Embedded fieldbus
• 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,
UART ERRORS
, should be stable. (With autobaud detection,
this parameter may increase until the proper baud rate is detected.)
7. Configure the Device Object Name.
• BACnet requires a unique name for each device on the BACnet network. Write
the Object Name of the Device Object of the drive to a unique text string using the
operator workstation or software tool capable of writing BACnet properties. The
Object Name cannot be modified with the ABB display panel and only the Device
Object name is writable in this product. We do not support writing of Device
Description.
