Overview
16
Time channel is used for standard cyclic data transfer and alarms.
There is no theoretical limit for the amount of connected nodes in
PROFINET IO network, but in practise, the programmable
controllers and number of available network addresses limits the
size.
The PROFINET IO protocol is specified in the IEC standards
61158 and 61784. The communication with a drive is specified in
the PROFIdrive profile (v4) published by PROFIBUS
INTERNATIONAL.

The RETA-02 Ethernet Adapter module
The RETA-02 Ethernet Adapter module is an optional device for
ABB drives, which enables the connection of the drive to a
Ethernet network. The drive is considered as a slave on the
Ethernet network. Through the RETA-02 Ethernet 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 Modbus/TCP and PROFINET commands and services
supported by the RETA-02 Ethernet Adapter module are
discussed in chapter Communication. Please refer to the user
documentation of the drive as to which commands are supported
by the drive.
The adapter module is mounted into an option slot on the motor
control board of the drive. See the Hardware Manual of the drive
for module placement options.
