Trouble in connecting ATV58 modbus via RS232/RS485 link.

I am new to modbus, I need to connect ATV58 Speed drive to PC to monitor the Speed through VB. It connected RS232/RS485 link with serial port and it work fine with "power suite". But I am unable to connect same with my simple VB Program to monitor the motor Speed.

Any one help me in this regard?

Thanks
