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

Please also clarify which is better in terms of

2 - ease of use by users
3 - Ease of Installation
And a thank you
