opc server vs serial port rs232

Post by mohmmadmustafa » Wed May 21, 2014 3:14 pm

Hello all
My participation in this first Forum
I am currently on the establishment of a program to simulate seminc plc by Visual Basic
But the problem lies in the choice of how to connect the computer with plc
Options
1 - Use opc server
2 - Using the serial port
Please also clarify which is better in terms of
1 - Speed
2 - ease of use by users
3 - Ease of Installation
And a thank you
