Example of a simple set-up of BACnet
This example shows the necessary steps to set up the TR200 BACnet interface with the following system re-
quirements:
• MS/TP running at 38,400 baud
• MAC address 20 for the TR200
• BACnet Device Instance 0 1025
• Highest number of a master stack is 35
• Start/stop of drive from BACnet only
• Reference from BACnet
• Read status of drive (actual speed)
Set the following parameters:
Name Par. number Value
Protocol 8-30 Drive option [9]
Address 8-31 20
Drive Port Baud Rate 8-32 38,400 Baud [4]
Coasting Select 8-50 Bus [1]
BACnet device instance 8-70 1025
MS/TP Max Masters 8-72 35
After the parameters have been set according to the table above, the drive has to be unpowered and repowered
before the changes take effect. When the adjustable frequency drive is detected by the BMS, the drive can be
controlled by BV:1, which will start the motor if set to [1]. Setting AV:0 will set the speed reference of the drive.
The actual speed can be monitored via AV:1. See also
