Disable Subscriptions
Works the first time the screen is displayed, if you switch to another screen and then back to that screen it starts polling automatically . I see in the code that it does what its programmed to do , but really don't know how to fix it.
All my HMI;s I now add a Connect Button and a Disconnect Button the to each screen , In some cases it seems to give the screen time to load and display with fewer problems. Also Ive found that if a plc goes offline for some reason , the screen may become unresponsive and I'll have to restart the HMI. I can click disconnect and after a few seconds connect , sometimes I can prevent it from locking up and having to restart the HMI.
I have noticed this problem especially with more than one Allen Bradley Micrologix Controllers on a screen , add a compact or control Logix to the mix and you loose one off them doesn't seem to really affect it
