Dear Experts,

I am a pure mechanical guy with very little PLC knowledge. I have a challenge to operate a PLC via VB.net program. I searched the internet and found two libraries (Free ;-)  ) for doing that. But the problem is I dont have much understanding libreries. If any one can provide simple program like reading 0-10VDC input value from the PLC and display it on PC screen by using VB program. 

Appriciate your advises and helps.

One more questions: to direct connect PC and LOGO8 can we use straight eathernet cable? we need to use crossover cable?

Thanks in advance
