I have a button on my form that is used to start a machine. The standard procedure is currently to press and hold the button for 5 seconds, during which time a startup warning horn goes off. Releasing the button will abort the start up procedure.
My problem is that after exactly 3 seconds I loose the input from the button on the form. I don't get any error message or anything, it just stops writing the data to the tag.
I should point out that I am a long time PLC programmer (over 30 years) and a very short time Visual Basic programmer (I'm only on chapter 3 of Beginning Visual Basic 2012).
Does anyone have any Ideas on what might be going on?
