PROFIBUS Communication Card

Introduction
The PROFIBUS communication card is an optional add on to
the C445 Base Control Module that allows the user to
communicate via PROFIBUS. This module allows a
PROFIBUS master to fully control and monitor the C445. This
module functionally supports both PROFIBUS DPV0 and
DPV1 functionality.
The main purpose of PROFIBUS DPV0 is fast Cyclic Data
exchange between the DP master and periphery devices
such as the C445 Motor Management Relay.
PROFIBUS DPV1 is an extension of the DP protocol. The
main purpose for PROFIBUS DPV1 is to add Acyclic Data
exchange of parameters.
Installing the PROFIBUS Communication Card
The PROFIBUS Communication Card is installed directly into
the Base Control Module. To install the module, follow the
step by step directions:
1. Remove the blank cover when the unit is not powered
2. Locate the communication card slot
3. Plug the PROFIBUS communication card into location

PROFIBUS Communication Card & DIP Switches
The DIP Switches on the Base Control Module are used for
two purposes when an optional PROFIBUS card is installed –
to set the node address and baud rate for an optional
Modbus port if included and for the PROFIBUS node
address. Per the diagram, if the optional RS-485 Modbus
serial port is present, DIP Switches 1 – 7 are used to
determine the node address on both the PROFIBUS and
Modbus serial protocols. When the Modbus serial port is
present, it also uses switches 8 – 9 to set the baud rate for
that port. If the optional Modbus serial port is not present,
the DIP Switches are used for the PROFIBUS node address
only. The C445 PROFIBUS card auto-detects the data rate
set by the PROFIBUS master.
