This is probably going to be a dumb question. (and given my fat fingers in typing STRP .. I'm already off to a good start)
Imagine if you will that I have two Pro-Face HMI panels and that each has a momentary button on a screen. Each Pro-Face talks independently to an Rx3i PLC via SRTP. But each button wants to write to the same %M address inside the PLC when it is pressed.
What will happen?
My assumption is some form of the latter situation combined with a dose of asynchronous random timing that may make the desired action sort of work sometimes. But is my assumption correct?

What will happen?
- Will I reliably get the %M in the PLC to turn on and off when the button on either Pro-Face is pressed?
- Or will the (lack of) pressing the button on one Pro-Face interfere with the opposite action on the other Pro-Face?
