hi! I need help from you zafarsalam

How to setup dro info on lcd connected to arduino modbus slave on arduino with shillings code modbus slave???

Ihave included wire.h and liquidcristali2c.h for lcd in arduino code.
From now I ned help for how to send data from mach3 -->>>brain-->>serial modbus plugin--->>>arduino modbus slave ?????
many users have this done but no documentation on arduino code, no info about serial plugin configs,

Help  and thanks
