Modebus Slave Help!

[seokgi]

Hi!
I am making a MODBUS Slave program using RS-485.
I edit the incoming data to the RS-232 and put it in the Modbus Slave address, and then take the data through RS-485 from another SCADA program.
I tried several examples and it does not work.
I need help.
I upload a program I made. I do not know what went wrong.

I always appreciate your help.
