326 Fieldbus control with fieldbus adapter
The drive can be set to receive all of its control information through the fieldbus
interface, or the control can be distributed between the fieldbus interface and other
available sources, eg digital and analog inputs.
The drive can communicate to a control system through a fieldbus adapter using eg
the following serial communication protocols. Other protocols may be available;
contact your local ABB representative.
• PROFIBUS-DP (FPBA-01 adapter)
• CANopen (FCAN-01 adapter)
• DeviceNet™ (FDNA-01 adapter)
• Ethernet (FENA-01 adapter)
• Modbus RTU (FMBA-01 adapter. See chapter Fieldbus control with embedded
fieldbus on page 301.)
The drive detects automatically which fieldbus adapter is connected to drive terminal
X3 (with the exception of FMBA-01). The DCU profile is always used in
communication between the drive and the fieldbus adapter (see section Fieldbus
control interface on page 330). The communication profile on the fieldbus network
depends on the type and settings of the connected adapter.
The default profile settings are protocol dependent (eg vendor-specific profile (ABB
drives) for PROFIBUS and industry-standard drive profile (AC/DC Drive) for
DeviceNet).
