Hi, i just bought an air Flow Sensor but by defult is in Modbus so i went to the T3000 and try to set the device to bacnet.
I use config Tab but the baud rate and protocol is predefine as modbus,11500 and can not change the
Value.
Anybody knows what am i doing wrong?
Thanks
Regards
I would get started by updating the firmware and the T3000 front end while you’re at it. Do that under T3000 → help → check for udpates.
Standing by to help more.
Hi maurice
Thanks for your Replay.
I already did that.
the last versión is january 21 2025
Our crew will check into this and report back tomorrow.
Current version of the firmware does not support being scanned by T3000 after switching to BACnet protocol.We will made it support this later.
If you want to use other BACnet software to connect to air flow, you can use the modbus tool to directly change the modbus registers to switch to the bacnet protocol.
Hi, Lijun.
Thanks for the feedback.
I understand this.
With T3000 can not change the protocol from modbus to bacnet. Got it.
I already have a software but it is totally bacnet.
So if i connect the sensor to the network the air Flow Sensor Will adjust itself to bacnet protocol and baudrate?
Second if i got it wrong.
Use a modbus other than the t3000 scan and change the protocol from modbus to bacnet and change the baudrate as well.
Thanks

Lijun.
I got it .
Thanks for the info
The devices support BACnet, for now you will need to write a Modbus register in order to switch protocol to Bacnet. Write to modbus register 10 and set it to ‘1’ in order to select BACnet protocol.
It should be noted that once you switch to BACnet, you can no longer communicate with it using the T3000 software (yet). You have to connect it using standard BACnet software. If you would like to switch back to the Modbus protocol you can do that by changing the BACnet object for the protocol setting.
We can add bacnet support from T3000 in a week or so.
