If I hide a screen does it stop communicationg with the plc
« on: October 29, 2014, 02:38:03 PM »
I built a HMI with more than one screen , when I open the 2nd screen I have it hide the 1st one. The hidden screen does it stop communicating with the PLC , If it does, is there a way to hide it and make it stop communicating or do  I just have to close it.

Also how many instructions can pole the PLC before some do not work ,

In the default MainForm, there is a snippet of code that shows how to stop the updating when a form is hidden.

There should be no limit on the number of reads.
