PROFIBUS Cable Connection Options
The PROFIBUS card provides two options for PROFIBUS
cable connections
1.
PROFIBUS 9-pin D-SUB connector
2.
3-position screw connector with the following pin
assignment:
●
Pin 1 – RxD/TxD negative (green)
●
Pin 2 – RxD/TxD positive (red)
●
Pin 3 – Protective Earth
Note:
The DIP Switches located beside the 3-position
connector are only used when the 3-position
connector is used for connecting the card to the
PROFIBUS network. These switches must be turned
Off if the D-shell connector is used to connect this
card to PROFIBUS. These switches are used to turn
network termination On/Off. If the 3-position
connector is used to connect the C445 PROFIBUS
card to the PROFIBUS network and if this card is an
end device on the network, turn both switches On to
enable termination. Otherwise, turn both switches Off
to disable termination.
PROFIBUS D-shell connector information is shown below.

Configuring using the
in
Control software tool
There is a Modbus serial DTM/Driver for the
in
Control
software tool. This DTM is used to communicate from a
computer running the
in
Control software tool using either a
USB to micro USB cable or a USB to RS-485 serial cable.
These interfaces may be used to connect to the C445 Motor
Management Relay. Refer to the
in
Control software tool user
manual for additional information (publication MN040013EN).
Configuring using The C445 PROFIBUS GSD file
The GSD file for the C445 Motor Management Relay may be
found at the Eaton website:
http://www.eaton.com/C445
This file is compatible with any PROFIBUS software used to
configure a PROFIBUS network. It provides input/output
information for cyclic polling, configuration file parameters
and diagnostic data. It also contains parameter information
that may be used for acyclic messaging.
