Hi, I am using a checkbox to control a boolean tag in a CompactLogix PLC.

The checkbox works most of the time, but sometimes it displays the incorrect state and does not update itself.

An interesting thing to note is that this only occurs if I change the tag value with the checkbox in the client.

Whereas, if I change the tag via the tag browser the checkbox always shows the correct state.

The issue does not happen with a toggle switch.

Any ideas how to resolve this?

Is your binding set to bi-directional?

Yep, like I mentioned above the identical binding on a toggle switch works correctly.
