Communication interfaces
This chapter describes how the inverter can be controlled by external devices over a
communication or fieldbus network through an optional fieldbus adapter module.
System overview
Important: This inverter is not allowed to be connected to a public network. See Terms
and abbreviations on page 9 and Cybersecurity for ABB drives Technical guide
[3AXD10000492137 (English)].
The inverter can be connected to an external control system through an optional fieldbus
adapter that is mounted on the inverter control unit.
The inverter interface for a fieldbus connection is fieldbus adapter B (FBA B), while the
fieldbus adapter A is reserved for internal inverter communication. The inverter can be
configured to receive all of its control information through the fieldbus interface(s), or the
control can be distributed between the fieldbus interface(s) and other available sources.
Note: The text and examples in this chapter describe the configuration of one
fieldbus adapter (FBA B) by parameters 150.31...150.33 and parameter groups
154 FBA B settings…156 FBA B data out.
