost in the exact way that you worded it). HVAC Manufacturing is definitely using their SAVs for labs where flow tracking is required. We talked in great length about the value the flow tracking and lab grade SAVs will bring to the SIs. We also discussed the fact that we can’t do the flow tracking across the BACnet network as a peer to peer point since it doesn’t meet most of the engineering specs out there. We discussed doing this over STAT bus as you suggested above.

Based on the conversations that I had with the HVAC Manufacturing and ABB it sounds like they want to start out by getting some traction on the SAVs and the factory installed controllers (consider this phase 1). Since flow tracking will require another custom application and some firmware upgrades/ enhancements it will be something considered for the future (hopefully phase 2).

I requested this feature on the spot because we work on several jobs where we have to leave things like this up to Phoenix or Accutrol.

I will state that HVAC Manufacturing works very closely on the entire lab/ life sciences line for Siemens. With their experience in this industry, I am hoping that they can work with some of ABB’s application engineers to get something comparable released for us to utilize. Just like everything they need to see the demand from the SIs so it can be considered for development.

Yes, it is possible. You will need to setup your JACE for BBMD on the BACnet IP port. You will need to set routing/ maintain routing to true. You will need to put the JACE IP address into your CXproHD software settings under BBMD (also select the correct Ethernet interface in your settings so it knows how to connect back to your computer). You will also need to put the JACE IP address into your site BBMD address. Make sure your site is setup for a BACnet IP connection not a serial connection. Everything should work from there.

Let me know if you have any questions.

If you’re making a BACnet IP connection to the CBV through a router using CXproHD it won’t allow you to change the controller baud rate. I have always had to do it over serial. I have never had any problems using NBpro over BACnet IP though. We have used NBpro over a full range of firmware and always had the same result.

When it comes to CXproHD, I suppose I could see some differences, but I would think your ability to adjust the baud rate on a controller using a BACnet IP connection wouldn’t be dependent on the firmware version of the controller. I haven’t experienced the issues that you have described, but we haven’t necessarily tried it in all of the different ways that you described. For the most part we always do it over serial since we’re using dealing with a single controller being put onto a legacy network. If for some reason we have a whole network of controllers and someone forgets to set the baud rate we have always done it over NBpro with no issues.

[Jeremy King]

There are a few different ways to accomplish this. I have listed some ways to do this:

Netlink: If you connect to the CBV controller over serial using Netlink and you have the latest Netlink screens unlocked and loaded you can click on “Controller Setup” at the top the screen to setup the CBV controller addressing and baud rate.

CXproHD: If you connect to the CBV controller over serial using CXproHD and click on the “Controller” tab at the top of the screen you will see “BACnet Configuration”. Click on “BACnet Configuration” and you will see a dropdown menu that shows MS/TP baud rate. It will allow you to change it to 19200 here. NOTE: If you’re using a BACnet IP connection this will be grayed out.

NBpro: If you make a BACnet IP connection to the MS/TP device through a BACnet router, Aspect, or Integra you can perform a discovery through NBpro. If you click on the device and expand the attributes of the “Device Object” you can change the baud rate by adjusting the value of (CP) communication baud (50000). If you change the baud rate over the network, you should power cycle the controller.

Let me know if you have any additional questions.

The Schneider EcoStruxture server is responsible for DHCP? Typically, there is a separate DHCP server that is managed by the customer’s IT department.

If the ABB controller is setup for DHCP and you have a valid DHCP server on site, then it should automatically assign any IP device that supports DHCP regardless of brand. Typically, it is good practice to make sure that the DHCP server keeps a reservation on a specific IP address assigned to a specific device to assure that you can always find it.

