Data Channels
The InterBus-S system provides two channels for data transfer, the
process data channel (for fast cyclic transfer of time-critical I/O data)
and the
PCP channel (for acyclic transfer of non-time-critical, complex
blocks of data, e.g. parameter data).
The NIBA-01
InterBus-S Adapter
Module
The NIBA-01 InterBus-S Adapter Module is an optional device that
enables connection of an ABB drive to an InterBus-S system. The
module is considered a remote bus device by the host.
Through the NIBA-01 InterBus-S Adapter Module it is possible to:
•
Give control commands to the drive
(Start, Stop, Run enable, etc.)
•
Feed a motor speed or torque reference to the drive
•
Give a process actual value or a process reference to the
PID controller of the drive
•
Read status information and actual values from the drive
•
Change drive parameter values
•
Reset a drive fault.
The InterBus-S commands and services supported by the NIBA-01 are
discussed in Chapter 6. Please refer to the user documentation of the
drive as to which commands are supported by the drive.
The adapter module is mounted onto a standard mounting rail inside or
outside the drive unit, depending on drive type and configuration. See
the user’s manual of the drive for module placement options.
