I 've observed that a change in a Numeric Text Field and/or a 2-State Toggle Switch (binding with OPC Tags) takes up to 10 second to be reflected on the component. The change consist in show the value of a OPC tag after a system.tag.write() call executed by a Momentary Button and/or focusLost and/or propertyChange events.
I’ve checked this behavior on the Controller side and you can observe an almost instantaneous change. This is not a critical problem rather a user experience one, as the application will be implemented with a user base with low to none technical knowledge.
I’m inclined to be a tag-reading issue. I can not find how to make this “delay” to be as short as possible. Any ideas on how to fix this??
Thanks for your time!
I’m attaching some sample code:
zone = event.source.selectedValue
