I have a T3 TB-11i that is frequently freezing the screen and I sometimes find it re-booting. I’m thinking it needs replaced. What is the sequence for backing up the entire controller and then dumping in to a new one?
In addition, what is the proper format for adding a point to a graphic screen located on one controller where the point is on the mstp bus? I tried the panel number followed by point type and number, did not work. Then I used bacnet address followed by point type and number, still doesn’t work. The screen froze for several minutes while trying to add this point.
Should not have to swap hardware like that, let’s first backup the program file:
T3000 → File → Save as
Then update the firmware:
T3000 → Help → Check for updates → Update T3000
Then update the device firmware itself in the same dialog.
Check over the power supply:
With one transformer powering several devices you need to be extra certain 24vac is not crossed up between any of the devices. If you are using a DC power brick, make sure its not a low end one with high frequency harmonics feeding into your system. Tie ground to earth at each cabinet and each power supply.
Set up a trend log on a slowly ramping variable so you can see just how often its resetting:
IF INTERVAL( 0:0:10 ) THEN VAR1 = VAR 1 + 1
IF VAR1 > 100 THEN VAR1 = 0
The graph will show a sawtooth ramp for normal operation and sudden jags for resets.
After the update and grounding checkup, if you see more than one reset a week you can send the prog file to our team and we’ll check through it.
Currently, Bacnet MSTP points cannot be displayed in Graphic.
Please connect the Bacnet MSTP devices to the RS485 Main / Sub port of T3‑Nano, T3BB or T3LB.
This will enable them to be recognized as network devices.
At this stage, only network-based Bacnet IP is supported temporarily.
For Bacnet IP devices to link corresponding points, you can use commands such as 3VAR4, 3IN5, 7OUT8 for data mapping.
Here, the first number represents the panel number.
By this, I think you mean beacnet objects cannot be displayed in the graphics, like 7777AV2 would not be recognized.
But certainly you can place any of the implicit T3000 objects like 2VAR1 and 33IN2 on the displays. And OAT where that’s the user name for any T3000 object on any controller in the building.
