Fieldbus control through a fieldbus adapter 631

Fieldbus control through a
fieldbus adapter
What this chapter contains
This chapter describes how the drive can be controlled by external devices over a
communication network (fieldbus) through an optional fieldbus adapter module.
The fieldbus control interface of the drive is described first, followed by a
configuration example.
System overview
The drive can be connected to an external control system through an optional
fieldbus adapter mounted onto the control unit of the drive. The drive actually has two
independent interfaces for fieldbus connection, called “fieldbus adapter A” (FBA A)
and “fieldbus adapter B” (FBA B). The drive 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 such as digital and
analog inputs, depending on how control locations EXT1 and EXT2 are configured.
Note: The text and examples in this chapter describe the configuration of one
fieldbus adapter (FBA A) by parameters 50.01 … 50.21 and parameter groups 51…53.
The second adapter (FBA B), if present, is configured in a similar fashion by
parameters
50.31 … 50.51 and parameter groups 54…56. It is recommended that the
FBA B interface is only used for monitoring.
