I have a Boolean OPC tag which I had inverted (Ignition to display True when False in PLC, and vice versa) in 7.9, which worked well. In 8.0.5 it doesn’t seem to work the same.

Changing the “Scale Mode” property between “Off” and “BitInversion” doesn’t have an effect on the tag value in 8.0.5.

Should be fixed in 8.0.7+
