Posted 26 Sep 2008 A module of ModBus doesn't exist for these PLCs. A solution is to put a C200H-ASCxx and to make you the protocol in language Basic that is it they make these modules. It can be very hard. Regards. Share this post Link to post Share on other sites
Posted 1 Oct 2008 Falpaw, Automation is partly correct... Yes, for modbus to work you need ans ASC02 card (generally) Secondly, omron issued the modbus slave and modbus master protocol programs for the ASC02 card years ago. If you choose to go down this path I can certainly upload the programs for you. Share this post Link to post Share on other sites
Posted 2 Oct 2008 Do you need Modbus Master or Modbus Slave code for C200HS? It makes a difference. Modbus Slave Ladder Code for C200HS and Others @ MrPLC.com Share this post Link to post Share on other sites
