Robot Modbus to ESP 32 wrover module

Hi,

I am trying to communicate ESP32 wrover module with UR5 modbus client using wireless ethernet to be clear connected Robot modbus ethernet port to router and Esp32 wifi module to same network. i tried pinging modbus with ESP32 actually it works but if i am trying to send a register output or digital output to esp32 from robot. It throws E2 error the adress which i used to send is listed in manual but couldn’t figure it out to resolve error. i have completely check the connection every thing is fine.

May i know robot modbus client supports to ESP32 if it does could you share any details it will be useful or any information have any body tried it before with similar communication.