It can be difficult to prevent someone from using the HOA switches when it isn’t desired. There isn’t a whole bunch someone can do with this, but there are a few things that we do that helps with this. The first thing we do is always install the controllers in locked control panels. Only qualified personnel will have keys to the panels. The second thing we do is we either look at the “Override Slot” on the IO point or look at the “Overridden” BACnet property of the proxy point to send out an alarm when someone has put the HOA switch in manual. We usually create an alarm class just for HOA overrides. This allows the operator to simply go to their alarm console and filter by HOA overrides. This doesn’t really keep them from doing it, but at least you know about it.

We have had similar issues to what you have stated next to item #1. We had some random issues across 12 different buildings that we utilized these screens. The most common issues were either the screens locking up OR the screens losing connection with the target controller as you mentioned. The only way to correct the issues was to perform a reboot. When it came to the connection issues we found that the automatic system restart time on our screens was also set to occur at 3 a.m. In our case, this setting worked and didn’t cause us any issues. The setting that corrected the connection issues in our case is called “Auto Reload after Page Error”. The default setting is 0 (which disables this function). We were instructed to change this to 30 seconds. This allowed the screen to auto refresh until the connection was re-established. I have included the document that we were sent on this topic.

I haven’t really messed around with exception schedules on the eXplore screen, so I can’t really comment on your other issue. Have you reported the issue to ABB technical support?

Whatever you say man. Just trying to help you.

I assume you got that message when you clicked on where the image should be? In your 2nd picture above, the icon under “Custom Logo” means that your browser deems that the image isn’t secure. I just received an email today where every single image looked like that and if I clicked on them it would say things about being forbidden or invalid certificate, etc. I had to indicate that I trusted the embedded images. I would see the same problem across multiple browsers until I trusted the source.

If that isn’t your problem, then something isn’t setup correctly in your web service. Do you have a complete picture of your web service settings? What login template are you using?

I just logged into sites running 4.10, 4.11, and 4.12. All of our custom logos and embedded images are showing up.

[Jeremy King]

Based on your picture it looks like your logo isn’t coming through due to some sort of browser problem (like the image is being blocked). Are you able to go to other websites with similar small icons/ logos and see them? When I saw this problem the last time, I couldn’t see pictures on sites like Linkedin and such. The icon looked similar to what you’re showing in your picture. I ended up figuring out that it was a security setting in the web browser itself. I had to approve various exceptions for the website to get small logos/ images to show.

Have you tried multiple browsers and multiple computers not under your company domain? The reason I ask this is because when I had a similar issue, our company profile setup in our firewall/ antivirus would block images like that in the browser. I had to go through our IT department to assure that embedded logos/ images could be viewed in my browser.

We usually use History Import into a Supervisor rather than History Export from the JACE. A History Export Pushes from the JACE to the Supervisor and History Import Pulls from the JACE into the Supervisor. Your history files on the JACE will still intact with either method. The history import and export functions are solely making the connection between the history services on the JACE and Supervisor.

You can utilize a “Status Demux” block to extract the “overridden” status from the point in question. You will link the point you want to monitor to the “IN” slot of the “Status Demux” block. (There is a IN slot for all of the different point types). You will link the overridden slot to a “Boolean Writable” point that you drop from kitControl. You will add an alarm extension to that point in order to route your overridden alarm. When you start talking about a low priority alarm, I assume you want it to show on the alarm console, but not get emailed out. This gets setup by creating an additional alarm class and assigning these override alarms to it. Additional alarm classes can be added by pulling them out of your alarm palette. When you setup the alarm class, you can define the priority levels. The lower the number the higher the priority. You can then link this class to a separate override alarm console or do whatever you want with it.

Starting in version 4.12u1 there was a change to the file location requirements. The new specified file path now needs to be in the secure/ private station home. There was something about this change on Niagara Central. You will need to create a new directory called “public” within the folder of the station itself. You can add this folder through workbench or simply just go through your Windows file directory path. You will add your custom logo into the “public” folder. You will then go into the web service and manually create a new slot (baja:string) that points to the location of your custom logo. After you complete this step, you should see your custom logo above your login window again.
