Hey guys, I was wondering if anyone encountered this unexpected behavior before. **Background:** I currently have a SQL query tag that is a string (a 6 digit product number). Execution mode: Fixed Rate Execution Rate: 60,000 Rest of the tag properties: Default Project com mode: read-only I have binded this to the text value of a generic label in Vision. **Problem:** When I toggle preview mode it throws an error: Error writing to tag `TAG PATH REMOVED` Bad\_GatewayCommOff This is good that it is not writing because I did not want it too! I have done nothing to out of the ordinary to make it write to the tag. I’m a little concerned why it is doing that. The value of the tag does not change nor does the value of the label. This happens with different tags too. Please help I do not want to be accidentally writing to these tags. ---

Is the binding set to bi-directional? If so, uncheck it Note: dragging on a tag into a Window to a property value will default bind it as bi-directional (this may have changed in v8 can’t remember) ---

Oh wow yes it is. I had no clue about that. Looks like thats is enabled for all the other tags that I binded to component properties in the project. (500+ ☹ ) Strange that I am only experiencing the write back on Labels with string tags and on no other components. Is there a way that I could change the default? I would NEVER want any binding to be bi-directional. ---

No way to default it, but you can find/replace the XML of the Window(s) to unset bi-directional. Search for: `` and set 1 to 0 > [@davidwc](#): > > I would NEVER want any binding to be bi-directional. So you don't have any operator inputs? ---

Nice, I will have to try that XML tip, thanks! No we dont have any operator inputs we are strictly data acquisition and analysis from machines. Thanks for your help!!!
