A local device interface on the front side of the starter is provided as standard.
This interface can be used to connect either an optional external operating and
display module, or the "Soft Starter ES smart" operating, monitoring and
parameterizing software (refer to Chapter 9.3.8 "Accessories" , Software) using
a PC and connecting cables.
The SIRIUS 3RW44 soft starter can be equipped with an optional Profibus
module (only available for products delivered after 04/06). The soft starter can
be connected, operated and parameterized via the Profibus interface. The "Soft
Starter ES professional" operating, monitoring and parameterizing software
(refer to Chapter 9.3.8 "Accessories" , Software) can also be connected to this
interface using a PC and connecting cables.
Simultaneous operation of a 3RW44 with a profibus interface is not possible in
networks where one phase conductor is grounded.
