  1. Hello everyone 

     

    I am working on modbus TCP protocols to communicate between SEW drive and Omron PLC CP1L-EM. I am following modbus TCP function block from Omron, But i have updated that block because of is not fit to SEW modbus communication. Currently, I am sending a control work to SEW but I am getting error on Modbus TCP from SEW drive, which is invalid data. So I am looking your help is you work with SEW drive before and communicate over modbus, then please let me know how to make a data string for read and write (SEW Drive function 23). I am using 3PD data structure. 

     

    Thank you


  2. hello Every one, 

     

    I am using a CP1-L PLC and want to communicate to domino ax350i printer over TCP/IP socket programming. For socket programming, I used Omron Function Block CPU012_SendCommand.  I defined network ID and node address. However, I am getting 0502 error which means routing table is not set yes. So, how can I set routing table for both devices?. my PLC on 192.168.250.1 and Printer is on 192.168.250.123 node 7000. 

     

    Can any one suggest me best way to do. 
    Thank you

     

    attached file is for what I did in setting and program for the communication.
