MODBUS TCP COMMUNICATION WITH SEW MDX61B DRIVE

[HARSHAL 0]

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
