We’re troubleshooting an intermittent issue and I suspect it has to do with the use of a Momentary Button where the On Time property is less than the polling rate of the project. We’re going to try changing the buttons to One-Shot buttons, but it’s got me curious about how Ignition does its timing.
Do tag read/writes get queued up and sent at the frequency of the polling rate or are they asynchronous?
For example, say I have a project with a polling rate of 10 s and a Momentary Button with an on time of 1 s, would this be a possible sequence of events?
0:00, project polls and updates all the tags
0:05, Momentary Button is pushed and the value is 1
0:06, Momentary Button timer expires and the value is set back to 0
0:10, project polls and updates all the tags, writing a value of 0 to the button’s bound tag
Basically, would the button press get “lost”?
