Safety
Definitions and Symbols
WARNING
This symbol indicates high voltage. It calls your attention
to items or operations that could be dangerous to you
and other persons operating this equipment. Read the
message and follow the instructions carefully.
This symbol is the “Safety Alert Symbol.” It occurs with
either of two signal words: CAUTION or WARNING, as
described below.
WARNING
Indicates a potentially hazardous situation which, if not
avoided, can result in serious injury or death.
CAUTION
Indicates a potentially hazardous situation which, if not
avoided, can result in minor to moderate injury, or serious
damage to the product. The situation described in the
CAUTION may, if not avoided, lead to serious results.
Important safety measures are described in CAUTION (as
well as WARNING).
Hazardous High Voltage
WARNING
Motor control equipment and electronic controllers are
connected to hazardous line voltages. When servicing
drives and electronic controllers, there may be exposed
components with housings or protrusions at or above
line potential. Extreme care should be taken to protect
against shock.
Stand on an insulating pad and make it a habit to use only
one hand when checking components. Always work with
another person in case an emergency occurs. Disconnect
power before checking controllers or performing
maintenance. Be sure equipment is properly grounded. Wear
safety glasses whenever working on electronic controllers or
rotating machinery.
Warnings and Cautions
This manual contains clearly marked cautions and warnings
which are intended for your personal safety and to avoid any
unintentional damage to the product or connected
appliances.
Please read the information included in cautions and
warnings carefully.

C441 PROFIBUS Module User Manual MN042002EN—July 2015 www.eaton.com 1
Overview
The C441 PROFIBUS communication adapter is a DPV0
slave device used to connect the C441 Motor Insight®and
C440 protective relay and S611 and S811+ soft starters to a
PROFIBUS network. The C441Q/S PROFIBUS adapter
connects to the side of the Motor Insight and the S611 soft
starter, and allows the user to access setup parameters and
IO data of the Motor Insight and the S611 over a PROFIBUS
network.
The C441QS/SS is a stand-alone PROFIBUS adapter that
connects to the C440, S611 and S811+ via hardwired
connections (DO/DI) and allows the user to access setup
parameters and IO data of the C440, S611 and S811+ over
a PROFIBUS network.
The C441QS/SS can also be used as a 4 digital input, 2 relay
output stand-alone IO module on a PROFIBUS network.
The C441 PROFIBUS communication adapters provide the
user with the ability to:
●Configure C441 Motor Insight, C440 OL relay, S611 and
S811+ soft starter and stand-alone IO setup parameters
over a PROFIBUS network
●Create custom IO assemblies based upon their
applications needs
●Exchange IO between a master and slave over a
PROFIBUS network
●Read out diagnostic information concerning the health
of the devices connected to the C441 PROFIBUS
interface modules

Mounting
The C441 PROFIBUS adapters are designed to be installed
on the right side of the Motor Insight base unit or the S611.
Figure 1. Installation Diagram
1. Align module with side of Motor Insight base unit or
the S611.
2. Slide module bottom pegs into appropriate slots.

module together.
4. Connect 24 Vdc power, PROFIBUS cable, and IO
connector if desired.
Note: For S611 Soft Starter applications, it is recommended
to mount a C441QS or C441SS module beside the
S611 and wire the D0/D1 terminals between the two
devices. More information on this is provided later in
this document.

Connecting the C441, C440, S611 and S811+
to a PROFIBUS Network
Connecting a C441Q/C441S to a C441 Motor
Insight or S611 Soft Starter
The C441Q and the C441S modules connect to the C441
Motor Insight and S611 Soft Starter by plugging these
PROFIBUS modules into the side of the C441 Motor Insight
and S611. As an option, the C441QS and C441SS may also
be wired to the S611 soft starter via the DO/DI terminals on
each product as shown below.
Connecting a C441QS/C441SS to a C440 Overload,
S611 Soft Starter or S811+ Soft Starter
The C441QS/SS modules communicate to the C440, S611
and S811+ by wiring the D0 terminal on the C441QS/SS to
the D0 terminal on the C440, S611 and S811+ and the D1
terminal on the C441QS/SS to the D1 terminal on the C440,
S611 and S811+. The C440 requires a C440-XCOM to be
added to the C440 per the following. The D0/D1 terminals for
the C440 are on the C440-XCOM module. All the other
devices listed above have D0/D1 terminals on a connector
directly attached to each product.
Figure 5. C440 to a C441QS/SS

S811+ to the C441QS/SS
The D0/D1 terminals are on a separate terminal strip from
where the 24 Vdc terminals are located on the S811+.
Connect D0 on the S811+ to D0 on the C441QS/SS and D1
on the S811+ to D1 on the C441QS/SS.
PROFIBUS Connection
The PROFIBUS port uses the standard DB9 PROFIBUS
connection. Refer to the figure below for details on the pin
out of this connector.
Figure 7. Pin Out for PROFIBUS DB9
24 Vdc Power
The C441 PROFIBUS adapter is powered from an external
24 Vdc supply wired into the 5-pin black header (J2) located
on the top of the adapter next to the 8 pos DIP switch.
Note: Connections to pins 2 and 4 for the C441Q/S modules
are only required if Modbus communications are to be
implemented.
Connections to pins 2 and 4 for the C441QS/SS are
the required communication connections to interface
the C440, S611 and S811+ devices to a PROFIBUS
network.

Setting the PROFIBUS Address
PROFIBUS Address
The PROFIBUS address is set using the DIP switches
located on the top of the C441 communication adapter. The
address can only be set with the hardware DIP switches. The
address is in binary with the major units numbered to the
right of the switch on the label. Adding up the major units set
to ON will provide the address of the adapter on the
PROFIBUS network.
Notice
The address specified in the switches is only used by the
adapter at the time the adapter is powered on. Changing
these switches during operation will have no affect until the
next power cycle or reset.
Notice
A PROFIBUS address setting of 0 will result in the C441
using the default Station Address of 125. Any PROFIBUS
Station Address setting greater than 125 will result in the
C441 using the default Station Address of 125.
Table 15. PROFIBUS DIP Switch Settings
Example: To set a MAC ID of 25, DIP switches 5, 4, and 1
need to be turned ON, with all others OFF.

Power and I/O Wiring Diagrams for the C441Q
and C441S Modules
The C441Q module contains four 24 Vdc inputs and two
relay outputs. The two relay outputs provided are one
form A (NO) and one form C (NO, NC).
24 Vdc Inputs
The 24 Vdc input circuit is capable of both isolated and
unisolated behavior. The isolated inputs share a single
common tie point. A 24 Vdc current limited source/ground is
provided in the situations that require locally supplied input
signal voltage. To use the unisolated inputs, tie the 24 Vdc
ground/common to the isolated common.
Figure 9. C441Q: 24 Vdc Wiring Diagram
Note: Do not connect a 24 Vdc source to pins 6 and 7. The
“I/O Power: 24 Vdc” is to be used only in conjunction
with the inputs. It is a 24 Vdc output intended to only
supply signal power for the inputs. When using the
24 Vdc input supply, pin 6 should only be connected to
pin 5 (24 Vdc input supply common to input common).
See example wiring diagram above. Any device using
the provided 24 Vdc input supply must have 500 V
isolation from ground. Example devices include
pushbuttons and auxiliary contacts.
