All of my Modbus tags are showing “Bad\_NotConnected” in the Tag Browser, however I can successfully write values to the PLC and see them change in there. I have added them as addresses under the device and I can change and read them from the OPC Quick Client Successfully. When I then put that tag into the tag browser I get the same “Bad\_NotConnected” flag next to the tag. Due to this I can’t use read values
