    Hi,
    I'm not sure exactly what your trying to do, but I wrote some code to turn paraelle port pins on / off. You can get a +5V on / 0 off. I have used this to build small robots and control appliances through the paraelle port with a vb program. If I can help out in any way email me at

    Hi! CyberCarsten, I think you need to check out this fews think first.

    First I think you need to check what type of communication port is available at your PLC before you start your VB programming.

    Second, check out is there any protocol needed in sending command to the PLC?
