I-7540D-MTCP Ethernet/ Modbus to CAN Converter Quick Start User Guide Version 1.0 ------ 1 

Quick Start User Guide 

 

1. Introduction 

 

This  manual  introduces  the  user  to  the  methods  used  to  implement  the 

I-7540D-MTCP  module  into  their  applications  in  a  quick  and  easy  way.  This 

will  only  provide  with  the  basic  instructions.  For  more  detailed  information, 

please  refer  to  the  I-7540D-MTCP  user  manual  located  on  the  ICPDAS 

CD-ROM or download it from the ICPDAS web site:   

Fieldbus_CD:\CAN\Converter\I-7540D-MTCP\ 

or

The goal of this manual is focused on helping users to quickly familiarize 

themselves  with  the  I-7540D-MTCP  module  and  the  CAN-Modbus  TCP 

/Modbus  RTU  communication  converter.  Here,  we  use  two  I-7540D-MTCP 

modules  (called  the  I-7540D-MTCP_A  and  the  I-7540D-MTCP_B)  as  the 

example  will  demonstrate  how  to  use  the  I-7540D-MTCP  modules.  The 

architecture of this example is depicted below. 

 

When the I-7540D-MTCP receives a valid Modbus TCP command, it can 

convert  this  command  into  a  CAN  message  and  transmits  it  into  the  CAN 

network.  Another  I-7540D-MTCP  will  receive  the  CAN message  then  store  it 

into  the  buffer.  Meanwhile,  user  can  use  Modbus  RTU  command  to  get  the 

message back.
