BACnet quick-start sequence
The following steps summarize the process for enabling and configuring BACnet on
the ACS320:
1. Enable BACnet protocol: Set drive parameter
9802 COMM PROT SEL =
BACNET (5).
Note: If you cannot see the desired selection on the panel, your drive does not
have that protocol software in the application memory.
•
To confirm this selection, read drive parameter 5301 EFB PROTOCOL ID . It
should read x5xx (where “x” is any value).
2. Place the BACnet channel in “reset”: Set drive parameter 5302 EFB STATION ID
= 0.
•
This setting holds the BACnet communication channel in reset while
remaining settings are completed.
3. Define the MS/TP baud rate.
• Set drive parameter 5303 EFB BAUD RATE = appropriate value.
4. Define the Device Object Instance ID.
• To define a specific device object instance value, use drive parameters 5311
and 5317 (object instance values must be unique and in the range 1 to
4,194,303).
• To use the drive’s MS/TP MAC ID as the device object instance value, set
drive parameter 5311 and 5317 = 0.
5. Define a unique MS/TP MAC ID. Set drive parameter 5302 EFB STATION ID =
appropriate value.
•
Once this parameter is set to a non-zero value, current BACnet settings are
“latched” and used for communication until the channel is reset.
• In order to participate in MS/TP token passing, the MAC ID used must be
within the limits defined by other masters’ “Max Master” property.
6. Confirm proper BACnet communication.
• When BACnet communication is operating properly, drive parameter 5316
EFB PAR 16 (the MS/TP token counter), should be continually increasing.
• Drive parameter 5306 EFB UART ERRORS , should be stable.
