How to Configure the System

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

Bus [1]

 

 

BACnet device instance

8-70

1025

 

 

MS/TP Max Masters

8-72

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 Analog Input and Output Objects section.
