Hi,

I am doing a PLC project and I need to check the status of my IOs by polling my parallel Port very often. I thought of using the Timer control component of Visual Basic but unfortunately is not that fast. It says that you can select interval of 1ms but basically is an interval of 52ms!

Is there any component I can use so that I can poll my parallel port almost every 1ms? I have seen that there is an ActiveX component from Mabry.com called HitTime but unfortunately it is not fo free.

Please advice and many thanks for your help.
