Dear, apologies for the basic question, I'm still learning I have a dropdown list with following dataset Value Label 0 Select Route 112 Route\_1 122 Route\_2 111 Route\_3 e.t.c And also I have a OPC DA server with opc\_to\_plc boolean tag, for example: tag\_route\_1, tag\_route\_2, tag\_route\_3 How to bind Value and tag OPC DA, for example if select Route\_1 then tag\_route\_1 = 1, else 0 ---

Hi! You can create an event on the dropdown (onActionPerformed). When the value changes, you can read the value, and if the value is 1, update tag\_route\_1, if 2 then 2, and so on.... ![image](https://us1.discourse-cdn.com/inductiveautomation/original/3X/1/5/152515d708dfc04fc67da5bca8b057f254dacc63.png)
