Appendix C—Optional Communication CardsPower Xpert C445 Global Motor Management Relay MN042003EN—October 2016 www.eaton.com 225PROFIBUS Communication CardIntroductionThe PROFIBUS communication card is an optional add on tothe C445 Base Control Module that allows the user tocommunicate via PROFIBUS. This module allows aPROFIBUS master to fully control and monitor the C445. Thismodule functionally supports both PROFIBUS DPV0 andDPV1 functionality.The main purpose of PROFIBUS DPV0 is fast Cyclic Dataexchange between the DP master and periphery devicessuch as the C445 Motor Management Relay.PROFIBUS DPV1 is an extension of the DP protocol. Themain purpose for PROFIBUS DPV1 is to add Acyclic Dataexchange of parameters.Installing the PROFIBUS Communication CardThe PROFIBUS Communication Card is installed directly intothe Base Control Module. To install the module, follow thestep by step directions:1. Remove the blank cover when the unit is not powered2. Locate the communication card slot3. Plug the PROFIBUS communication card into locationFigure 176. Installing the PROFIBUS Communication CardPROFIBUS Communication Card & DIP SwitchesThe DIP Switches on the Base Control Module are used fortwo purposes when an optional PROFIBUS card is installed –to set the node address and baud rate for an optionalModbus port if included and for the PROFIBUS nodeaddress. Per the diagram, if the optional RS-485 Modbusserial port is present, DIP Switches 1 – 7 are used todetermine the node address on both the PROFIBUS andModbus serial protocols. When the Modbus serial port ispresent, it also uses switches 8 – 9 to set the baud rate forthat port. If the optional Modbus serial port is not present,the DIP Switches are used for the PROFIBUS node addressonly. The C445 PROFIBUS card auto-detects the data rateset by the PROFIBUS master.Supported PROFIBUS Data Rates● 9600● 19200● 45450● 93750● 187500● 500000● 1.5M● 3M● 6M● 12M
