Device interfaces
5.2.1
Local device interface
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" operating, monitoring and parameterizing software (see chapter Accessories
(Page 277)) using a PC and a connecting cable.
5.2.2
PROFIBUS/PROFINET interface (optional)
The SIRIUS 3RW44 soft starter can be equipped with an optional PROFIBUS module (only
available for products delivered after 04/2006) or with an optional PROFINET module (only
available for products delivered after 06/2013). The soft starter can be connected to
PROFIBUS/PROFINET, operated and parameterized via the interface. The "Soft Starter ES"
operating, monitoring and parameterizing software (see chapter Accessories (Page 277))
can also be connected to this interface using a PC and a connecting cable.
Simultaneous operation of a 3RW44 with a PROFIBUS/PROFINET interface is not possible
in networks where one line conductor is grounded.
5.3
External display and control module (optional)
When de-energized, the external display and control module can be connected to the local
device interface via a special connecting cable.
After switching on, the SIRIUS 3RW44 soft starter automatically recognizes that the external
display and control module has been connected. The 3RW44 display will be inverted and the
display and control module's display will be shown normally.
The control keys of the 3RW44 will be inactive, meaning that normal handling is only
possible via the external display and control module.
