Hi I am having issues with all types of button (one shot, momentary, toggle…). I made a simple toggle button and bind an opc tag to it. When pressed, I did not see any changes to the PLC, but if I used a script, then it worked. Can someone help please? Yes, I did tried with different button types, results were the same. They only worked when scripted. ---

Are you project comm settings set to read/write? ---

Yes, comm is set to read and write ---

Could you have something else writing to the same tag, either in your PLC or ignition project? Also, which event handler are you using? ---

No, only the OPC tag from Ignition can write to this PLC tag. What do you mean by event handler? ---

This is one of my buttons that fires on a mouse release. ![image](https://us1.discourse-cdn.com/inductiveautomation/original/3X/1/c/1ce66b19fa5deca5ce4d01601b4a88ad182226fa.png) ---

I only use the event handler in the script, which worked. I like to use the button without writing the scripts. Where can i find this event handler without the script? ---

Pick an event, then use the Set Tag Value option. ---

No, you can use bindings. Most likely you are missing “bidirectional” in your binding. ---
